I love posting announcements to the blog to let people know about the latest and greatest information about Entity Framework-enabled ADO.NET providers. Blogs are perfect for announcements like that, but they're not as handy for providing an overview about the available Entity Framework-enabled providers.
To help customers quickly and easily see what Entity Framework-enabled providers are available, released providers are listed on the main Entity Framework page here. We also have a separate page that lists all publicly available providers, including pre-released providers here.
We'll continue to post announcements about provider availability to the team blog. The corresponding entries will appear on the provider list pages within a couple days, since those changes require more time to format and review.
