# Global Assembly Cache (GAC) in .Net

In this blog, I’m explaining about GAC in .Net\

\
Each computer on which the [common language Runtime](https://www.mindstick.com/articles/16/common-language-runtime) (CLR) is installed has a machine-wide code cache called a ‘[Global assembly](https://www.mindstick.com/forum/158570/what-is-the-global-assembly-cache-gac-and-how-is-it-used-in-dot-net) Cache’. The Global Assembly cache (GAC) enables you to share assemblies across numerous applications.

The GAC is automatically installed with the .NET runtime. The global assembly cache is located in ‘Window/ WinNT’ [directory](https://www.mindstick.com/forum/226/how-to-get-application-directory-using-c-sharp-csharp) and inherits the directory’s [access control](https://www.mindstick.com/forum/158579/how-does-the-dot-net-framework-provide-support-for-security-and-access-control) list that administrators have used to protect the folder.
