Add and remove an assembly from GAC

.Net Assembly

The .Net assembly is a compiled code library used for deployment, versioning, and security. Assemblies residing in the Global Assembly Cache must adhere to a specific versioning scheme which allows for side by side execution of different code versions. There are two types of assembly, process assemblies (EXE) and library assemblies (DLL).

Each computer that .Net Framework is installed has a Global Assembly Cache, which is located in the Assembly folder in the Windows directory, normally C:\WinNT\Assembly. The Global Assembly Cache tool(Gacutil.exe) allows you to view and manipulate the contents of the global assembly cache.
