asp.net core targeting .net framework

Question

I'm adding a new asp.net core project straight from Visual Studio (16.3.2). I'm Targeting the .net framework and ASP.Net Core 2.2 and making no edits.

I'm then publishing to Azure app service and see what id expect for the standard new proj.

Next, I need to reference another library which is built-in .net 4.8 so change the target framework from net461 to net48 and republish (prior to adding a reference to the other library.

HTTP Error 502.5 - ANCM Out-Of-Process Startup Failure

From some of the reading I can find I see that The in-process hosting model isn't supported for ASP.NET Core apps that target the .NET Framework. but it was previously when targeting the earlier version of net461?

In the scm console, i can see this event logged.

Questions

Can someone give me a steer in the right direction please?
Where is the best place to find out about this sort of infomration, does anyone have any helpful links?
General rant, why is this hard from a simple new project template

This isn't related to in-process - you don't have that enabled in the csproj and the error message shows "Out-Of-Process Startup Failure". As for what it is, that's really difficult to tell at this stage. Have you checked through the logs? It's possible that .NET Framework 4.8 still isn't support in Azure App Services, but I dunno if that's actually the case. — Kirk Larkin

Why are you targeting .NET Framework in .NET Core project? Target .NET Core. — petesramek

Failed to bind to port '8399' seems to be the critical error here? — DavidG

It's because .net48 is not installed on Azure App Services yet. When I downgraded to .net471 is worked. Now the waiting game.
