I want to build a local development environment for Azure Static Web Apps using SWA CLI. The Client is a Blazor WASM.

I installed SWA CLI successfully using the command:
npm install -g @azure/static-web-apps-cli

The Blazor client is working fine when started from Visual studio using F5

Running swa init command produced this file swa-cli.config.json

{
  "$schema": "https://aka.ms/azure/static-web-apps-cli/schema",
  "configurations": {
    "blazor-app3": {
      "appLocation": ".",
      "outputLocation": "bin\wwwroot",
      "appBuildCommand": "dotnet publish -c Release -o bin",
      "run": "dotnet watch run",
      "appDevserverUrl": "http://localhost:5050"
    }
  }
}```



When I run 'swa start' command I get this

`
C:UsersemadsourcereposBlazorApp3BlazorApp3>swa start

The browser is opening localhost:5050 

The problem is : If I try to open the localhost:4280 to see the "emulated" site. I always get an error ERR_CONNECTION_REFUSED
