Patrick,

>I'd like to understand: With GetEntityList I retrieved the data (speaking of the Windows forms Jump start "Customer Orders" form). Now I expected to see the grid populated by the entity list as datasource. But the datasource still is a mmDataSet. I seem not fully to understand the concept. Can you help me?

That's right...for now, in MM .NET 2.4 there is an underlying DataSet--although it will be optional in future versions of MM .NET.
