v6.0A no longer compiles my VC NEt projects

[Kim]

I'm having the same problem. When building a C# (VS2005) project using default (=MSBuild) executable, the following error message appears:

Building project step 'Build LM'...
Pre-processing...
Input string was not in a correct format.
Step 'Build LM' failed
Build ended.

If I change the “Override the default location of the DEVENV/MSBUILD/VCBUILD executable” to devenv, then I am able to continue (but then I have other problems with solutions including setup projects)

I’m using VBP v6.0a. Attached is a logfile from regmon performing the failing build step.
