az webapp create can't create a dotnet core app

Describe the bug It is not possible in azure cli to create a webapp with .net core runtime settings for a non-linux host. It can be set in the arm template with

          "metadata": [
            {
              "name": "CURRENT_STACK",
              "value": "dotnetcore"
            }
          ]

To Reproduce Try running (or similar)

az webapp create -g test-rg -n test-app --runtime "dotnetcore"  -p test-plan

Expected behavior runtime param should support the dotnetcore stuff

[panchagnula]

CLI uses the API to verify the list of supported runtimes before an app is created currently the API has a known issue where dotnetcore is not listed as a supported runtime for windows you can verify this by running the command az webapp list-runtimes - once the API fix rolls out this will automatically work. Closing this since this is not a CLI issue.

so is the recommended way to create a dotnet core webapp to do it on a linux host???
