"The specified version of Microsoft.NetCore.App or Microsoft.AspNetCore.App was not found."

Everything I've read led me to believe that .NET 5 is ready to be used for an app service. So I made the necessary changes and merged my code. The build (pipeline) went find. The release made it to the App Service. But for some reason the machine with the App service does not have .NET 5 installed. My question is, am I wrong in assuming that Azure is raeady to host .NET 5 applications. If it is possible, then how do I do this?

    Also having this problem, but chaging to .Net 5.0 did not solve the problem.

    I cannot change to 64bit because the drop down is greyed out.

    When I run set pro in the console it appears to be on 64bit, even though it says 32bit in the greyed out dropdown.

    This is very frustrating.

    After changing Platform from 32 to 64 bit, everything worked fine.

    Azure App Services supports .NET 5: Read More: .NET 5 now available in App Service

    Did you change the target framework of your app service to be .NET 5?

    If you are creating a new app service, you can see .NET 5 under Runtime stacks.
