I also needed to add CompatibleFrameworks. I also tried do add the CompatibleFrameworks like this (which does not work)

dm.CompatibleFrameworks.Add(...);

My solution was to set:

dm.TargetFrameworkMoniker = ".NETFramework,Version=v4.0";                 

After this the Manifest generation was correct.

Be careful If you set the TargetFrameworkMoniker before WriteManifest you have the twice and your application file is corrupt. Here is my solution for this:

DeployManifest dm = ManifestReader.ReadManifest("DeployManifest", applicationFileName, false) as DeployManifest;
dm.ResolveFiles();
//doing stuff..
dm.UpdateFileInfo();
ManifestWriter.WriteManifest(dm, applicationFileName);
dm.TargetFrameworkMoniker = ".NETFramework,Version=v4.0";
ManifestWriter.WriteManifest(dm, applicationFileName);
