Project location is not fully trusted - solution

[Chris Gilbert]

I spent nearly a day trying to fix this so this is a helper post as
I'm sure this is a bug.

I created a new solution containing two projects on a network share
*before* I had set up full trust on the share. I did get a message
explaining I would get problems which I ingored. When I went into the
solution from then on I would get the above error and then various
spurious security errors when I ran it.

I checked the help file but that has the .net security configuration
syntax wrong so that didn't work. Then I checked the groups. Every
one says that all you need to do is fully trust the share. This did
not work for me, I still got the error.

Thinking I had done something strange to my machine I tried to access
the solution on someone elses. This time I set up the trusts before I
opened the solution. He got in fine... Arrghhh.

This is the good bit though: when I went back to my desk in confusion
and tried once more to get in it let me! There is obviously some sort
of bug in VS going on here but I hope this helps someone out.

Cheers.
