Team Foundation Server 2010 / MSBuild: Error parsing the nested project section in solution file

Question

I'm trying to set up a nightly build for one of my company's products. When I execute the build, it fails after 45 or so seconds, giving the error "Error parsing the nested project section in solution file.

This is the log from the build:

00:18 Get Workspace

00:01 Create Label Label [label] (version W60_2_VMCORPTFS01;CL\me) was successfully created.

00:00 Built $/OMS/Branches/Product_2.0/Product/Product.sln for default targets. e:\localstore\ThisSpecificBuild\Product\Product.sln (1586): Error parsing the nested project section in solution file.

And this is the log from MSBuild:

Build started 7/6/2011 11:53:34 AM. e:\localstore\ThisSpecificBuild\Product\Product.sln(1586): Solution file error MSB5009: Error parsing the nested project section in solution file.

Build FAILED.

The solution builds correctly from within Visual Studio.

Answer 1

Try to remove and then re-add some file, to cause sln file to be regenerated. This way I got build succeeded. My sln file was in an incorrect format for some reason.
