Getting a compile error in c# about not referencing System.XML, yes System.XML is being reference

Question

I am trying to add a new feature to an old program I wrote. However, when trying to get the program to build in VS express it spits back an error message to me.

Answer 1

Using a namespace does not mean you referenced something. You need to add a reference to System.XML.

If you are using Visual Studio, right click on references, click Add Reference and then select System.XML.
