What is GAC? What are the steps to create an assembly and add it to the GAC?

The global assembly cache (GAC) is a machine-wide code cache that 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.

Steps

• Create a strong name using sn.exe tool eg: sn -k mykey.snk
• in AssemblyInfo.cs, add the strong name eg: [assembly: AssemblyKeyFile("mykey.snk")]
• recompile project, and then install it to GAC in two ways :

1. drag & drop it to assembly folder (C:\WINDOWS\assembly OR C:\WINNT\assembly) (shfusion.dll tool)
2. gacutil -i abc.dll
