Wpf TaskDialog引发异常：需要版本6中的comctl32.dll

我正在开发一个现代WPF应用程序。我想使用TaskDialog，但总是会出现常见错误：

TaskDialog功能需要加载comctl32.dll的版本6，但 内存中当前加载了不同的版本

我试图添加一个清单（它已经包含正确的comctl32.dll所需的依赖项），并在项目属性中将其设置为默认清单

它仍然抛出此异常：-/

我的应用程序是这样构建的： 它是一个启动应用程序（普通Windows应用程序，非wpf）。它只有“Program.cs”作为入口点。它在那里动态加载真实的应用程序（它是一个库，而不是WPF应用程序项目）。它调用启动应用程序的启动方法

效果很好，但我总是遇到这个例外。我想这是因为这个启动系统。。。但有什么可能的解决办法来修复它呢

非常感谢：）

也许我的解决方案会对你有所帮助

我的C#“应用程序”是一个类库/dll，用作WIX的自定义操作。我想要一个TaskDialog而不是MessageBox，但我遇到了与您相同的异常，据我所知，清单文件不适用于C#类库。我必须使用多种方法来让我的代码加载正确版本的comctl32.dll

我刚开始工作，所以我的代码有点凌乱和油腻

运行程序的*.exe版本，而不是Visual Studio*.vshost.exe版本

要在Visual Studio中执行此操作，请禁用“调试/启用调试器/启用Visual Studio宿主进程”中的标志。

我发现，如果您使用“RequireAdministrator”权限运行，它会引发异常，但如果权限为“AsInvoker”，则不会引发异常。只是我的观察。如果你的应用程序需要管理员权限，那么我很困惑

你为什么要这么做？为什么不让一个常规的WPF应用程序由

System.Windows.application

启动呢？我猜winforms（或者你之前加载的任何东西）正在加载一堆WPF不关心的古老垃圾。好吧，这个系统是我之前遇到的一个bug的一部分。我刚改变了系统。它现在通过一个真正的WPF项目启动。还是不行。如果我激活“系统自己的调试”，我不会得到任何执行选项，对话框将打开。唯一的错误是：缺少图标：-/这可能是MS Api代码包中的一个问题吗？您是正确的，这是Api本身的一个错误：可能与我得到的异常重复，入口点“TaskDialog”在comctl.dll中找不到：-/我也不喜欢这样的事实，即这种方式锁定了设置进度条或其他控件的可能性：-/但感谢您的回答：）我还发现了这样一个问题：因此，可能这是Visual Studio本身的一个缺陷。正如我所说，在发布模式下，它工作得很好（唯一的问题是缺少图标）..@Razer对于进度条之类的东西，您必须使用TaskDialogIndirect。在\source\WindowsAPICodePack\Core\Interop\TaskDialogs\TaskDialogNativeMethods.cs中查看该Windows®API代码包的源代码。但是它要复杂得多，所以我没有一个简单的解决方案。至于例外情况，我不知道发生了什么。确保您的DllImport线路与步骤2中的线路完全相同。如果已经是这样了。。。那么我不确定：（.不客气！使用上的EnableThemingScope类，因为它已修复了在现已失效的kb/830033链接中发现的内容。另请参见此处：似乎是问题的合理答案…只要我仍然能够调试应用程序，这应该是一个可能的修复。我将很快对其进行测试。好的，这很奇怪…现在它工作正常。我没有触摸该项目大约半年。现在它运行良好，无需禁用托管进程。可能问题已通过许多Windows/Visual Studio更新之一修复。
