title: Changing .NetCore App launchSettings.json for deployment on Azure
body: <p>This is my first ever application deployment and I am running into issues with debugging. I tried logging into my app on azure and received this error.</p>
  
  <p><a href="https://i.stack.imgur.com/RgGAM.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RgGAM.png" alt="enter image description here"></a></p>
  
  <p>So I thought it might be my launchSettings.json which is still pointing to development as of the time I deployed the app.</p>
  
  <p>However, I don't know what to change my launchSettings.json to.</p>
  
  <p>This is how it looks </p>
  
  <pre><code>{
   "iisSettings": {
  "windowsAuthentication": false,
  "anonymousAuthentication": true,
  "iisExpress": {
    "applicationUrl": "http://localhost:63990",
    "sslPort": 44376
   }
  },
  "profiles": {
  "IIS Express": {
    "commandName": "IISExpress",
    "launchBrowser": true,
    "environmentVariables": {
      "ASPNETCORE_ENVIRONMENT": "Development"
    }
  },
  "ManagementApp": {
    "commandName": "Project",
    "launchBrowser": true,
    "applicationUrl": "https://localhost:5001;http://localhost:5000",
    "environmentVariables": {
      "ASPNETCORE_ENVIRONMENT": "Development"
     }
    }
   }
  }
  </code></pre>
  
  <p>I need to change this to match something so I can switch from <strong>Development mode</strong> but don't know which setting from Azure goes where</p>
