Upgrade to Visual Studio 2010 has broken code generation - getting DirectoryNotFoundException

Question

I'm trying to migrate my solution (an ASP.NET web app with about a dozen dependent assemblies) to VS 2010 and am hitting some new build errors.

Error   909 Running transformation: System.IO.DirectoryNotFoundException:
Could not find a part of the path 'c:\Program Files (x86)\Microsoft Visual Studio
10.0\Common7\IDE\SomeProject\Templates\MyTemplate.xml'.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

The problem is pretty clear - it's trying to load the XML for my generated code, but instead of looking in $(SolutionDir)\SomeProject\Templates\MyTemplate.xml, it's looking in .\SomeProject\Templates\MyTemplate.xml (where . is the Visual Studio executable working directory, I presume).

There seems to be entirely too much magic behind the scenes and I can't locate any kind of preferences or config settings that define this. Seems like most of the generator config is in the registry.

Has anybody encountered something similar before?

Update: I'm running Visual Studio 2010 Professional 10.0.30319 RTMRel. As part of the migration I also allowed it to update my projects from .NET 3.5 to .NET 4.

Hello,

I'd suggest looking into CodeSmith Generator, it has many advantages over T4 and you won't have to wait a very long time for a bug fix.
