.NET Framework Versions by Soumyasch

Here is a collection of 8 video tutorials on some of the new components in .NET Framework versions 3.0 and 3.5. The presenter is Microsoft's Mike Benkovich. The videos focus on LINQ and WCF.

Version 3.5 of the .NET Framework was released on November 19, 2007. Version 3.5 uses version 2.0 of the CLR, and it installs numerous service packs on top of the CLR.

New Features of NET 3.5 Framework

• New language features in C# 3.0 and VB.NET 9.0 compiler
• Adds support for expression trees and lambda methods
• Extension methods
• Expression trees to represent high-level source code at runtime.
• Anonymous types with static type inference
• Language Integrated Query (LINQ) along with its various providers
• LINQ to Objects
• LINQ to XML
• LINQ to SQL
• Paging support for ADO.NET
• ADO.NET synchronization API to synchronize local caches and server side datastores
• Asynchronous network I/O API
• Peer-to-peer networking stack, including a managed PNRP resolver
• Managed wrappers for Windows Management Instrumentation and Active Directory APIs
• Enhanced WCF and WF runtimes, which let WCF work with POX and JSON data, and also expose WF workflows as WCF services.[26] WCF services can be made stateful using the WF persistence model.
• Support for HTTP pipelining and syndication feeds.
• ASP.NET AJAX is included
• New System.CodeDom namespace. (This was thought to be new and is in fact in the Visual Studio 2003 / NET 1.1 help)

Here is a collection of free video tutorials on SharePoint for Developers. The 16-part video series is presented by Microsoft's Mike Benkovich and Lynn Langit.

Microsoft SharePoint is also called Microsoft SharePoint Products and Technologies. SharePoint is a collection of products and software elements that includes:

• web browser based collaboration functions
• process management modules
• search modules and a document-management platform

SharePoint can be used to host web sites that access:

• shared workspaces
• information stores
• documents
• host defined applications such as wikis and blogs

All users can manipulate or interact with:

• web parts
• lists
• document libraries

Background:

The term "SharePoint" can collectively refer to a number of products ranging from the base platform to various services. The platform is Windows SharePoint Services (WSS), which is included with Windows Server and available as a free download for those with Windows Server licenses. (Vista users can use a helper application from Bamboo Nation to allow them to run SharePoint without having to have Windows Server installed.) Services such as Microsoft Office SharePoint Server (MOSS) provide additional functionality and features and are licensed accordingly.

SharePoint Family of Products:

Here are the current SharePoint products and technologies:

• Windows SharePoint Services 3.0 (WSS)
• Search Server 2008 Express
• Search Server 2008
• Forms Server 2007
• Microsoft Office SharePoint Server 2007 MOSS Standard
• Microsoft Office SharePoint Server 2007 MOSS Enterprise
• Microsoft Office Groove Server 2007
• Microsoft Office Project Server 2007
• Microsoft Office SharePoint Designer

SharePoint, as a collection of technologies, is not intended to simply replace a full file server or to be a single use solution. Instead, it is geared and positioned to play various roles in the business and enterprise environment. Microsoft markets these vectors as Collaboration, Processes, and People.

The SharePoint user interface is a web interface accessed through a browser. While all browsers are supported, only Internet Explorer is fully integrated and able to utilize the full functionality of a SharePoint Solution.

SharePoint sites are functionally ASP.NET 2.0 web applications, which are served using IIS and use a SQL Server database as a data storage back end. All site content data, such as items in document libraries and lists, are stored within an SQL database named by default as "WSS_Content_[ID]".

Microsoft Search Server:

Microsoft Search Server (MSS) is an enterprise search platform from Microsoft. It builds on the search capabilities of Microsoft Office SharePoint Server. MSS shares its architectural underpinnings with the Windows Search platform for both the querying engine as well as the indexer. MOSS search provides the ability to search metadata attached to documents.

Microsoft has made Microsoft Search Server available as Search Server 2008, released March 2008. A free version, Search Server 2008 Express, is also available. The express edition features the same feature set as the commercial edition, including no limitation on the number of files indexed. However, it is limited to a stand-alone installation and cannot be scaled out to a cluster.

Microsoft Office SharePoint Designer:

Microsoft Office SharePoint Designer is a free WYSIWYG HTML Editor that administrators can use to customize the design of the SharePoint site and that end users can use in designing workflows. SharePoint Designers is the successor to Microsoft FrontPage and replaces it.

1. To avoid SQL Injection, replace all SQL Commands with parameterized queries or stored procedures (using LINQ to SQL exclusively will also totally eliminate SQL Injection).

