I'm having no end of problems with Xamarin Studio 4.2.2. Intellisense isn't working, and neither are some context menus. For example, right clicking on a method name no longer offers up a "Go to definition" option (or something like that). I don't have any refactoring options either ("Rename..." etc).
How can I restore this? Any idea what's caused this?
Working without this for a day has been a real chore (I had to get something wrapped up today).
