  Key Concepts: 
  Global Assembly Cache (GAC) is a repository of shared assemblies that are used by applications running on the SAP platform. It is a part of the OPU-DUE Duet Enterprise component of SAP. GAC stores assemblies specifically designated to be shared by several applications. 
  
  How to use it: 
  GAC is used to store assemblies that are shared by multiple applications. It is important to note that only assemblies that are explicitly designated as shared can be stored in the GAC. To add an assembly to the GAC, you must use the Global Assembly Cache Tool (Gacutil.exe). This tool can be used to install, uninstall, and list the contents of the GAC. 
  
  Tips & Tricks: 
  When adding an assembly to the GAC, it is important to ensure that the assembly has a strong name. A strong name consists of an assembly's identity—its simple text name, version number, and culture information (if provided)—plus a public key and a digital signature. This ensures that no two assemblies have the same name, which helps prevent DLL conflicts.
