XML Validation with XSD in Visual Studio IDE

Question

I know I have done this before, but it isn\'t working today, nor can I find anywhere that explains how to do it. It could be my lack of sleep, but I suspect gremlins.

Answer 1

You don't need to manually associate the files in Visual Studio - it will automatically match an XML file to a XSD file if you have them both open, and you have your namespace defined correctly.

To define the namespace:

In the XML file's root element:

    ...

In the XSD file's schema element:

    ...

A note on using Types in your schema when you have a targetNamespace

Because you are specifying a targetNamespace in your schema, any references to types defined in the schema will need to be prefixed with a namespace (which is why we added the xmlns:this attribute in the above element).
