I always used to deploy my Azure Web App during development. I suddenly updated my Visual Studio 2022 (preview) and after publishing the following error appears on the Web App:

HTTP Error 500.31 - ANCM Failed to Find Native Dependencies

How do I debug this further? I tried using the console in Azure Portal, but I could not find .NET 6 anywhere on the Azure Web App. Or actually how do I match the version on the web app with my own version?? I have no clue where the runtime is installed on the Web App as I've previously mentioned.

Based on the MS Doc .

This release is not "go-live" and not intended for use on production computers or for creating production code. For instructions on installing and updating Visual Studio 2022, see this documentation on updating Visual Studio 2022 to the most recent release.

For this error

HTTP Error 500.31 - ANCM Failed to Find Native Dependencies

You can try to Uninstall all the EF Core nuget packages and reinstalling them.

  • I've already tried settting the environment to development it seems to not throw any more exact errors... I tried listing packages or updating them with NuGet and it all failed... Even self-updating nuget.exe failed... I'm quite desperate at this point – Munchkin Sep 20 '21 at 10:48

The solution was to go to the project folder/bin/Debug or Release according to your deployment selection in Visual Studio and then editing the projectnamehere.runtimeconfig.json file to the correct version number.

You can figure out the correct runtime version number by going to wwwroot (should be the default path by default) via Console in Azure Portal and then executing dotnet projectname.dll.

Case closed.
