.NET Core 1.0/1.1 End of Life


Entity Framework Core 3.0 Preview 6 and Entity Framework 6.3 Preview 6

In recent months, a lot of our efforts have been focused on a new LINQ implementation for EF Core 3.0. Although the work isn’t complete and a lot of the intended functionality hasn’t been enabled, before preview 6 we reached a point in which we couldn’t make much more progress without integrating the new implementation into the codebase in the main branch.

More interesting for me is Entity Framework 6.3 which is to support .NET Standard 2.1. Reminder, that won’t be supported on .NET Framework as it is not intended to support netstandard2.1. Only .NET Core 3 as of this time will support netstandard2.1


WF and WCF OSS projects

At the Build conference in May 2019, we mentioned that, after we add WinForms, WPF and Entity Framework 6 to .NET Core 3.0, we do not plan to add any more of the technologies from .NET Framework to .NET Core.

This means we will not be adding ASP.NET Web Forms, WCF, Windows Workflow, .NET Remoting and/or the various other smaller APIs to .NET Core. For new applications, there are better technologies that serve a similar purpose and provide more capabilities or better experiences. We think of .NET Core as the framework our customers will build brand new applications or port applications that they are still spending lots of engineering work on.


Hidden gems in .NET Core 3

You’ve likely heard about the headline features in .NET Core 3.0 including Blazor, gRPC, and Windows desktop app support, but what else is there? This is a big release so come and see David Fowler and Damian Edwards from the .NET Core team showcase their favorite new features you probably haven’t heard about in this demo-packed session.
