Assemblies are the building blocks of the .net framework.
An assembly is a collection of types and resources that are building to work
together and form logical units of functionality. An Assembly problem the
common language run time the information it needs to be aware of type
implementation, To the run time a types does not exist outside the content of
Every project after compilation will generate an output
the known as assembly .The assembly name as same as project name. The assembly
corresponding to a project will present under bin/debug folder of the project. Assembly
is known as units of deployment because once the project development is
completed what we carry and install on the client system is assembly files
only. The extensions of the assembly .dll (dynamic link library) and .exe (executable).
are two types:
1. Private Assembly
2. Shared Assembly
Private Assembly: By
default every assembly are private. If reference of these assemblies added to
any project, a copy of the assembly is created and given to the project to each
project maintain private copy of the assembly.
Shared Assembly: If
we intend to use an assembly among several application private assembly are not
feasible. In such we can install it into a centralized location known as a
global assembly (gac). Each computer common language runs time machine-wide
code. The global assembles Cache
stores assemblies specially designed to be shared by several application on the
Name: Assembly deployed
in the global assembly cache must have a strong name. When assembly is added to
the global assembly cache, integrity checks are performed on all files. Strong name consists to the
assembly’s identity- Simple text name, Version and public key.
Name: It was the name of an
assembly used for identification. Every assembly by default has name.
Version: Software’s maintain
versions for discrimination changes from time to time.
Public Key: Gac contains multiple assembles in it, to
identify to each assembly it will maintain a key value for the assembly known
as public key, which should be generated by us an associated was the assembly
to make it strong.
