I have Resharper 4 and some sort of Syncfusion Add-in.
It seems the only way to "reconnect" everything is to create a new project (e.g. a simple Windows application) but it doesn't always stay fixed.
However, the last time I restarted VS I recv'd this error:
"Package 'Visual Studio Explorers and Designers package failed to load properly... Please contact package vendor for assistance..."
It would seem this is a Microsoft package? Now I'm really baffled!!!
Finally, is it possible to remove Add-ins using the registry, or is that information scattered across the hive and/or filesystem?
