We try to keep up with the latest versions of .NET Core on our azure services. At the time of reading, azure is not supporting .NET Core 3.0 as their Azure app service deployment.
Azure App Service deployment of .NET Core 3.0 is currently ongoing. See our tracking site to track when .NET Core 3.0 is available in your region.
So I went and searched for a solution:
Solution 1: Publish as a self contained app
What is a self contained app?
This is simply an app that ships its runtime with it. So, if I have a .NET Core 3.0 app, guess what?! .Net Core 3.0 runtime will ship with it! This is exactly what we need if we want to host it on azure!
Since the Microsoft documentation about self contained apps is pretty neat, I’ll save myself some time explaning it and guide you to the official Microsoft documentation:
Solution 2: Extension .Net Core 3.0 on Azure App Service
Voila! Hopefully this brings you a step closer to a .NET Core 3.0 app on azure!
