Gacutil is a command-line tool used primarily in the Microsoft .NET Framework development environment.
It stands for Global Assembly Cache Utility and is used for managing assembly files in the Global Assembly Cache (GAC).
The GAC is a central location provided by the .NET Framework to store and manage shared assemblies, making them accessible to multiple applications.
With the help of gacutil, developers can easily install, uninstall, list, and query assemblies in the GAC.
It is particularly useful when working with strong-named assemblies that need to be accessed by different applications on the same machine.
Gacutil allows developers to add assemblies to the GAC, using both the assembly file or the assembly name.
It also provides options to uninstall an assembly, verify the presence of an assembly in the GAC, and display a list of assemblies currently installed.
Gacutil supports specific command-line options like /i to install an assembly, /u to uninstall an assembly, /l to display the list of assemblies, and more.
This tool is primarily used during deployment, versioning, and management of assemblies, ensuring that the correct versions of assemblies are used by applications.
