Sounds like a good plan :) For those remaining WinForms projects I've
got a VirtualBox VM of XP for development and testing, but everything
else I do is using MonoDevelop in openSUSE

If you're comfortable with the idea, then I'd strongly recommend getting
involved in helping to improve MonoDevelop. I've not got to the stage of
contributing code, but I've been running the bleeding edge version for
the past few months, contributing loads of bugs (as Mike Krueger will
attest to ;) ) and generally providing thoughts, suggestions and feedback.

I'm not sure if MonoDevelop supports as much as Eclipse and R# probably
do (different colours and styles for boxed types, static access, etc),
but there is more to the colour themes than the defaults seem to
indicate. Have a look at
for quite a good write-up and then submit a feature request if it needs
to do more (http://monodevelop.com/Developers#Reporting_Bugs)

I got confused by "Toggle Completion Suggestion Mode" as well -
apparently that's just to determine whether it auto-selects the results
or not (i.e. whether it autocompletes on punctuation or whether you've
got to actively pick the suggestion).
Ctrl+Alt+Space and auto-adding of "using" references is a feature I use
a lot in the dev builds, so either it made it into v2.4 and you're still
using v2.2 or else it was added after 2.4 and it'll be in the next
release (or the dev release if you want to build from scratch)

F3 is the "go to definition" (I think - or maybe I just mapped that
because it is what Eclipse uses).
As for the assembly browser, it does exist, but I always get to it via
the References (double-click on a reference). I've just checked what
you're mentioning and it appears that "Go To Definition" on a
base.SomeMethod() where base is a class from an assembly just goes to
the highest level in your code. Mike just fixed another issue with "Go
To Definition" that I reported the other day, so maybe that'll get fixed
with a bug report as well :)

Sorry, never used it. I'll leave that to others.

I think they both need a feature request in the bug tracker. I know
Eclipse has a little button to enable and disable occurrence
highlighting, but I think it tracks the cursor as well. I've not seen
anything like that in MD, though, and it does seem to always be on.

Ah, that'd be one reason to wait a little on the dev builds, actually.
Someone has broken the "Extract Method" refactoring at the moment! It
works (the code is extracted) but it forgets the method name you gave it
and so it just gets called "()" rather than "MyExtractedMethod()". I've
not noticed any bugs with extracting and inlining variables in the dev
