What is .NET ? .Net framework Architecture ? Component of CLR

 What is .net ?

Microsoft .Net

• .Net is product of Microsoft.

• .Net is Network based framework & under in .Net all object oriented programming language supported.

• .Net is collection of object oriented programming languages , technology , Database server and server database.

• .Net is a framework not a language. 

• NGWE : Next Generation Windows Services.

• .Net is a platform for developing application software.

• .Net platform or framework apart from many other development Environment Such as IDE. 

.Net framework Provide the Some Component 

1. Languages :  i) .Net framework support the 70+ object oriented languages
2. CLS : Common Language Specification
3. CTS : Common Type System
4. Application (console , windows , web application)
5. ADO.Net : .Net Remoting
6. Base Class Library / Framework Class Library (BCL/FCL)
7. CLR : Common Language Runtime

.Net framework Architecture 

.net framework architecture 

• CLS : set of rules & object oriented features.

• CTS : Contain class or structure and all the database. Each and Every datatype is a itself class or structure.

• ADO.net : This technology to interact with DATABASE and .NET application.

• BCL : It's a collection of class library.

****** Namespace - Namespace is a collection of logical classes. Namespace contain class ,structure , interface namespace are use to avoid naming collection. 

.net support 30,000+ BCL Using system.Data Its a namespace , in this namespace are collected more class library. in this namespace Using System is a root name & data is a class.

• CLR : It's a Runtime Environment in which all .net application are run. CLR is a core part of .net Architecture.

    i) VS.Net : It's a IDE where we can develop the .Net application.

   ii) .Net : It's a integrated component of operating system which is support development & execution of NGWS and web services and XML services.

Component of CLR 

• Class loader : It's a responsible for loading information in to memory.

• Code Manager :  Is responsible for loading all code into memory. there are Two type of code.                i) Manage code : Under the code management.  ii) Unmanaged code : Does't under code management.

• Garbage collector : It's responsible for allocation memory, De-location memory , variable , objects.

• Security manager : Two type of security.                                                                                                                      i) Role base security        ii) Code access security

• Exception manager : Are unusually code in a program run time error to use in exception.

• Thread manager : There is process of Multitasking & Multi-threading.

• Just-In-Time compiler : Convert MSIC code to CPU understand language or MSIC means platform freedom.
