We are about to release very soon a LIB, which you can test and share feedback. There will be more information about the lib and official releases in this sticky note: ASP.NET Core 1.0 RTM is Out
The official release of UI for ASP.NET MVC with full support for ASP.NET Core 1.0 RTM is planned for the middle of July.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
