I've been trying to write a Data Provider over some custom data that we have.
I've managed to write them in the past (connection, command, etc) and had
them work fine for code, but this time I'm trying to write one that will work
with SSIS/DTS 2008.

Unfortunateliy, there doesn't appear to be much documentation on the new
classes and interfaces introduced in .Net 2.0. For example, getting my
DbProviderFactory registered and working with DTS/SSIS 2008 has been exciting.

I'm now at the point where DTS can see the provider and start configuring
it, but I get a null pointer error along the way.

Since there are quite a few third-party providers out there, there must be
some documentation, but I haven't been able to find it. All of the examples
are for .Net 1.0/1.1, and I have that part working.

Any suggestions?
