Visual Studio keeps adding IIS Express back into my launchsettings.json

Question

I am trying to remove the IIS Express profile from my .NET Core launch settings but every time i repoen the solution, Visual Studio adds it back in again. For example, in a new project my launch settings looks like this

{
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:55735/",
      "sslPort": 0
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "MyProject": {
      "commandName": "Project",
      "launchUrl": "http://localhost:5010",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

I remove the IIS sections

{
  "profiles": {
    "MyProject": {
      "commandName": "Project",
      "launchUrl": "http://localhost:5010",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

The solution runs fine. But as soon as I close and reopen the solution the IIS sections reappear.

Any ideas?

This is really annoying, but I guess this is just how it is for now. According to [this discussion](https://github.com/aspnet/Tooling/issues/486) there is some ticket created almost a year ago, but no comments on whether this will be ever fixed/changed. — Ilya Luzyanin, Mar 30 '17 at 14:44

UPDATE:

The issue should be fixed with the latest release (update) of Visual Studio 2017 (version 15.3.0).

Initial answer:

This is not a solution, but an ugly workaround. I figured that if I would just deny permissions to change the launchsettings.json file this will prevent Visual Studio from overwriting it every time. Since this file doesn't change much, it is more or less a satisfying solution for me.

So:

Update your launchsettings.json for the last time.
Close Visual Studio.
Open security settings (right-click on launchsettings.json in Explorer -> Properties -> Security)
Click Advanced -> Change Permissions
Select "Authenticated Users" (or other user group under which Visual Studio is running on your machine) from the "Permissions entries" list and click Edit ->
Check Deny for "Create files / write data" permission.
Click OK in all open dialogs and warnings to save changes.
Reopen Visual Studio and see it fail to do it's update.

Hope it helps.

Thats is indeed an ugly workaround! I'm not sure I can accept this as the answer though. – Kevin Brydon Mar 31 '17 at 15:56
Yeah, you are right. I would probably not accept this either, since this is more like a hack. – Ilya Luzyanin Apr 01 '17 at 16:14

I can confirm that the issue appears to have been resolved in Visual Studio version 15.3.0. Should make development a lot less frustrating from now on! – Kevin Brydon Aug 16 '17 at 14:49

In my case the issue was related to a missing bracket at the end of the file, so Visual Studio was being unable to process it, please check the JSON format is correct.

just check your launch settings file is a valid for JSON format, you should forget a comma or mustache
