.NET Framework components 


  • Common Language Runtime(CLR) 
  • NET Framework Class Library 
  • Common Type System(CTS) 
  • Common Language Specification(CLS) 
  • Assemblies 
  • Windows Forms 
  • ASP.NET 
  • ActiveX Data Objects(ADO.NET) 
  • Windows Workflow Foundation(WF) 
  • Windows Presentation Foundation(WPF) 
  • Windows Communication Foundation(WCF)
  • Windows CardSpace
  • Language Integrated Query (LINQ)
  • Parallel Programming

Common Language Runtime (CLR)


 CLR ensures that the language-neutral development and execution environment that provides services to help "manage" application execution. 
  • A common runtime environment for all .NET languages. 
  • Use of Common Type System (strict-type & code-verification). 
  • Use of metadata for safe execution. 
  • Memory allocation and garbage collection.
  • Intermediate Language (IL) to native code compilers. 
  • Compiles MSIL code into native executable code. 
  • Security and interoperability of the code with other languages. 
CLR: Execution Mode

.NET Framework Class Library

  • The Class Library is a comprehensive, object-oriented collection of reusable types. 
  • The Class Library is organized in a hierarchy of namespaces. 
  1. Traditional command-line applications.
  2. Graphical User Interface (GUI) applications. 
  3. Applications based on the latest innovations provided by ASP.NET. 

Common Type System 

  1. Defines how types are declared, used, and managed in runtime. 
  2. Is also an important part of the runtime's support for crosslanguage integration. 
  3. Performs the following functions:
    1. Establishes a framework that helps enable cross-language integration, type safety, and high performance code execution. 
    2. Provides an object-oriented model that supports the complete implementation of many programming languages. 
    3. Defines rules that languages must follow, which helps ensure that objects written in different languages can interact with each other.

Common Language Specification (CLS) 

  • The CLS is a set of basic language features needed by many applications. 
  • The CLS rules define a subset of the Common Type System. All the rules that apply to the Common Type System apply to the CLS, except where stricter rules are defined in the CLS. 
  • The CLS helps to enhance and ensure language interoperability by defining a set of features that the developers can rely on to be available in a wide variety of languages. 
  • Components that adhere to the CLS rules and use only the features included in the CLS are said to be CLS-compliant components. 
  • Most of the members defined by types in the .NET Framework Class Library are CLS-compliant.

Assemblies

  • 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. 
  • They provide the CLR 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. 
  • An assembly can be Shared or Private:
    • A Private Assembly is available only to the application for which it is created. 
    •  A Shared Assembly is available to more than one (multiple) applications. Shared Assemblies are stored in the assembly cache (GAC) using the .NET utility Gacutil.exe or Regasm.exe.
