Description

Hi

My project works 100% in VS2008.

But now testing on VS2010, MSBuild reports the following:

C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(3159,9): error MSB3021: Unable to copy file "C:\DevProjects\IronScheme\IronScheme\IronScheme.Console\srfi\2\and-let%2a.sls" to "bin\Release\srfi\2\and-let*.sls". Illegal characters in path.
C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(3471,9): error MSB3541: Files has invalid value "bin\Release\srfi\2\and-let*.sls". Illegal characters in path.

As you can see, it 'decodes' the filename, and hence ends up with an invalid filename. The filename is encoded in the first place, so it does not have an invalid file character.

MSBuild should not be changing filenames (decoding or encoding).

Verified to be fixed in VS11 Beta.

Thanks

Can you please indicate the version of Visual Studio/.NET that will have this bug fix applied?

Or can you perhaps provide a hotfix?

I just installed the .NET 4.0 update, and the bug is still present in MSBuild.

When are you planning on incorporating it?

I cannot start using .NET 4/VS2010 till this is fixed.

I've investigated the bug and determined that the problem was in the AssignTargetPath task itself. This task was incorrectly causing the value placed in the TargetPath metadata to be escaped one time more than necessary. The bug is now fixed in our code base.

There is no workaround for this right now other than to rename the file to not use a %, which is what triggers MSBuild to perform escaping.

Exclude the content file from the project and then use a post-build event to copy the file to the target directory (e.g. bin\Debug).
