TFS2010: Build Configuration Issues - visual-studio-2010

Question

I have customized the build configurations in my solution by deleting the Debug and Release configurations and creating "Dev" and "Test". Everything builds fine locally but I get the following error (and others like it) when building one of the new configurations in TFS.
C:\Program Files
(x86)\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets
(177): Unable to copy file
"bin\CommonServiceFactory.dll" to
"C:\MyApp\Binaries_PublishedWebsites\Epsi.Web\bin\CommonServiceFactory.dll".
Could not find a part of the path
'bin\CommonServiceFactory.dll'.
I'm getting this error for both external and project dependencies. From the posts I've read it seems to be related to the build configuration changes I've made. If I set the TFS build to use the "Debug" configuration I do get a warning but it builds successfully.
C:\MyApp\Sources\MyApp.sln.metaproj:
The specified solution configuration
"Debug|Any CPU" is invalid. Please
specify a valid solution configuration
using the Configuration and Platform
properties (e.g. MSBuild.exe
Solution.sln /p:Configuration=Debug
/p:Platform="Any CPU") or leave those
properties blank to use the default
solution configuration.
Any help would be most appreciated.

Answer 1

The error message indicates that you do not have the dll in the bin\ directory. If you can get on the build machine, can you check to see where the assemblies of your projects were built to? Make sure the path to the assemblies is the one used by the copying/publishing task to copy the assemblies to the Binaries_PublishedWebistes folder.
If this doesn't help, can you post the msbuild command-line from the TFS build details log up?
