.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)

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.

The .NET framework is a software component that is included with Microsoft Windows operating system, or it can be downloaded separately and added to it. NET Framework 3.0 was originally called WinFX. It is the current version of the NET Framework, and it is more of an add-on to NET Framework 2.0 than a whole new framework, as the major components of the 2.0 version are included within 3.0.

There were two main components of the Net Framework 2.0.

1. Framework Class Library – contains the building blocks (bricks) that are used to build all other classes.

2. Common Language Runtime (CLR) – This is similar to Java's Virtual Machine, in that is unique to each operating system and acts as middle person between an intermediate language and the language that the operating system speaks.

In general, the NET Framework acts as an intermediary between .NET applications and the operating systems that they execute on. It is as if .NET application languages are written in English (Visual Basic.NET), Spanish (C#), and French (J#) and the operating systems are written in Greek (Windows), Hebrew (Linux), and Latin (Mac). In order for the hardware to understand what the applications are trying to do, the modern languages (English, Spanish, and French) are first translated (compiled) into assemblies (or executables) in a common language of the Middle Ages, say Middle English. This common language(Middle English) is called the Common Intermediate Language (CIL) in the Microsoft world.

The Common Language Runtime (CLR) component of the NET Framework takes this intermediate language and translates it into the corresponding words that each of the operating system understands. Thus, there is a different Common Language Runtime Component for each operating system. At the present time, the only operating system that has a complete Common Language Runtime component for it is Windows, but there is a project called Mono that is attempting create an open source common language runtime component for Linux, Solaris, Mac OS, and Windows. When that occurs, .NET applications will truly become "platform independent."

The .NET Framework is used to:

1. Provide Huge Chunks of Pre-written Routines – The principle advantage of the NET framework is that it takes many of the operations(security, memory management, exception handling, etc.) that are performed over and over again, and allows them to only be coded once.

2. Provide Platform Independence – .NET languages (Visual Basic, C#, J#) are compiled to an intermediate state (Common Intermediate Language), and then, the Common Language Runtime component translates that into a language that the specific operating system can understand. This allows one to code in the high-level language of Visual Basic or whatever without having to worry about what machine it will end up executing on.

3. Provide Language Independence The Common Type System (CTS) is used to insure that all .NET langauges use the same types for descriptions for fields. These languages also have access to the Base Class Library (BCL) to reduce the amount of low-level coding that must be done in each language.

4. Provide Simplified Deployment – Special care must be taken to make sure that new installations of software do not interfere with previously installed versions. The .NET Framework is designed to help avoid these types of problems from occurring.

Four New Components Added With NET Framework 3.0

1. Windows Presentation Foundation (WPF – code-named Avalon) – As the name implies, this component deals with the "presentation" layer of net applications. This the coolest new feature for most users. It uses XML and vector graphics to present 3-D images, allowing rotation, panning, etc.

2. Windows Communication Foundation (WCF – code-named Indigo) – This component provides a service-oriented messaging system which allows programs to interoperate locally or remotely similar to web services.

3. Windows Workflow Foundation (WWF – Workflow) – Allows one to use workflows to automate business tasks by connecting code to business model diagrams.

4. Windows CardSpace (WCS – code-named InfoCard) – This component stores a person's digital identities to help integrate the user's experience as they go from one web site or application to another. This helps to eliminate the need for so many user ids and passwords so that a person can seemlessly move from one task to another.

.NET 3.0 – A "View from space"…-NetFX…

Here is a 4-minute video that gives a high-level introduction to NET Framework 3.0. It gives an interesting overview of the four new components (November 16, 2006).

Chris Bowen: Introduction to the .NET Framework

Here is a hour and twenty-five minute in depth look at the four new components of NET 3.0 by Chris Bowen (Apr 18, 2007). Unfortunately, you cannot see much of the whiteboard on the video, but you can hear what he has to say if you are interested in getting into more of the details.

WinFX in Financial Services

Here is an six-minute video example where Lab49 founder Daniel Chait demonstrates how they have used the 3-D features of Windows Presentation Foundation to help them understand the financial markets.

WPF Controlled by external sensors

Here is a six-minute video of how Brian Warner demonstrates that external sensors can be used to control WPF (February 05, 2007).

Ink Features in WPF

Here is a five-minute video demonstration of how WPF enhances Inking with tablet PCs (September 12, 2006).

Intro to WPF Part 1: XamlPad

A five-minute tutorial that introduces you to XAML (Mar 30, 2006).

My First Workflow

This 15-minute video by Stephen Thomas is an excellent introduction to workflows.

NET Framework 3.5

The next version of the NET Framework will be NET Framework 3.5. It is currently in beta testing. NET Framework 3.5 includes a entirely new version of the CLR. The CLR will be 3.0, as opposed to the 2.0 version that was used with NET Framework 3.0. Other new features will be LINQ queries, extension methods, and anonymous types with static type inference.

Final Note: If you would like to try to use some of the NET Framework 3.0 features, you must first download the NET Framework 3.0 software from Microsoft. Then, if you are using Visual Studio 2005 or the Express Editions of 2005, you have to download Visual Studio 2005 extensions for .NET Framework 3.0 (WCF & WPF)

.NET Framework Definition

The .NET applications and services operate within the .NET Framework (pronounced "dot net framework"). .NET applications do not directly access the operating system. Instead, they use the .NET framework, and the .NET framework accesses the operating system and hardware. The framework consists of two components:

1. The .NET Framework Class Library, and
2. The Common Language Runtime (CLR )

The framework manages memory management, code execution, etc., and that is why .NET applications are called "managed applications."

The Common Type System makes sure that all .NET applications use the same data types.

The Visual Basic Compiler converts the humanly readable source code into an intermediate language. This intermediate language is also called Microsoft Intermediate Language (or MSIL), and it is contained in an assembly. Assemblies have either a .exe (executable) or .dll (class library) extension. The Common Language Runtime (CLR) converts the intermediate language into the native language needed by the operating system. This is what makes .NET applications platform independent. Currently the CLR is only available on Windows Systems, but someday CLR's could be developed of Unix and Linux. This would allow .NET applications to execute in these environments.
