VB.NET business objects and COM+
In Beta 1 the COM+ interop functionality is not complete and is not
implemented as it will be in the final release. In fact, it is not entirely
clear how it will work in the final release, but yes, it will be possible to
create a transactional .NET assembly (thus running in COM+) that can be
called from COM-based applications.
In general, it appears that the .NET assembly will need to implement a
formal interface (using the Interface keyword) and will need to make use of
the transactional attribute (so it goes into COM+). Once the assembly is in
COM+ we should be able to call it from a COM-based client via that formal
interface.
The problem with 'simple' Beta 1 examples is that there aren't any. In Beta
1 the process is a multi-step thing that is generally just awkward...
Fortunately this will change.