2. To avoid packet-sniffing and session hijacking, always use https when sending cookies

3. To avoid Cross-Site Scripting problems, use httpOnly when setting cookies

 Here is a summary of the information in the articles I read that led me to the above “cheat sheet”:

=========================================

How to Prevent SQL Injection:

Explanation of Vulnerability: SQL Injection occurs when someone enters a part of a SQL Command as part of user input, querystring, or cookie.  For example, if person enters " or '1' = '1' in a password textbox, that might be interpreted as part of the sql command and cause the password to always be accepted.

 Approach #1: Replace SQL Commands with Parameterized queries

 One way to prevent sql injection 100% of the time is by replacing all SQL Commands with parameterized queries.  The queries can be stored procedures, but they do not have to be. Stored procedures are a little more efficient because they optimize execution plan, but parameterized queries that are not stored procedures are also safe with regard to sql injection.  The information in the parameterized fields is always treated as a literal by sql server and can never be executed as part of the sql instruction itself.  Using parameterized queries in all SQL Commands in an application prevents sql injection through: 1) user input; 2) query strings; and 3) cookies. The work involved in implementing it would require that every SQL Command that uses input from user, query string, or cookie be converted to parameterized query.

 Approach #2: Replace SQL Commands with LINQ to SQL

 LINQ to SQL, when used exclusively for data access, eliminates the possibility of SQL injection in your application for one simple reason: every SQL query that LINQ executes on your behalf is parameterized.

 Approach #3: Create "Blacklist" of special characters and words

 Here is a shortlist of five predefined entities in xml that people often try to santitize (remove) from user input:

1. quot "
2. amp  &
3. apos '
4. lt   <
5. gt   > 

Here is another example blacklist:

public static string[] blackList = {"–",";–",";","/*","*/","@@","@",
                                     "char","nchar","varchar","nvarchar",
                                     "alter","begin","cast","create","cursor",
                                     "declare","delete","drop","end","exec","execute",
                                     "fetch","insert","kill","open",
                                     "select", "sys","sysobjects","syscolumns",
                                     "table","update"};

Two drawbacks of SQL Injection "Blacklists" of special characters or words: 

1) Blacklisted words and characters change over time. For example, => (lambda) is new C# expression that was recently introduced.

2) Frustrates users trying to enter real data. For example, a user will become frustrated if the quote mark they enter in a textbox mysteriously vanishes each time they enter it.

How to Prevent JavaScript Injection:

 Explanation of the Vulnerability: If someone enters javascript in a textbox they can possibly attach an event to a submit button that will execute whenever anyone presses submit. The event can be used to send private information to the attacker.

 JavaScript injection is automatically prevented by the Request Validation feature of ASP.NET, which is always set to being on by default.

How to Prevent Cookie Vulnerabilities:

1. Only use https when sending cookies

Explanation of the Vulnerability: Packet Sniffing –  Hijacking Cookies that are sent over sessions that are not https

Cookies can be stolen via packet sniffing in an attack called session hijacking. Traffic on a network can be intercepted and read by computers on the network other than its sender and its receiver (particularly on unencrypted public Wi-Fi networks). This traffic includes cookies sent on ordinary unencrypted http sessions. Where network traffic is not encrypted, malicious users can therefore read the communications of other users on the network, including their cookies, using programs called packet sniffers.

This issue can be overcome by securing the communication between the user's computer and the server by employing Transport Layer Security (https protocol) to encrypt the connection. A server can specify the secure flag while setting a cookie; the browser will then send it only over a secure channel, such as an SSL connection.

However a large number of websites, although using encrypted https communication for user authentication (i.e. the login page), subsequently send session cookies and other data over ordinary, unencrypted http connections for performance reasons. Attackers can therefore easily intercept the cookies of other users and impersonate them on the relevant websites or use them in a cookiemonster attack.

2. Always Use httpOnly when setting cookies

Explanation of the Vulnerability: Cross-site scripting (xss) attacks on cookies

Your own site may be secure from Javascript injection, but another web site may not be. If a user goes to your site and logs in and then goes to a bad site while logged in to your site.  The bad site can execute javascript that will send the cookies for your good site to the attacker.  The way to prevent this is by using HttpOnly flag when setting cookies.  HttpOnly says that the cookies from your good site can only be accessed from the server – not from javascript that executes on the client.  Since the cookies cannot be read from client-side javascript, the cookies are safe from cross-site scripting even when someone visits a bad site while logged into your good one.

The Albert Einstein robot in this video was not developed with Microsoft Robotics Developer Studio, but it does serve to point the direction robotics is heading. (All the other videos in this post do deal with robots that are supported by Microsoft Robotics.)

