How can I disable the IIS Express launch profile for ASP.NET Core?

Question

I'm writing an ASP.NET Core app (on the full .NET Framework) that uses WebListener, rather than Kestrel.¹ I'm using Visual Studio 2015 with Update 3, and ".NET Core 1.0.1 tools Preview 2" (the latest VS tooling on the download site as of this writing).

Because I'm using WebListener, and because WebListener is not compatible with IIS Express, I would like to disable the "IIS Express" launch profile in Visual Studio, so that when my teammates open this solution, their Visual Studios will default to running the console app instead of IIS Express, and they'll be able to just hit Run and not get errors.

But so far, I haven't been able to rid VS of the "IIS Express" launch profile. The Project Properties > Debug tab lets me edit the list of profiles, but when I select the "IIS Express" profile, the "Delete" button is disabled. If I edit launchSettings.json directly, and delete the "IIS Express" element from under "profiles", the File > Save operation silently inserts the "IIS Express" profile back into the JSON that it saves to disk!

Apparently Microsoft really wants to always have an "IIS Express" launch profile, even though it isn't necessarily compatible with all ASP.NET Core projects. But it's worth asking: Has anyone found a way to disable the "IIS Express" launch profile in an ASP.NET Core project, and have only the self-host option(s) in the launch-profile selector?

_{¹ For the curious, I'm using WebListener because it will let me self-host in a Windows service and still support NTLM authentication, on a machine without IIS installed. Kestrel only supports NTLM when it's hosted in IIS, not when it's self-hosted.}

UPDATE:

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

Initial answer:

As mentioned in comments in ssmith answer, Visual Studio keeps restoring the settings on restart.

Since I could not find a better solution, I just denied the write permissions on launchsettings.json for Visual Studio. I left the instructions in my other answer for similar question, here is just a copy&paste:

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

Hope it helps.
