Answer 1

I had the same problem today and I am using Windows 7. Windows 7 uses powershell 2.0 so I upgraded it to 5.1, you can upgrade it from here - https://learn.microsoft.com/en-us/powershell/scripting/install/installing-windows-powershell?view=powershell-6

Upgrading this solved my problem. I found this solution from here - https://github.com/aspnet/AspNetCore.Docs/issues/14863
