• .NET Development Typed-dataset/Table Adapters - multiple database vendors - how?

  Hello here is my objective.  I want to take advantage of the visual tools in VS 2005, specifically the dataset designer.

Normally, we would create some sort of provider model (similar to DotNetNuke). With VS2005, the code generation could save us a lot of time. However, here's what I'm fi ...Show All