Note: If you want to "deep dive" into robotics concepts and theories, you may want to check out Stanford's Introduction to Robotics, which is a 16 part video series taught by Oussama Khatib.

Four Components of Microsoft Robotics Developer Studio:

An ICreate Robot in a Visual Simulation Environment

• CCR (Concurrency and Coordination Runtime) – makes asynchronous programming simple. The CCR makes it simple to write programs to handle asynchronous input from multiple robotics sensors and output to motors and actuators. With the use of CCR, we don’t need to do any manual threads management. This can be especially useful in handling concurrency and partial failure. CCR has a failure handling mechanism called Causalities. This is basically a generalization of Try / Catch for multiple threads. But this is for many machines and processes working in synchronous fashion. This is the base of Robotics architecture by Microsoft. You can even use this component for the applications running on a PC instead of a robot. CCR is available in the form of a dynamic link library which may be used by any .net language.
• DSS (Decentralized Software Services) is the services architecture, and it is a companion to CCR. This is based on Service Oriented Architecture. This provides the ability to write applications which are highly distributed and modular. This means you can execute your code in the processing work horses and use anywhere in the distributed environment. The DSS makes it simple to access, and respond to, a robot’s state using a Web browser or Windows-based application. This provides for real-time monitoring of robotics sensors and real-time response to motors and actuators.
• VPL (Microsoft Visual Programming Language) is a visual programming tool that is used for creating and debugging robot applications, web-based and windows-based interfaces.
• VSE (Visual Simulation Environment) allows one to simulate the behavior of robots in a virtual world using NVIDIA PhysX technology (3D engine) that includes advanced physics.

The runtime environment consists of two components: the CCR and the DSS. The runtime is based on a lightweight REST-oriented services model. Making it REST based has made the services and applications to be independent of each other. They may be on the same machine or distributed across different machines connected through any means. When we say REST based, this means that the resources should be available by query strings. These services are available as resources to the other services, applications or User Interfaces. This is actually how Microsoft is able to promise low coupling between services. The Runtime supports from 8-bit to 32-bit robots. These robots may range from Toy Robots to Industrial Robots.

Microsoft Visual Programming Language enables anyone to create and debug robotics programs very easily. Just drag and drop blocks that represent services, and connect them. It is also possible to take a collection of connected blocks and reuse them as a single block elsewhere in the program. VPL follows the Observer Pattern. This means that it is not based on Control flow but on data flow which enables some program elements to get executed when some data arrives. VPL provides a model-driven approach to develop and orchestrate services.

MRDS: Simulated Robot and Environment

Six Key Features of MRDS

• Reuse Modular Services Using a Composable model

Build high-level functions using simple components, providing for reuse of code modules as well as better reliability and replaceability. For example, a lower-level sensor service could be integrated into a navigation service.

• Scalable and Extensible Platform

The RDS programming model can be applied to a variety of robot hardware platforms, enabling users to transfer their skills across multiple platforms. The programming interfaces can be used to develop applications on single or multi-core processors.

• Easily extend Microsoft Robotics Developer Studio Functionality

Third parties can extend the functionality of RDS by providing additional libraries and services. Hardware or software vendors can make their products easily compatible with RDS.

• Supports both remotely connected (PC-based) and robot-based (autonomous) application scenarios

Remotely connected scenarios enable communication from a PC to the robot through a serial port, Bluetooth®, 802.11 (WiFi), or RF modem. Programs can also execute natively on PC-based robots running one of the Microsoft Windows operating systems, enabling fully autonomous operation.

• Develop using a wide range of programming languages

MRDS allows you to access the runtime services using the following programming languages: C# and Visual Basic .NET, JScript, and IronPython

• Microsoft Robotics Developer Studio allows one to use various packages to add other services to the suite.
  • Soccer Simulation
  • Sumo Competition by Microsoft
  • a community-developed Maze Simulator which is a program to create worlds with walls that can be explored by a virtual robot

Those other services include:

Sample Applications:

• Princeton University's DARPA Urban Grand Challenge autonomous car entry was programmed entirely with MRDS.
• In 2008 Microsoft launched a simulated robotics competition named RoboChamps using MRDS, four challenges were available : maze, sumo, urban, and mars rover. the simulated environment and robots used by the competition were created by SimplySim and the competition was sponsored by KIA Motors.

