This does not actually work. I have tried it in VS2008, giving a valid XSD file and an XML file that does not match the schema in any respect and did not get any errors.

When I made the XML file invalid, the XMLDocument.Load call did raise an exception as expected. Invalidating the XSD also caused an exception in Schemas.Add; however, the functionality claimed in the article title is non-existent.

This code won't actually compile. That may be my fault, but I am pretty sure that there are some sytaxish errors here:
if(!String.IsNullOrEmpty(ErrorMessage.ToString()))
{
MessageBox.Show(ErrorMessage.ToString());
}
where does ErrorMessage get defined?
