BizTalk Schema Build Error

During my current project I ran into a annoying and kind of misleading error message when building Biztalk schema’s with BTS 2010 in combination with TFS 2010. The errormessage is similar to “MySchema.xsd.cs’ could not be opened (‘Unspecified error ‘)”

The reason and a possible solution is explained in this blogpost But unfortunately that solution didn’t work for me:(

After that I also tried the registry hack mentioned by Charles Young:

And also the solutions proposed on this blogpost

But all with no luck!


After trying a rebuild I suspected it had something to do with rights, so I started to investigate the folder structure. Then I had my lightbulb moment.

TFS put the read-only flag on my workspace folder. After removing the read-only flag from the folder I was able to build again. So in the end it’s just another solution to an already known problem in blogosphere 🙂
