Currently, the implementation is only returning the long data type which is a bit limited. We need to make sure that the return type would be of type object to support all return types.

Calls:

connection.Max<Entity>(e => e.DateTime);
connection.Max<Entity>(e => e.Int32);
connection.Max<Entity>(e => e.Double);

Acceptance Criteria:

All affected Integration Tests and Unit Tests must be fixed and passing.
