There I was happily debugging my code, when I did a restart, and even though VS said it was running my application, nothing showed.
When I hit stop, VS emptied itself of everything - solution explorer, all opened files, and all of the other panes (output, properties, etc.).
I've tried rebooting. Doesn't help.
Tried creating an empty (default) winforms project. Checked it runs ok standalone. Try running it from VS, same thing.
Do I really have to reinstall the whole caboodle?
(If I do a pause, I get 'No symbols to display', and I'm not smart enough to know what to do with the Disassembly - though the Address says System.Threading.WaitHandle.WaitOne).
