Question

I have the below XSD that I generated from a profile that I serialize using XAML 2009. However when my I put the schema in Online Validator I get src-resolve: Cannot resolve the name ‘scg:List’ to a(n) ‘element declaration’ component. error.

Your XML namespace scg is actually referring to:

clr-namespace:System.Collections.Generic;assembly=mscorlib

I doubt whether your schema validator has access to the mscorlib assembly.
