.NET is a cross-platform, open source, and free
software framework that is used to run and
create various applications. Microsoft built it,
and Windows is the operating system.
Additionally, it is used to deploy and debug
code on a variety of.NET-based applications
utilising a variety of tools including libraries
and APIs.
3
What are the different languages that.NET
supports?
conceptserve _at_ConceptServe Technologies
.NET applications are written in a variety of
languages, including- -C which is a simple and
modern language. This programming language is a
type-safe language and is object oriented thus
used with .NET easily. -F which helps to write
code in a compact and easy way. -Visual Basic
is an approachable language and is used with
.NET to build type-safe applications.

an important component of the .NET framework. We
can use CLR as a building block of various
applications and provides a secure execution
environment for applications.
7
What is meaning by CLS?
conceptserve _at_ConceptServe Technologies
CLS stands for Common language specification
helps the developers to use the components that
are inter-language compatible with certain rules
that come with CLS. It then helps in reusing the
code in other .NET compatible languages.
8
What do you know about JIT?
conceptserve _at_ConceptServe Technologies
JIT is a compiler which stands for Just In Time.
It is used to convert the intermediate code into
the native language. During the execution, the
intermediate code is converted into the native
language.
9
What are managed unmanaged codes?
conceptserve _at_ConceptServe Technologies

• managed codes
• These are the codes that CLR or Common Language
  Run-Time manages. It is useful in managing
  memory with the help of garbage collection. The
  execution of managed codes is done using .Net
  framework and is necessary for its
  implementation.
• unmanaged codes
• These are all the codes that are not managed by
  the common language runtime or the CLR. It is
  independent of the .NET framework. Since the
  common language runtime does not handle it, the
  execution and management of memory are done
  independently.
