Using Generics in CRM 4

Generics can be used to simplify the CRM Web Service method calls.

account acc = CrmSystem.Retrieve(myAccountId);

Here is one of the overloads for the Retrive Method that uses Generics, it calls an other overload that does the actual call to CRM Web Service using the EntityName string that we get thru typeof(T).Name

public T Retrieve(Guid id, params string[] columnSet) where T : BusinessEntity { 
     return (T)Retrieve(typeof(T).Name, id, new ColumnSet(columnSet));
}
