EF7 is now EF Core 1.0, Package and namespaces change too

The big news last week was that the ASP.NET 5 & EF7 stacks were renamed in an attempt to alleviate the confusion around the naming of everything under the ASP.NET 5 umbrella.

ASP.NET 5 is now ASP.NET Core 1.0

EF7 is now EF Core 1.0

The naming has been a topic of debate since each of these were introduced by Microsoft and throughout their development. The teams finally accepted that the myriad questions and complicated answers about the naming in the ASP.NET 5 stack was enough of a red flag to change the names. While it is a huge relief to many, the timing is problem for people who have invested in asp.net 5 already because the name is not just a brand but it will affect packages as well. As per the announcement on github

The Microsoft.AspNet.* packages and namespaces are changing to Microsoft.AspNetCore.*.
The EntityFramework.* packages and namespaces are changing to Microsoft.EntityFrameworkCore.*.
The version numbers of all of the above are being reset to 1.0.0-*.

Changing the namespaces this late in the game is going to be painful for devs/companies who have already been building apps and tooling on ASP.NET 5 &/or EF7. We are already on RC1 which was released in November with a go live license. .

Other than this, both ASP.NET Core & EF Core will move forward as planned. RC2 is supposed to be out sometime in February and they remain committed to the initial RTM at the end of March.

Here are the new namespace names for EF Core for RC2, as per https://github.com/aspnet/EntityFramework/tree/dev/src