Supported Robots:

• Aldebaran Robotics
• CoroWare
• Lego Mindstorms NXT
• KUKA Robotics Educational Framework
• Robosoft's robots
• Segway
• RoboticsConnection
• RoombaDevTools by RoboDynamics
• WowWeeRoboSapien via the USB-UIRT device
• e-nuvo WALK

Background: C# is a simple, modern, general-purpose, object-oriented programming language. Anders Hejlsberg is the chief architect for C#. It has an object-oriented syntax that evolved out of C++. The most recent version of the language is 3.0, and it was released in conjunction with the .NET Framework 3.5

In 1999, when Anders Hejlsberg formed a team to create the language, they originally planned to call it COOL (C-like Object Oriented Language). However, there were copyright problems with that name, and it was renamed C#. C Sharp in music means a half of a step higher in pitch. In programming, C Sharp indicates that this is an outgrowth of C++.

Anders Hejlsberg has repeated said that flaws in most major programming languages (e.g. C++, Java, Delphi, and Smalltalk) drove the fundamentals of the Common Language Runtime (CLR), which, in turn, drove the design of the C# programming language itself.

Versions:

• C# 1.0 – introduced 2000 / released January 2002
• C# 1.2 – released April 2003
• C# 2.0 – released November 2005
• C# 3.0 – released November 2007
• C# 4.0 – in development

Design Goals:

• C# is intended to be a simple, modern, general-purpose, object-oriented programming language.

The language should provide support for:

• strong type checking
• array bounds checking
• detection of attempts to use uninitialized variables
• automatic garbage collection
• Software robustness
• durability
• programmer productivity
• The language is for developing software components suitable for deployment in distributed environments.
• Source code portability and programmer portability are important, especially for those programmers already familiar with C and C++.
• internationalization is very important.
• C# is intended to be suitable for writing applications for both hosted and embedded systems

Distingushing Features of C#

• There are no global variables or functions. All methods and members must be declared within classes. Static members of public classes can substitute for global variables and functions.
• Local variables cannot shadow variables of the enclosing block, unlike C and C++.
• C# supports a strict Boolean datatype, bool. Statements that take conditions, such as while and if, require an expression of a boolean type. While C++ also has a boolean type, it can be freely converted to and from integers
• In C#, memory address pointers can only be used within blocks specifically marked as unsafe, and programs with unsafe code need appropriate permissions to run.
• Managed memory cannot be explicitly freed; instead, it is automatically garbage collected.
• Multiple inheritance is not supported, although a class can implement any number of interfaces.
• C# is more typesafe than C++.

Background: ASP.NET is a web application framework developed by Microsoft. The framework makes it possible for programmers to build dynamic web sites, web applications and web services. ASP.NET is built on the Common Language Runtime (CLR). The CLR allows programmers to write ASP.NET code using any supported .NET language.

After the release of Internet Information Services 4.0 in 1997, Microsoft began researching possibilities for a new web application model that would solve common complaints about ASP, especially with regard to separation of presentation and content and being able to write "clean" code. Mark Anders, a manager on the IIS team, and Scott Guthrie, who had joined Microsoft in 1997 after graduating from Duke University, were tasked with determining what that model would look like.

The initial version was called "XSP", but the "X" did not actually stand for anything. It was decided to build the new platform on top of the Common Language Runtime (CLR), as it offered an object-oriented programming environment, garbage collection and other features that were seen as desirable features that Microsoft's Component Object Model platform didn't support.

XSP was renamed to ASP+ as it was seen as being the successor of Active Server Pages. Then, in 2000, it was renamed to ASP.NET to emphasize that it rested on the underlying .NET framework.

Versions: ASP.NET 1.0 was released in January of 2002. 2.0 was released in November 2005, and 3.0 in November 2006. The current version is 3.5, and it came out in November 2007. 4.0 is scheduled to released in the next few months.

Background: ADO.NET is an outgrowth of ADO (ActiveX Data Objects) technology. ADO relied on COM objects whereas ADO.NET is based on the .NET Framework. ADO.NET does not replace ADO for the COM programmer; rather, it provides the .NET programmer with access to relational data sources, XML, and application data.

Purpose: ADO.NET is used to access data and data services. The data is usually a relational database, but it does not have to be.

Architecture: ADO.NET is part of the Base Class Library. ADO.NET consists of two parts:

• Data Provider

Data providers provide access to the data source. The data source can be: SQL Server, Oracle, or OLEDB (ex. Access). Each data source has its own set of provider objects, but they all include these common utility classes:

• Connection – Provides a connection to the datasoure. It is like a phone line that connects the application to the database.
• Command – Command is used to perform some action (add, update, delete, select, etc.) on the database.
• Parameter – This is a variable in the command.
• DataAdapter – The data adapter provides a bridge between the data source object and the data set object.
• DataReader – Allows you to access records sequentially, one record at a time.
• Datasets

DataSets represent in-memory relational databases. Datasets represent a schema that can contain one or more tables and the relationships between the tables.

