Overall I'm pretty happy with 4.0 but it's not exactly stable yet. There are
a couple of bugs in particular that annoy me:
R# frequently stops parsing files. For instance, if I create a new class and
paste a piece of code into it, R# does not parse the new code to identify
missing references etc.. I have to close the file and reopen it. Very often
R# stops parsing all files and I have to close VS.
Go To Declaration will take me to the correct file, but normally takes 2
attempts to take me to the exact location.
