Property Value

Type	Description
String	A String value that specifies the type name of persistent objects that provide data for joining. The value is case-sensitive.

Remarks

If a criteria contains types from different namespaces, the JoinOperand.JoinTypeName property should contain the full type name with its namespace, for example, as follows:

"[<Application.SomeNamespace.Customers>][^.GroupID = GroupID].Count() > 1 
and  [<Application.OtherNamespace.Orders>][^.EmployeeID = EmployeeID].Count() > 50"
