GetFilesAsync停止工作

我有这段代码GetFilesAsync停止工作

public static class Storage 
{ 
    public async static Task<bool> Exists(string filename) 
    { 
     var folder = await Package.Current.InstalledLocation.GetFolderAsync("Assets"); 
     var _files= await folder.GetFilesAsync(CommonFileQuery.OrderByName).AsTask().ConfigureAwait(false); 

     var file = _files.FirstOrDefault(x => x.Name == filename); 
     return file != null; 
    } 
}

，并从我的Windows 8 Store应用程序调用它;

this.IconExists = this.Game != null && Storage.Exists(this.IconName).Result;

所以，如果我把一个破发点以上线并运行它一步一步来，它的工作原理，但没有突破，只是运行该应用程序会导致应用程序挂起。

一个类似的代码正在工作在几天前的提交;

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Threading.Tasks; 
using Windows.ApplicationModel; 
using Windows.Storage; 
using Windows.Storage.Search; 

namespace eggrr.Core.FileStorage 
{ 
    public class Storage 
    { 
     private IReadOnlyList<StorageFile> _files; 

     public Storage() 
     { 
      _files = GetFilesAsync("Assets").Result; 
     } 

     private async Task<IReadOnlyList<StorageFile>> GetFilesAsync(string relativeFolderPath) 
     { 
      var path = string.Format("{0}\\{1}", Package.Current.InstalledLocation.Path, relativeFolderPath); 
      var folder = await StorageFolder.GetFolderFromPathAsync(path); 
      return await folder.GetFilesAsync(CommonFileQuery.OrderByName).AsTask().ConfigureAwait(false); 
     } 

     public bool Exists(string filename) 
     { 
      var file = _files.FirstOrDefault(x => x.Name == filename); 
      return file != null; 
     } 

     private static readonly Storage _instance = new Storage(); 
     public static Storage Instance { get { return _instance; } } 
    } 
}

任何想法？

似乎这解决了它的问题;

public static class Storage 
{ 
    private static IReadOnlyList<StorageFile> _files; 

    static Storage() 
    { 
     _files = GetFilesAsync("Assets").Result; 
    } 

    private async static Task<IReadOnlyList<StorageFile>> GetFilesAsync(string relativeFolderPath) 
    { 
     var folder = await Package.Current.InstalledLocation.GetFolderAsync("Assets").AsTask().ConfigureAwait(false); 
     return await folder.GetFilesAsync(CommonFileQuery.OrderByName).AsTask().ConfigureAwait(false); 
    } 

    public static bool Exists(string filename) 
    { 
     var file = _files.FirstOrDefault(x => x.Name == filename); 
     return file != null; 
    } 
}
