From my end, I was facing this issue when trying to start IIS server on my local machine. I downloaded .NET Core 3.1 SDK and the problem is now solved.

Go to your App Service > Settings > Configuration and make sure that the Stack and the framework version match your app. In our case, after upgrading from .NET Core 3.1 to .NET 5 we had to switch the Stack from .NET Core to .NET and choose version 5.

After making the changes, you will also need to manually restart the App Service for the changes to take effect.

I have upgraded my Web API from version netcoreapp3.1 to version net6.0. When I launch it from Visual studio as localhost, it will launch successfully.

I have published the app to the azure app service to which it was previously published. Publish is successful. When I launch the URL I get the below error

" HTTP Error 500.31 - ANCM Failed to Find Native Dependencies Common solutions to this issue: The specified version of Microsoft.NetCore.App or Microsoft.AspNetCore.App was not found.

I checked dotnet --info command, .net 6 framework is installed.

Anyone has faced a similar issue? Could you please help me with this
