Few weeks before this post someone sent post with his .targets file. It
should be in the archive. (I don't know if attachment is also archived)

Current xbuild won't build project from .csproj file because some
features use by Microsoft.Common.targets are not implemented and because
of that this .targets file is not made for Mono but Microsoft .NET

At this moment it should be possible to use mcs by
Microsoft.Build.Tasks.Csc from xbuild. You would need to load it
(UsingTask) and create your own version of Compile target. You need to
be sure that VS does not use
HostObject(Microsoft.Build.Tasks.Hosting.ICscHostObject) compiler which
is implemented in VS2005 but not in MSBuild or xbuild.

I'm working on rewrite in xbuild. When I'll get some free time I'll
write more tests and fix bugs. (like AL task that isn't reporting
errors/warnings properly)
