Daniel hat mich heute auf das Tool AddInSpy aufmerksam gemacht, welches Entwickler beim erstellen von VSTO Add-Ins unterstützt.

Summary: AddInSpy is a diagnostic tool which discovers all registered Microsoft Office add-ins on a computer, and reports the maximum possible information about these add-ins. The tool works with all versions of all Microsoft Office applications that support COM add-ins, and all types of COM add-ins.

AddInSpy bietet eine Übersicht über folgende Informationen...

• Whether the host application is running, and whether the add-in is loaded.
• The type of each add-in: VSTO, managed non-VSTO, native.
• FriendlyName, ProgID, CLSID and LoadBehavior of the add-in.
• Manifest path, assembly path, and assembly strongname.
• Registry hive (HKCU or HKLM) where the add-in is registered.
• CLR version the add-in was built against.
• VSTO runtime version used by the add-in.
• Installed date, and publish version.
• Which extensibility interfaces the add-in implements for Ribbon, custom taskpane, etc (including via VSTO wrappers).
• Whether the add-in exposes itself for automation through the COMAddIns collection of the Office host application.
• Whether the add-in is in the disabled items list for the current user, for each selected Office host application.
• Whether the add-in is registered as the provider for any custom form regions.
• Context information: machine name, user/domain name, OS details, VSTO environment variables.

...und listet diese übersichtlich auf:

Dadurch erspart man sich viel "gesuche" in der Registry etc. Eine ausführliche Anleitung zu dem AddInSpy befindet sich im MSDN.
