.NET is a development framework created by Microsoft that allows developers to create applications for various platforms like web, mobile, desktop, games and more. It provides a common language runtime (CLR) that compiles source code into an intermediate language (MSIL) and handles execution. .NET has gone through multiple versions adding new features like generics, LINQ, parallel computing and supports programming languages like C#, VB.NET and C++. It provides object-oriented capabilities, automatic memory management, security, exception handling, reflection and cross-language integration capabilities. Assemblies are reusable modules that can be shared between applications.

1. About .NET

2. Introduction:
• In the present business advancement methodology and
arrangement improvement exercises Microsoft .NET innovation
is assuming a fundamental part.
• Microsoft has made a world class best improvement suit for
the designers who create normal business and worldwide
subject related arrangements utilizing the product building.
• Microsoft built up the .NET stage to meet a stage free, dialect
nonpartisan and system situated improvement apparatuses.
• The arrangements grew by utilizing .NET are adaptable and
dependable

3. Accumulation and Execution
• In .NET stage the accumulation and Execution is taken care by
the CLR (Common Language Runtime). CLR takes after the
accompanying grouping of steps when a .NET source code
composed utilizing C#/VB.NET/VC++. NET/VJ#
• A source code written in C#/VB.NET/VJ#/VC++.NET is ordered
and Microsoft Intermediate Language (MSIL) is produced
• The MSIL is ordered by the .NET CLR's JIT compiler and results
the local executable code at runtime.

4. .NET Versions
• .NET has diverse forms right from the beginning of its
development. .NET 1.0, 1.1, 2.0, 3.0, 3.5 and most recent 4.0
• In 1.0 the fundamental .NET improvement API are given
• In 1.1 Built-In backing for Mobile ASP.NET segments is presented
• In 2.0 the Generics is presented
• In 3.0 the Service model is presented
• In 3.5 the LINQ is presented
• In 4.0 Parallel Computing is presented
• With each rendition numerous new highlights are added to the
.NET improvement environment and made it more dependable
advancement instrument

5. Article Oriented:
• .NET is item situated. It bolsters the article arranged ideas like
Object Initialization, Inheritance, and Polymorphism.
Programmed Garbage gathering:
.NET has the asset administration framework by utilizing Garbage
accumulation where the issues or Memory break are over come.
System.GC() is the API gave in .NET to conjure the Garbage Collector
unequivocally in the system.
Security:
.NET gives the security design to the application by its System. Security
name space.
Multi Threading:
.NET gives office to create application with Multi threading where
numerous procedure can be executed no concurrently to make
application more proficient and dependable

6. Special case Handling:
.NET gives the system of taking care of exemptions in the application
at runtime. One can characterize and utilize the custom exemptions
with the assistance of the System. Exception class. .NET has
predefined framework special cases like FileNotFoundExcepotion,
Argument Exception, ArrayOutofBoundsException and so on.
Reflection:
.NET has the highlight called Reflection utilizing which the .NET
executable can be perused with its metadata. The sorts in the
executable can be know by utilizing this highlight. The .NET gatherings
can be created runtime and examined at runtime by utilizing this
highlight.
Cross Language Integration:
.NET backings various dialects like C#, VB.NET, VC++.NET, and VJ#. An
answer can be created utilizing any of these dialects. Indeed, even
parts grew in one dialect can be devoured by other dialect
applications.

7. Congregations:
.NET Assemblies are proficient modules that can be used in the
applications. There are three sorts of congregations Private, Shared
and Satellite. Private gatherings can be utilized by the application just.
Imparted gatherings can be put in Global Assembly Cache (GAC) and
be imparted by different applications. Satellite congregations used to
impart the asset sorts.
Confinement:
.NET applications can be produced for a distinct nearby assets based
execution situations. Case in point Chinese, Japanese and so on.
Now a days lot of .NET training classes and .NET online training are
also available.
