Announcing .NET Core 3.0 Preview 8

Today, we are announcing .NET Core 3.0 Preview 8. Just like with Preview 7, we’ve focused on polishing .NET Core 3.0 for a final release and are not adding new features. If these final previews seem anti-climatic, that’s by design.

Download .NET Core 3.0 Preview 8 right now on Windows, macOS and Linux.

ASP.NET Core and EF Core are also releasing updates today.

Details:

The Microsoft .NET Site has been updated to .NET Core 3.0 Preview 8 (see the .NET Core runtime version in the footer text). It’s been running successfully on Preview 8 for over two weeks, on Azure WebApps (as a self-contained app). We will move the site to Preview 9 builds shortly.

If you missed it, check out the improvements we released in .NET Core 3.0 Preview 7, from last month.

Go Live

NET Core 3.0 Preview 8 is supported by Microsoft and can be used in production. We strongly recommend that you test your app running on Preview 8 before deploying Preview 8 into production. If you find an issue with .NET Core 3.0, please file a GitHub issue and/or contact Microsoft support.

If you are using .NET Core 3.0 Preview 7, you need to move to Preview 8 for “Go Live” support.

Closing

The .NET Core 3.0 release is coming close to completion, and the team is solely focused on stability and reliability now that we’re no longer building new features. Please tell us about any issues you find, ideally as quickly as possible. We want to get as many fixes in as possible before we ship the final 3.0 release.

If you install daily builds, please read an important PSA on .NET Core master branches.

    I may have found a bug. I am on version 3.0.100-preview8-013656. When I call System.IO.Ports.SerialPort.GetPortNames() on my Raspberry Pi 2, it does not find any ports. I would expect it to find the UART0 serial port. Is there a better place to post this?

      I believe https://github.com/dotnet/core/issues would be a better place to file bug reports…

    Congrats guys! I’ve been following along from the time that .net core was called asp vnext. The blazor model is absolutely amazing and it’s great to see the amount of enthusiasm around it in the community.

    How is it with Charting control in .net Core 3.0 Preview 8? We were using Charting in our asp.net framework web project to create a chart as png file, sending it automatically via e-mail to our customers. Is it possible to create chart in .Net Core 3.0, and save it automatically as a png file?

    I just found https://dotnet.microsoft.com/ is still showing preview 7 in its footer.
