MS please provide a solution to this.

Windows 2000 / Visual Studio 7.0.9466 / .Net Framework v1.1.4322

I have a solution ( based on the MS Commerce Server International
Retail Site Reference ) which contains 12 projects. (7 VB and 4 C#)

If I open the IDE, click [Build / Rebuild Solution], my compile is
successfull. If I click [Build / Rebuild Solution] again, the compile
dies on one of the C# projects.

Performing main compilation...
error CS0016: Could not write to output file
'd:\onlinestore\Components\obj\DebugAll\Microsoft.CommerceServer.Retail2002.Components.dll'
-- 'The process cannot
access the file because it is being used by another process. '

and no subsequent compile attempts will succeed. My only solution thus
far has been to exit the IDE, delete the "obj" directory of the
offending project, ( Depending on the build order it is not always the
same but it is always a C# project / never VB. ) rebuild the solution
from the commandline "devenv /build debugall
d:\onlinestore\Retail2002.sln"

I have followed the direction in QB313512
I do not have projects that are compiled to the same output folder. I
have only project references, and none of the references to these
projects are marked with "Copy Local" as false. (I should note that
this wasn't always a problem. I suspect that I reached the 64kb limit
mentioned in the KB article and began experiencing these issues. )

I have resorted to managing the build process manually using the
Configuration Manager to enable and disable the projects I'm working
on, but if I have to make a change to any of the C# projects I am
forced to reopen the IDE.

If anyone has any suggestions. I am open to anything. If it means
reworking my solution, that's fine. I would prefer to continue my
builds within the IDE but this is increasingly more painfull.

Frustrated
