This error can occur when Xamarin Studio fails to load key add-ins. MonoDevelop appears because it's the foundation underneath Xamarin Studio.

Important note Unless you've manually edited the add-ins or something similar; this is most likely caused by a bug. In this case, please contact support, or file a bug.


Usually this issue can be resolved by the following steps:

  1. Close Xamarin Studio. (aka MonoDevelop per the symptoms)
  2. Zip up a copy of the Xamarin Studio Cache from your machine to submit with a bug report:
    • Mac: ~/Library/Caches/XamarinStudio-5.0
    • PC: %LOCALAPPDATA%\XamarinStudio-5.0\Cache
  3. Delete the cache from the location listed in step 2.
  4. Restart Xamarin Studio. It should automatically restore the cache, generally correcting the error in the process.

Xamarin Workbook

If it's not already installed, install the Xamarin Workbooks app first. The workbook file should download automatically, but if it doesn't, just click to start the workbook download manually.
