Launchsettings.json not created using dotnet new

Question

I created a new ASP.NET Core Web API project using dotnet cmd, but it didn't create the default launchSettings.json file.

I tried adding the file manually but it still doesn't pick environment variables and command like dotnet watch run also don't work, is there some way to do it automatically using command line?

I used this comand: dotnet new webapi -o projectname -n projectname

my dotnet core version is 2.1

here's the screenshot of my created project structure:

Can someone please help me with this?
