.NET Framework Introducton

 

Definition:

.NET framework is a software development framework introduced by Microsoft for building different types of applications i.e. console applications, windows application, web applications and mobile applications etc. The first version of .Net framework was 1.0 which came in the year 2002.

 

.NET Framework Features / Characteristics:-


1. .NET stands for ‘Network enabled technology’.


2. Easy development of different types of applications.

3. Rapid application development.

4. Multi-Language support with asynchronous   programming.

5. Object oriented programming (OOPS) support.

6. Loosely coupling and extensible architecture.

7. Easy and rich debugging support.

8. Memory management and security.


.NET FRAMEWORK ARCHITECTURE:-

 

The .NET Framework is composed of four main components:

 

1.   Common Language Runtime (CLR).

 

2.   Framework Class Library (FCL).

 

3.   Core Languages (Win Forms, ASP.NET, ADO.NET, WEB API, LINQ and Entity Framework etc.)

 

4.   Programming Languages (C#, F#, VB.NET and Jscript).


1.  Common Language Runtime (CLR):-

The Common Language Runtime (CLR), the virtual machine component of Microsoft .NET Framework which responsible for loads and manages the execution of .NET programs. It converts the program into native code. It does exception handling, memory management, and garbage collection etc.

 

 

 

2.  Framework Class Library (FCL):-

.NET Framework Class Library is the collection of classes, namespaces, interfaces and value types that are used for .NET applications.

 

3.  Core Languages:-

.NET framework provides core languages like Win forms, ASP.NET, Web API etc. for building different types of applications and also provides ADO.NET, LINQ and Entity framework etc. for managing database connection.

 

4.  Programming Languages:-

.NET framework provides different types of programming languages like C#, VB.NET, F#, Jscript etc. for building different types of application like console and window applications etc.

CLR with advantages and architectures

Image
Common Language Runtime (CLR): CLR is the virtual machine component that manages the execution of programs written in any .NET framework programming languages i.e. C#, F#, VB.NET etc. CLR Features /Advantages:- 1. Heart of .NET framework. 2. Part of .NET Framework provided by Microsoft. 3. Memory management using garbage collector. 4. Exception handling and security with OOPS concepts. 5. Improved performance. 6. Language and architecture independency. 7. Multi-Thread support. 8. Convert MSIL code into native code using JIT compiler. 9. Extensible types. CLR ARCHITECTURE:   Components of CLR: 1.    CLR Loader: It loads all classes at runtime. 2. Garbage Collector:   It collect unused objects and deallocate objects  to reduce memory. 3.    Code Manager: manages code at runtime. 4.    Exception Manager: It handles exception at runtime.   5. JIT Compiler: ...
