Launch Profile Initializer: Unable to parse the launchSettings.json file

Question

Microsoft Visual Studio shows the following error box:

Launch Profile Initializer

Unable to parse the launchSettings.json file.

Where to find which project is causing this issue? There is no detailed information in the Output window.

Answer 1

Your launchSettings.json has to contain at least applicationUrl e.g.

{
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:55555",
      "sslPort": 44395
    }
  }
}
