Problem
You're developing SharePoint workflows in Visual Studio 2005 or Visual Studio 2008 and then all of a sudden you get these errors when you attempt to compile your solution. I've noticed that this happens most often when you rename on of your forms and/or you rename the xsd myschema.xsd /c file you've created.
