Last month JetBrains -- of ReSharper fame -- unveiled its plans for a C# integrated development environment that would effectively come with ReSharper and IntelliJ built-in. If you want to give it a try, JetBrains is now taking down details for its Early Access program.
To get involved, just hit up the Project Rider page on JetBrains site. Along with a breakdown of features, you'll find a sign-up form at the bottom. It's nothing complex -- name, email and a few survey questions.
After the subscription step, you'll be informed that "as soon as [Project Rider] builds are ready, you will receive further e-mails with download links".
So no definitive dates, sadly, but I'm sure we won't be waiting too long.
