Error when debugging: Unable to start debugging on the web server. The object invoked has disconnected from its clients RRS feed

  • Question

  • I use Visual Studio 2013, .NET 4.5.1.
    I have a Web API 2 application.

    I debugged my application many time.
    Somehow, I cannot debug it anymore.

    I get the following error (On F5):

    **Unable to start debugging on the web server. The object invoked has disconnected from its clients**

    The only thing is new, is that I connected my solution to local Git. I'm not sure how related it is.

    Help please?

  • Hi Janiv,

    Thank you for posting in the MSDN forum.

    Just to make this issue clearly, do you mean that you debug a web app locally in your VS2013?

    If you create a simple web app, could you debug it well? If other apps work well, so we could make sure that it is not the VS IDE issue.

    Since you get the error when you debug your app, how about running your app with Ctrl +F5 (Start without debugging)? If it still has this issue, I’m afraid that it is your app issue. If so, you would discuss this issue with your team members.

    1. Please restart your machine and re-open your VS.
    2. Please clean and rebuild your app.

    In addition, if it worked well before, please check whether you change anything in your project/VS IDE settings. Maybe you could run your VS in safemode/as the admin, check it again.

    Best Regards,
