UccOperationContext in background thread

Question

Following simple code complain about an access violation when executed in a background thread. It works fine if executed in an UI thread. Any one know how to fix this?

UccOperationContext context = new UccOperationContextClass();
context.Initialize(1, null);
context.Context.AddProperty(1, session.GetHashCode());

Or 

UccOperationContext oc = new UccOperationContext();
UccContext c = new UccContextClass();
c.AddNamedProperty(key, value);
oc.Initialize(1, c);

This does not work in just background thread because this is COM API and need message loop. Created thread with message loop to avoid issue.
