Visual Studio 2019 Application Arguments for Dotnetcore function

I have build a donetcore function inside VS 2019 which failes without any hint

It mentions during start For detailed output, run func with --verbose flag.

But every application argument is causing a Error: unknown argument --verbose

How could I use arguments for better debugging ?

It is the proper place to pass command line arguments.

You just have to add start before --verbose, like so:

start --verbose
