ISS Express, VS 2015 Update 3, and .Net Core RRS feed

       For the past five days I have been fighting an issue with IIS Express not working correctly.   As of right now I have uninstalled Visual Studio 2015 3 times, along with every component.  Ran CC Cleaner on the registry until it came back clean, and done a refresh on the machine.  Yes I went nuclear on it.  Unfortunately I have gotten no where's near being able to debug my application anymore.  Originally I was getting a AspNetCoreModule error with IIS Express.  I finally found the offending .dll and placed it in both the IIS Express folder for Program Files and Program Files (x86).  Now I am getting unable to connect to web server 'IIS Express'.

    I have followed every step in the following articles with no success what so ever:





    I have gone to my to the following directory and deleted the applicationhost.config file (C:\Users\Michael.Mastro2\Source\Workspaces\Lotro\Lotro.Application\.vs\config)

    I have uninstalled and reinstalled IIS Express 10 about 4 times after the Visual Studio uninstall / reinstalls.

    I have uninstalled and reinstalled Microsoft .Net Core 1.0.1 - VS 2015 Tooling Preview 2 ( about 8 times.

    I have also tried to switch from IIS Express to the project via the Debug tab in the Properties of the application, and that still does not work.

    I am at wits end, this is driving me crazy.  Does anyone have any thoughts on how I set this up incorrectly?

    Hi Mike,

    You could consider using Visual Studio 2017 with the ASP.NET and web development and .NET Core cross-platform development workloads installed to create ASP.NET Core 1.1 web applications.

    Best Regards,
