According to this link MySQL AB has joined the Microsoft Visual Studio Industry Partner (VSIP) program and is now developing a plug-in for Visual Studio 2005. It will allow Windows developers to build MySQL data-driven applications from within Visual Studio. From MySQL ABs press release:

With this plug-in, developers will be able to create, modify and manage MySQL database objects with an easy-to-use interface from within the Visual Studio IDE.

That’s nice I think. But according to this comment they should have used their time to update their data provider to support more of the ADO.NET 2.0 features and the MSDTC (Microsoft Distrubuted Transaction Coordinator).
