My build script has the following:
<Import Project="$(MSBuildExtensionsPath)\ExtensionPack\MSBuild.ExtensionPack.tasks"/>
<MSBuild.ExtensionPack.Tfs.DevEnv TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Solution="$(SolutionRoot)\%(InstallerFile.Identity)" SolutionConfiguration="$(Config)" SolutionPlatform="" Target="Build" Version="10" />
In the build log:
DevEnvDir = *Undefined*
Does this have anything to do with this error?
Thank you

After taking a break from this for a while, and taking a look at this again this morning... i realized that there was a new tfs package for tfs2010 (don't know how I didn't see this before). I've modified my build script to now use the tfs2010 version, but now I get the following error:

I've looked in the private assemblies for visual studio 2008 (note: the compatability pack was installed so that visual studio 2008 would work with tfs 2010), and I can't seem to find the dll. There's a *.VersionControl.Client.dll, but no *.versioncontrol.dll. Does anyone have any insight into this issue? Any help would be greatly appreciated.
