GAC stands for Global Assembly Cache.

It’s a special folder in .NET where shared assemblies (DLLs geometry dash lite) are stored so multiple applications can use the same version. Assemblies in the GAC must be strong-named (signed with a unique key), which helps manage versioning and avoid conflicts.

In short: GAC = centralized storage for shared .NET libraries with version control.

Global assembly cache

The global assembly cache stores assemblies specifically designated to be shared by several applications on the computer. You should share assemblies by installing them into the global assembly cache only when you need to. Assemblies deployed in the global assembly cache must have a strong name. When an assembly is added to the global assembly cache, integrity checks are performed on all files that make up the assembly. The cache performs these integrity checks to ensure that an assembly has not been tampered with, for example, when a file has changed but the manifest does not reflect the change. Use a developer tool called the Global Assembly Cache tool (Gacutil.exe), provided by the .NET Framework SDK or Use Windows Explorer to drag assemblies into the cache. To install a strong-named assembly into the global assembly cache At the command prompt, type the following command:gacutil IIn this command, assembly name is the name of the assembly to install in the global assembly cache.
