You probably need to add a reference to the namespace http://schemas.microsoft.com/developer/msbuild/2003.

I had a similar problem, I wrote about it here. Do something like this:

xdDoc.Load("blah/blah.csproj");

XmlNamespaceManager xnManager =
 new XmlNamespaceManager(xdDoc.NameTable);
xnManager.AddNamespace("tu",
 "http://schemas.microsoft.com/developer/msbuild/2003");

XmlNode xnRoot = xdDoc.DocumentElement;
XmlNodeList xnlPages = xnRoot.SelectNodes("//tu:ItemGroup", xnManager);
