I took your XML and added a closing tag (</Project>) to make it 
well-formed, then run the following piece of code using your XPath 
expressions

       XmlDocument xmlDocument = new XmlDocument();
       xmlDocument.Load(@"file.xml");
       XmlNamespaceManager namespaceManager = new 
XmlNamespaceManager(xmlDocument.NameTable);
       namespaceManager.AddNamespace("def", 
"http://schemas.microsoft.com/developer/msbuild/2003");
       foreach (string expression in new string[] { 
"/def:Project/def:PropertyGroup[1]/def:OutputType/text()", 
"def:Project/def:PropertyGroup[1]/def:AssemblyName/text()"}) {
         Console.WriteLine("SelectSingleNode with expression \"{0}\" 
finds: {1}.", expression, xmlDocument.SelectSingleNode(expression, 
namespaceManager));
       }

and both expressions find a text node, output is

SelectSingleNode with expression 
"/def:Project/def:PropertyGroup[1]/def:OutputType/text()" finds: 
System.Xml.XmlText.
SelectSingleNode with expression 
"def:Project/def:PropertyGroup[1]/def:AssemblyName/text()" finds: 
System.Xml.XmlText.

Make sure you use the same namespace URI in both the XML document and 
the .NET code with its namespace manager.
