Unable to connect to the configured developer web server RRS feed

  • Question

  • I am trying to upgrade a asp.net  project from VS2010 to VS2015. on a new Windows 10 PC (64 bit) I have installed VS2015.

    When I create a new website on this PC using VS2015, and debug it, there is no issue. However when I open an old VS 2010 project and try to debug  it I get the error  "Unable to connect to the configured developer web server" . Please note that the project builds successfully. I have tried all of the solutions I have found on the web without success 

    Not using proxy server

    netsh command

    deleting IE express folder 

    Changing the port in the solution file

    There was one six step solution using tools/External Tools which referenced webdev.webserver.exe but that file does not exist on my machine.

    In any case the issue seems to be with the 2010 project as new projects debug without issue

    Any Help would be apprecited

  • I would recommend always having a backup of the project, in this case for VS2010 so if something goes wrong you have a backup be it making a copy of the project or using a flavor of source control such as TFS. I believe the online version would suit your needs (we use on prem version).
