How to Create Unique Constraint with Multiple Columns using ServiceStack.OrmLite?

ormlite-servicestack, servicestack

Solution

Service Stack appears to have a CompositeIndex attribute which takes multiple field names. Here's a look at the constructors...

CompositeIndexAttribute(params string[] fieldNames);
CompositeIndexAttribute(bool unique, params string[] fieldNames);

Problem

How does one create a unique constraint with ServiceStack.OrmLite (using attributes, hopefully)? The documentation shows how to create a unique constraint only on a single column: ServiceStack.OrmLite Docs If it helps, I am using `ServiceStack.OrmLite.SqlServer`.
