Questions tagged [global-assembly-cache]

The global assembly cache is a .NET machine-wide code cache that stores assemblies designated to be shared by multiple applications.

More information about the global assembly cache (or GAC) can be found in the MSDN documentation: Global Assembly Cache.

There are two methods for deploying assemblies to the GAC:

  • Though an installer designed to work with GAC
  • Through the gacutil.exe utility from the Windows SDK

GAC assemblies are stored in the following directories on Windows:

  • .NET 4 and up: %windir%\Microsoft.NET\assembly
  • Prior versions of .NET: %windir%\assembly
