Getting an error in .net 4.0

I've been getting this error for expression tree serialization in .net 4.0: "System.Xml.XmlException : The '`' character, hexadecimal value 0x60, cannot be included in a name.
at System.Xml.XmlConvert.VerifyNCName(String name, ExceptionType exceptionType)
at System.Xml.Linq.XName..ctor(XNamespace ns, String localName)"

This doesn't occur when the ExpressionTree is used against previous versions of .net, it must be because Xml validation is tighter in 4.0.

I'm getting the same error for simple expressions like this:
Expression<Func<string, bool>> x = f => true;
is there a possibility to get a .net 4 specific build?
