title: MSBuild does not compile resource files
body: <p>I have a solution with multiple projects (it's a Silverlight application). Many of projects in solution contains resources (resx) files. When I build solution with Visual Studio everything is compiled and embedded ok (for example en-US folder in XAP file), but when I build the same solution with MSBuild the resource files are not compiled/embedded into XAP files.
  How do you tell MSBuild to process resource files like Visual Studio do?</p>
