Global Assembly Cache Comparer

From RudolfHenning:

Global Assembly Cache Comparer is an application to compare two assemblies. It is important to note that this tool does not make any changes to the GAC. It only reports the differences allowing you to make the decision what and how to change it. The tool does not use any fancy API or magic to retrieve information from the GAC's of remote machines. It basically does a file/directory scan which means you need administrative rights on the machines you are comparing (but then you would need admin rights anyway to get to the GAC). It then compares the information gathered by checking various properties of the assemblies like name, version, culture, and file size.
