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!

Comment: If you have suggestions, please let me know in the comments. Any product feedback will be forwarded to the proper product team.

Question: Should I add Entity Framework in this update as well? Let me know in the comments.

Hi everyone!

So the .NET Core 3.0 has released, things have settled down a bit and we’re ready to start the fifth month of this .NET-related documentation update. This update covers everything that happened since October 1st through November 5th.

My name is Maxime Rouiller and I’m a Cloud Advocate with Microsoft. For this month, I’m covering three major products:

• .NET, which had ~575 commits, and 4,599 changed files on their docs repository and ~124 PRs on their API docs repository
• ASP.NET, which had ~288 commits, and 1,317 changed files on their docs repository
• NuGet, which had ~32 commits, and 26 changed files on their docs repository

As with last month, here’s the legend that I will use to mark certain article with certain level of important. Much more useful than writing a blurb beside each one. I know, we’re not Twitter. Dare I say I’m using emojis for good? \

Legend

• 📢: Major/Main article that everyone will want to read
• 💥: Important/Must read.
• ✨: Brand new page

Note: It’s not because a page doesn’t have an icon that it is not important. Everything here is either brand new or significantly modified.
