TLDR; This is a status update on the .NET documentation. If you want me to do more of those (once a month), please let me know in the comments!

Hi everyone!

So the .NET Core 3.1 has finally released in the last few days, so expect lots of things related to this.

This update covers everything that happened since November 1st through December 4th. Although not everything has yet been updated for 3.1, expect a lot more coming next month!

If you still don’t know me, my name is Maxime Rouiller and I’m a Cloud Advocate with Microsoft. For this month, I’m covering three major products:

• .NET
• ASP.NET

You’ll find a nice legend below that explains and highlights articles that I think deserves special attention.
