WinJS System.Launcher只能在調試模式下工作

Question

下面的代碼在調試模式（F5）下運行時完美地工作..但是當部署（作爲應用程序磁貼）或運行時沒有調試器（ctl + f5）時，它確實工作不是正常工作。

行爲預期/工作時間：點擊瓦片立即啓動蒸汽URL鏈接，而不會顯示html頁面。

行爲收到/不工作：點擊瓦片啓動應用程序，只渲染HTML頁面，並從不啓動蒸汽網址。

var mydefs = new Object(); 
mydefs = { url: 'steam://rungameid/200710' }; 

function launch(url) { 
    var uri = new Windows.Foundation.Uri(url); 

    Windows.System.Launcher.launchUriAsync(uri).then(
     function (success) { 
      if (success) { 
       // File launched 
       window.close(); 
      } else { 
       // File launch failed 
      } 
     }); 
} 

(function() { 
    "use strict"; 

    WinJS.Binding.optimizeBindingReferences = true; 

    var app = WinJS.Application; 
    var activation = Windows.ApplicationModel.Activation; 

    app.onactivated = function (args) { 
     if (args.detail.kind === activation.ActivationKind.launch) { 
      launch(mydefs.url); 

      args.setPromise(WinJS.UI.processAll()); 
     } 
    }; 

    app.oncheckpoint = function (args) { 
     window.close(); 
    }; 

    app.start(); 
})();

看起來像是一個計時問題。以下作品適合我作爲瓷磚

(function() { 
    "use strict"; 
    var mydefs = new Object(); 
    mydefs = { url: 'steam://rungameid/200710' }; 

    WinJS.Namespace.define("Steam", { 
     launch: function launch(url) { 
     var uri = new Windows.Foundation.Uri(url); 

     Windows.System.Launcher.launchUriAsync(uri).then(
      function (success) { 
       if (success) { 
        // File launched 
        window.close(); 
       } else { 
        // File launch failed 
       } 
      }); 
      } 
    }); 


    WinJS.Binding.optimizeBindingReferences = true; 

    var app = WinJS.Application; 
    var activation = Windows.ApplicationModel.Activation; 

    app.onactivated = function (args) { 
    if (args.detail.kind === activation.ActivationKind.launch) {     
     setTimeout('Steam.launch("steam://rungameid/200710");', 2000); 
     args.setPromise(WinJS.UI.processAll()); 
    } 
    }; 

    app.start(); 
})();
