I have a Windows Service (created using this tutorial ). And I am trying to run an IAsyncOperation : var uri= new Uri(@"uri/to/second/app"); var options = new LauncherOptions { TargetApplicationPackageFamilyName = "second-app-guid" }; var results = await Launcher.LaunchUriForResultsAsync(uri, options); However, I get the following error from the await : The type 'IAsyncOperationWithProgress<,>' is defined in an assembly that is not referenced.
