  • "error 0x800700A0" when adding Ad Mediation to "View in Designer" VS 2015

    Hello, I got an error message when trying to add the Ad Mediation to "View In Designer". 

    Short video shows exact problem and what happened.

    Other Details include:
    "System.Exception

    Package could not be registered.

    error 0x800700A0: Windows cannot register the package because an ActivatableClassID with the same name already exists: 'Microsoft.Advertising.WinRT.UI.ManipulationStateChangedEventArgs'. Provide a different name and try again."


    Any help would be greatly appreciated. Thank you.

  • Hey,

    In the "Solution Explorer" under "References" you should remove "Microsoft.AdMediatorWindows81" and reload the designer.

    This should fix it. If not, try to restart the page or VS.
