I developed ASP.NET website for five years. Recently I upgraded to VS2022 recent release, then R-Click on the project name in Solution Explorer I ran "Analyze and Code Cleanup". Now, I get a build error "CS5001: Program does not contain a static 'Main' method suitable for an entry point" Also, I do not see an option to set the project StartPage? How can fix this?

    Reverting the last change (large size change) will be my last resort. Switching to Class Library eliminated the build error but introduced a debug error: "The 'RunCommand' property is not defined." The program does not start. What should I try next? Thanks!!!
