Announcing Entity Framework Core 3.0 and Entity Framework 6.3 General Availability
We are extremely excited to announce the general availability of EF Core 3.0and EF 6.3 on nuget.org. The final versions of .NET Core 3.0 and ASP.NET Core 3.0 are also available now.

For example, to add the SQL Server provider to your project, you can use the following command using the tool: When upgrading applications that target older versions of ASP.NET Core to 3.0, you also have to add the EF Core packages as an explicit dependency. Also starting in 3.0, the command-line tool is no longer included in the .NET Co...
Announcing F# 4.7
We’re excited to announce general availability of F# 4.7 in conjunction with the .NET Core 3.0 release! In this post, I’ll show you how to get started, explain everything in F# 4.7 and give you a sneak peek at what we’re doing for the next version of F#.

Release Candidate builds of Entity Framework Core 3.0 and Entity Framework 6.3 are now available
We previously said that preview 9 would be your last chance to test EF Core 3.0 and EF 6.3 before general availability. But it turns out that we made enough improvements to our libraries and across the whole of .NET Core 3.0 to justify publishing a release candidate build. Hence the packages for EF Core 3.0 RC1 and EF 6.3 RC1 were uploaded to nuget.org today. Consider installing daily builds Although RC1 builds contain several improvements, we took several more critical bug fixes after the RC1 branch was created. Detailed instructions to install daily builds, including the necessary NuGet feeds, can be found i...

Announcing .NET Core 3.0 Release Candidate 1
Today, we're announcing .NET Core 3.0 Release Candidate 1. Just like with Preview 9, we've focused on polishing .NET Core 3.0 for a final release. We are now getting very, very close. We intend to release the final version on September 23 at .NET Conf. Download .NET Core 3.0 RC1 on Windows, macOS, and Linux, available now. Details: Why RC1? The .NET Core 3.0 Preview 9 post stated that Preview 9 would be the last release before the final GA one. We, or at least the tireless writer of these blog posts, were mistaken. And now for the explanation. For technical and historical reasons, the .NET toolset (...
Finalization implementation details
Years ago I wrote a document on making finalization scanning concurrent. At the time there was an internal team that was using finalization as a way to resurrect objects and putting them back in their cache. While we’ve always advised to folks that finalization was for releasing native resources I couldn’t fault this team for using it the way they did. And of course finalization scanning was taking quite some time because well, there were so many finalizable objects to scan so I wanted to make this part concurrent. As part of the on-going latency reduction effort we’ve finally put this on the agenda. Of course be...
