dotnet faqs : Visual Studio .NET Bug

We are experiencing a debilitating VS.NET bug, in both 2002 and 2003.
We have solution with about 20 projects. 90% of the time, when we
rebuild, we get one or more errors saying "Cannot copy assembly 'xxx'
to file 'yyy'. The process cannot access the file because it is being
used by another process."

Sometimes, waiting 30 seconds makes this go away. Sometimes, we have
to exit and restart VS.NET. Sometimes, we have to reboot Win2k.

I have seen this bug posted MANY times in Google, and on GotDotNet.
No uSoft engineer has responded.

Check your references. Have you set Copy Local to True?

If your building a large solution with redundant references there's a chance
that the file could still be in use when it tries to copy it in again. This
results in the error.

Microsoft is recommending that you build to individual output directories.

You could then set up a script to copy them to a common folder once they are
built.

Also note that they recommend using project references.

I experience this problem intermittently. I have local copy set to true on
the references. Should this be the case?

I have all my projects set to build their executables to a single directory
as they form part of the same application.

Thanks for the help,

Trev.

I have this problem frequently on my project as well. I believe part of the
problem is that I'm creating controls and using them on forms (or other
controls) in the same project. I believe VisualStudio isn't unloading the
used controls from the designer once they're loaded, meaning that I have to
shut it down frequently. I sure hope they fix it at some point - I kinda
miss "real" dll's that unloaded properly.

99% of the time it works ok. Closing and reopening the IDE isn't that much
of a pain (yet!)

Yep. I'm using project references.

Thanks for the help.
