GAC Manager is an open source project that comes in two parts - a fully functional application to manage the Global Assembly Cache on your computer, and a C# API to allow you to manage the GAC yourself. The GAC Manager Application

The GAC Manager Application is designed to offer fast access to the GAC. A lean application lets you search for assemblies quickly and get important information you need.

The C# API provides all of the functionality required by the GAC Manager Application and is offered to allow developers to write their own applications that work with the GAC.

A description of how to work with the API is available in the following article:
