While working on a project that was having issues with the Oracle's data provider for .NET (ODP.NET), I found myself looking for alternatives, which led me to a hunt for supported connection string attributes. I must say that this search was harder than I originally thought it would be. Perhaps I wasn't looking for the right thing, but I figured I'd document what I found here for future use and hopefully to help someone else out. If anyone has any information on what I've gathered here, please don't hesitate to let me know. My hopes are to gather as much valid information as possible; or, if there's already a good, up-to-date resource available with this information, I'd have no problem linking to that.
Most recent update: Added connection string info for Oracle provider and details about Active Directory authentication.