• DataTable represents a single data table that is made up of rows and columns.
• DataView is an overlay for a datatable that can contain a sort and a filter.
• DataRelation is a relation between tables.
• Constraint describes an enforced property of the database.

A DataSet is populated from a database by a DataAdapter whose Connection and Command properties have been specified. A DataSet can save its contents to XML, or populate itself from XML, making it very useful for web services and distributed computing.

Related posts brought to you by Yet Another Related Posts Plugin.]]> Here is a collection of 10 premium video tutorials on .NET Remoting by Learn Visual Studio. In order to view the videos, you need to become a member of Learn Visual Studio.

Here are a few things you need to understand about remoting:

• Purpose: .NET Remoting makes it possible for software components to interact across application domains.
• History: .NET Remoting is an API that was introduced with .NET Framework 1.0 in 2002 to improve upon earlier technologies for interprocess communication.
  • In 1990, OLE (Object Linking and Embedding) was developed;
  • in 1993, COM (Component Object Model) was created
  • and in 1997, this was advanced to DCOM (Distributed Component Object Model) and renamed to ActiveX;
  • in 2000, COM+ came into being;
  • in 2002, .NET remoting was introduced;
  • in 2007, WCF technologies were implemented in NET Framework 3.0
• Historical Problems: DCOM had its problems as it relied on proprietary format. Also there were problems of communication between COM objects spread across firewalls. .NET Remoting eliminated these difficulties by supporting various transport and communication protocols and by being adaptable to diverse network environments.
• General Concepts: .NET Remoting allows an application to make an object (which is called a "remotable object") available across remoting boundaries. This can include different appdomains, processes or even different computers connected by a network. The .NET Remoting runtime hosts the listener for requests to the object in the appdomain of the server application. At the client end, any requests to the remotable object are proxied by the .NET Remoting runtime over Channel objects, that encapsulate the actual transport mode, including TCP streams, HTTP streams and named pipes. As a result, by instantiating proper Channel objects, a .NET Remoting application can be made to support different communication protocols without recompiling the application. The runtime itself manages the act of serialization and marshalling of objects across the client and server appdomains.
• Architecture: See Architecture section of this msdn article on Improving Remoting Performance

Threads Running within a Process

Here is a collection of 5 premium video tutorials on .NET Framework by Learn Visual Studio. In order to view the videos, you need to become a member of Learn Visual Studio.

Here are a few things you need to understand when working with threads:

• Threads are  light-weight processes that make multitasking within a single application possible.
• System.Threading is the base class used for threading
• Programmers don't have to manage any threads explicitly – Threads are managed under the Common Language Runtime.
• When using threading with the combination of components, it is a good idea to use explicit definition and management of the thread.
• Threads are used in situations where you want to perform more then one task at a time.
• In the case of Synchronization, you may have to restrict the access to the resource to one thread at a time because you have limited amount of resourses, . In this situation, you may implement locking on the threading to over come the scenarios.
• An apartment is a logical container within a process and is used for objects that shares the same thread-access requirement. Objects in the apartment can all receive method call from any object in any thread in the apartment. A managed object (object created within CLR) is responsible for thread safety.
• Threads can be used in situations where we must wait for an event such as user input, a read from file, or receipt of data over the network. Freeing the memory to turn it a safe, and it makes our program to appear to run more quickly.

.NET Framework Versions

Here is a collection of 4 video tutorials on .NET Framework by Learn Visual Studio. You need to become a member of Learn Visual Studio to view the videos.

The Microsoft .NET Framework is a software framework that includes a library of coded solutions to common programming problems and a virtual machine that governs the execution of programs written for the framework.

The .NET Framework consists of these two components:

• Base Class Library
• CLR (Common Language Runtime)

The framework's Base Class Library provides the following features:

• user interface
• data and data access
• database connectivity
• cryptography
• web application development
• numeric algorithms
• network communications

Programmers combine the Base Class Library with their programs to simplify the coding tasks.

Programs written for the .NET Framework execute in a software environment that is known as the Common Language Runtime (CLR). The CLR functions as a virtual machine so that programmers do not need to worry about the capabilities of the specific CPU that will execute the program.

The CLR also provides other these other important services:

• security
• memory management
• exception handling

Version 3.0 of the .NET Framework is included with Windows Server 2008 and Windows Vista. The current version of the framework can also be installed on Windows XP and the Windows Server 2003 family of operating systems. A reduced version of the .NET Framework, the .NET Compact Framework, is also available on Windows Mobile platforms, including smartphones. Version 4.0 of the framework was released as a public Beta on 20 May 2009.
