Hello,

What is the diference between calling the DTS library from VS .NET by
addinga a reference to the COM object and creating a RCW yourself and then
reffering to that? DOes .NET build a RCW for you behind the scenes when you
select the COM object in the references? What are tbe benefits and
drawbacks of both approaches?

Thx

Visual Studio builds one on the fly when you add the reference. They should
be identical in terms of functionality, but:
1) Visual Studio will create on for every project, if you have lots of
projects referencing the same COM object you have a lot of disk bloat going
on
2) You might want to strongly sign your COM wrapper and place it in the GAC,
Visual Studio will not do this for you, you have to do this manually
3) I personally like to create them manually since you know exactly which
flags and options are used and it is no-hidden magic from the IDE, which I
hate, because it has bitten me more then once before
