AddinManager.Registry.Update failed when add new addin

What you do is correct and should work. If you are using the latest Mono.Addins version then maybe you found a bug. Try providing a console progress monitor in the Update call, with verbosity set to max. Maybe this will print an error you are missing.

Hi slluis, Thank you for your reply.
I searched this problem by Google, and I found this https://groups.google.com/forum/#!searchin/mono-addins/AddinManager.Registry.Update/mono-addins/QMTfoVWfSEc/j97DXSjC4gcJ , the same problem,
Today I test it again, unfortunately it only appear when release build.

Hi slluis, I can also see the same behavior with 1.3. The only workaround currently is to start the application once more, then the add-ins show up as expected.

In addition to my last comment, I just want to add more steps to reproduce. So I have an add-in registered for my application which works fine. I am doing an initialize with a followed update call during application startup. Now running a touch on the add-in dll (just to update the timestamp) results in an empty extension list. The output looks like:

After some further investigation it seems I have tracked down the problem. The issue occurs if there is a root add-in located in the Global Assembly Cache (GAC). During the first scan this add-in will be added with a domain e.g. "1". Then after adding another add-in, the framework tries to get the description for the GAC add-in from the "global" domain which is not available.
