n assembly performs the following functions: It contains code that the common language runtime executes. Microsoft intermediate language (MSIL) code in a portable executable (PE) file will not be executed if it does not have an associated assembly manifest. Note that each assembly can have only one entry point (that is, DllMain, WinMain, or Main).

Assemblies are the building blocks of .NET Framework applications; they form the fundamental unit of deployment, version control, reuse, activation scoping, and security permissions. An assembly is a collection of types and resources that are built to work together and form a logical unit of functionality. An assembly provides the common language runtime with the information it needs to be aware of type implementations. To the runtime, a type does not exist outside the context of an assembly.

Metadata provides the following major benefits: Self-describing files � Common language runtime modules and assemblies are self-describing. A module's metadata contains everything needed to interact with another module. Metadata automatically provides the functionality of IDL in COM, allowing you to use one file for both definition and implementation. Runtime modules and assemblies do not even require registration with the operating system. As a result, the descriptions used by the runtime always reflect the actual code in your compiled file, which increases application reliability.

Assemblies contain tables of metadata. These tables are described by the CIL specification. The metadata tables will have zero or more entries and the position of an entry determines its index. When CIL code uses metadata it does so through a metadata token. This is a 32-bit value where the top 8 bits identify the appropriate metadata table, and the remaining 24 bits give the index of the metadata in the table. The Framework SDK contains a sample called metainfo that will list the metadata tables in an assembly; however, this information is rarely of use to a developer.

In the past, a software component (.exe or .dll) written in one language could not easily use a software component written in another language. COM provided a step forward in solving this problem. The .NET Framework makes component interoperation even easier by allowing compilers to emit additional declarative information into all modules and assemblies. This information, called metadata, helps components to seamlessly interact.

The CLS provides following advantages: Access to Complete .NET Framework hierarchy. High level of interoperability within languages.(e.g. - C# Class can be inherit from a Visual Basic class). Component is accessible from any programming language that supports the CLS. All CLS-compliant languages can produce verifiable code so the type safety of code possible.

Metadata stores the following information: Description of the assembly. Description of types. Attributes.

What is Windows CardSpace (WCS, formerly �InfoCard�)? Windows CardSpace is a Microsoft .NET Framework version 3.0 (formerly WinFX) component that provides the consistent user experience required by the identity metasystem. It is specifically hardened against tampering and spoofing to protect the end user's digital identities and maintain end-user control.

Windows Workflow Foundation is the programming model, engine and tools for quickly building workflow enabled applications on Windows. It consists of a .NET Framework version 3.0 (formerly WinFX) namespace, an in-process workflow engine, and designers for Visual Studio 2005. Windows Workflow Foundation is available for both client and server versions of Windows.

What is Windows Communication Foundation (WCF)? Windows Communication Foundation (formerly code-named "Indigo") is a set of .NET technologies for building and running connected systems. It is a new breed of communications infrastructure built around the Web services architecture. Advanced Web services support in Windows Communication Foundation provides secure, reliable, and transacted messaging along with interoperability.

The Microsoft Windows Presentation Foundation provides the foundation for building applications and high fidelity experiences in Windows Vista, blending together application UI, documents, and media content, while exploiting the full power of your computer.

What is the Microsoft .NET Framework 3.0? The Microsoft .NET Framework 3.0 (formerly known WinFX), is the new managed code programming model for Windows. .NET Framework 3.0 is combines the power of the .NET Framework 2.0 with four new technologies

There are three types JIT (just-in-time) compiler. Those are as follows� * Pre-JIT compiler (Compiles entire code into native code completely) * Econo JIT compiler (Compiles code part by part freeing when required) * Normal JIT compiler (Compiles only that part of code when called and places in cache)

JIT (just-in-time) is a CLR�s (Common Language Runtime) compiler. The JIT Compiler function is responsible for compiling a method�s IL code into native CPU instructions. Because the IL(intermediate language) is being compiled "just in time," this component of the CLR is frequently referred to as a JITter or a JIT compiler.

.NET Framework supports all major programming languages. Some of them are as below� * ASP * ASP.NET * APL * C++ * C# * COBOL * Component Pascal and more

What is .NET Framework? The .NET Framework Includes the Common Language Runtime (CLR) and the .NET Framework class library. The CLR is a standard foundation for building a range of new applications, while the .NET Framework class library provides standard implementations of many new services for CLR-based applications. Among the technologies in the library are ASP.NET, which is the next generation of Active Server Pages;

The CLR is the layer of the .NET Framework that makes language independence work. Written mostly in Microsoft's new language, C#, the CLR provides services that any .NET program can use. Because of .NET's component architecture, software written in any language can call upon these services. Microsoft has also submitted a subset of the CLR to ECMA, the European information and communications standards organization. This subset is referred to as the Common Language Infrastructure (CLI). CLR provides following services:

Which are the main components of the .NET platform? The Microsoft .NET platform consists of the following product groups/ main components... Development tools A set of languages, including C#, VB.NET, J#, a set of development tools, including Visual Studio.NET (a suite of language-independent developer tools, a set of programming interfaces), .NET Framework (for building web and Windows applications, as well as web services), and Common Language Runtime, which is the execution engine for .NET Framework applications
