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
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:
launchsettings.json
for the last time.Hope it helps.
