csproj from VS2008 fail to compile with mono xbuild

I use Mono 2.6.4 compiled from source on CentOS to compile a VS2008 project in C#. Some csproj compile, but this one doesn't, here is the output of xbuild /t:detailed :

/opt/mono-2.6.4/lib/mono/2.0/Microsoft.CSharp.targets: error : Error executing开发者_如何转开发 task Csc: Input string was not in the correct format

Anyone has an idea ? Thanks ?

This might already be fixed in svn. I changed that code to use regex some time back. Could you try this with a mono daily build [1]? Or just file a bug with the project file and i'll check it.

It's probably a bug in xbuild. File a bug with a test case to get it fixed:
