This is a simple fix for bug https://bugzilla.xamarin.com/show_bug.cgi?id=5937 .
BreakpointStore: Fix typo in parameter name
[Debugger] Disable "Exceptions..." command when no solution open
Disable "Exceptions..." command when no solution open, otherwise the user
gets an exception if executing it.
Fixes bug #5937.
This isn't the correct fix, the dialog does have support for handling the case where there isn't a solution open, if we land this fix then that code will become redundant. I assigned the bug to Mike so he can fix the type system service...
No need for the type system service to be fixed - the load assembly context method is strange a bit - it takes either file name or full name. But that thing was introduced in the old project dom. Using file names works.
