Our company needs to present our customers with a dialog to configure ADO.NET connection strings and to take advantage of the extensibility 3rd party providers are developing for.

Although ADO.NET is advertised as an open technology, the connection string dialogs and DDEX do not appear to be particularly open.

We have downloaded the ConnectionDialog source release by Microsoft in early 2010, but find that it only supports the basic Microsoft providers. It does not load, or indicate how one might load 3rd party provider implementations of the Data Connection UI.

How does one load 3rd Party implementations of connection string dialogs via C# code when Visual Studio is not installed on the user machine?
