The way to launch Windows apps is to use Launcher.LaunchUriAsync.

// The URI to launch
string uriToLaunch = @"cameracapture:CaptureImage?folder=C%3A%5C%5CMyImages";

// Create a Uri object from a URI string 
var uri = new Uri(uriToLaunch);

// Launch the URI
async void DefaultLaunch()
{
   // Launch the URI
   var success = await Windows.System.Launcher.LaunchUriAsync(uri);

   if (success)
   {
      // URI launched
   }
   else
   {
      // URI launch failed
   }
}

For this to work you will need a URI scheme for your app. To handle a URI association, specify the corresponding URI scheme name in the app manifest file. Go to your app’s package.appxmanifest file and navigate to the Declarations tab. You want to add a new declaration of type ‘Protocol’ and you’ll need to specify the name property which will be the actual URI protocol you want your app to handle. e.g. cameracapture.

To handle the incoming parameters override the OnActivated method in the App.xaml.cs code behind:

protected override void OnActivated(IActivatedEventArgs args)
{
    if (args.Kind == ActivationKind.Protocol)
    {
        var eventArgs = args as ProtocolActivatedEventArgs;
        if (eventArgs != null)
        {
            var uri = eventArgs.Uri;
            tempUri = System.Net.HttpUtility.UrlDecode(uri.ToString());

            // URI association launch for cameracapture.
            if (tempUri.Contains("cameracapture:CaptureImage?folder="))
            {
                // Get the folder (after "folder=").
                int folderIndex = tempUri.IndexOf("folder=") + 7;
                string folder = tempUri.Substring(folderIndex);

                // Do something with the request
            }
        }
    }
}
