Easier way to add a DLL to the GAC

Often in BizTalk you’ll need to add assemblies to the Global Assembly Cache. In the past I had used a shortcut on my Quick Launch toolbar which opened the GAC, then I’d drop the assembly inside, but there is an easier way.

A registry key can be created which allows you to right click the DLL and “GAC it” in one click.

The text for the key is below; simply copy/paste it into notepad and save it as a registry file (.reg). Then double click the file to add it to the registry.

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\dllfile\shell\gacutil\command]
@="c:\\windows\\Microsoft.NET\\Framework\\v1.1.4322\\gacutil.exe /i \"%1\""


You can also download the Gacutil right-click key as a zip file here.
