When you convert a Microsoft Visual Studio 2003 Tools for
Office InfoPath project
to a Visual Studio 2005 Tools for Office InfoPath project, all the non-default references are
removed. Additionally, when you try to build the project, you receive an error message
that resembles the following:
The type or namespace
name 'Xml' does not exist in the namespace 'System' (are you missing an
assembly reference?)

To work around this problem, re-add any reference that is
removed during the conversion process.
