WPF MahApps.Metro嵌入式DLL资源不能正常工作

我的问题是MahApps.Metro和MahApps.Metro.IconPacks的嵌入式dll工作不正常。WPF MahApps.Metro嵌入式DLL资源不能正常工作

使用Visual Studio调试器来检查它们是否正在加载，它工作正常。如果它无法加载它们，程序会抛出一个xaml异常。

但由于某些原因，合并的ResourceDictionaries在运行时不起作用。

（正如你所看到的文字颜色是不同的，它缺少右侧的图标=>不加载的样式。）它看起来像

如果在程序的目录中提供了两个Dll，则为第一张图片。

此代码的工作对我来说：（添加的所有库，嵌入式资源和集合tartup对象）

public class Program 
    { 
     private static Assembly ExecutingAssembly = Assembly.GetExecutingAssembly(); 
     private static string[] EmbeddedLibraries = 
      ExecutingAssembly.GetManifestResourceNames().Where(x => x.EndsWith(".dll")).ToArray(); 
     [STAThreadAttribute] 

     public static void Main() 
     { 

      AppDomain.CurrentDomain.AssemblyResolve += CurrentDomain_AssemblyResolve; 

      App.Main(); 

     } 
     private static Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args) 
     { 
      // Get assembly name 
      var assemblyName = new AssemblyName(args.Name).Name + ".dll"; 

      // Get resource name 
      var resourceName = EmbeddedLibraries.FirstOrDefault(x => x.EndsWith(assemblyName)); 
      if (resourceName == null) 
      { 
       return null; 
      } 

      // Load assembly from resource 
      using (var stream = ExecutingAssembly.GetManifestResourceStream(resourceName)) 
      { 
       var bytes = new byte[stream.Length]; 
       stream.Read(bytes, 0, bytes.Length); 
       return Assembly.Load(bytes); 
      } 
     } 
    }
