ANCM In-Process Start Failure, ASP.NET Core 3.1 apps after upgrading to VS 2022 v17.8

Question

Tried Repair, Rollback, Repair, Re-install and fresh install on HYper-V nothing works.

--------Update---------

Installing VS 2019 : new project generation for 3.1 generates empty solution, and old project from 2022 are not loading.

For now - navigating to project folder in command prompt and executing "dotnet run", is keeping things going.

Publishing is working ok.

Issue is in triage for now: https://developercommunity.visualstudio.com/t/After-updating-to-VS-2022-v178-net-cor/10517164

Install .NET Framework 7 SDK : https://dotnet.microsoft.com/en-us/download/dotnet/7.0

1. In VS top menu > Tools > Options

2. Navigate to Projects and Solutions > ASP.NET Core

3. Set Auto build and refresh option to None

This worked for me, hope this helps you too.
