问题描述

我今天刚刚开始在应用程序启动时看到这个异常，该应用程序已投入生产 3 年.

I have just today started seeing this Exception out in the wild on application launch with an app that has been in production for 3 years.

System.TypeInitializationException: The type initializer for 'MS.Win32.Penimc.UnsafeNativeMethods' threw an exception. ---> System.Runtime.InteropServices.COMException: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

显然，一些使用 VS2017 并获得安装了 .NET 4.7 的 Windows 更新的开发人员也遇到了此崩溃问题，目前建议的解决方法是关闭触控支持.

Apparently, some developers using VS2017 who got a Windows update that installed .NET 4.7 have been getting this crash as well, it appears the recommended workaround for now is to turn touch support off.

对于我的应用程序，这并不理想.有没有其他人遇到过这种情况，并找到了任何其他解决方法?

With my application, this is not ideal. Has anyone else run into this, and found any other sort of workaround?

推荐答案

更新:微软现已在 手动更新(如 Jürgen 所述)，我个人会坚持使用该解决方法，直到自动更新修复，因为要让每个用户都安装手动更新会做很多工作.<小时>这显然是 .Net 4.7 中的一个错误，它会影响具有触摸输入设备的 Windows 7 和 8/8.1 系统.因此，人们可以希望微软在未来的更新中解决这个问题.同时，保留完整功能的唯一方法是卸载并隐藏更新.

Update: Microsoft has now fixed this problem in a manual update (as noted by Jürgen), personally I will stick with the workaround until the fix is in the automatic update because it would be a lot of work to make every user install a manual update.

如果应用程序是使用 4.6 或更高版本编译的，则其他选项是在 app.config(如您的链接中)或代码中禁用 stylys 和触摸支持.您没有具体说明为什么这不理想，但我认为需要这些功能?请注意，禁用并不意味着每个应用程序都无法通过触摸设备使用，而是它们仅使用可通过鼠标访问的功能.更新:显然，没有鼠标的触摸设备用户在使用需要滚动的 UI 时会遇到问题.

Other option is disabling the stylys and touch support either in app.config (like in your link) or in the code if the app is compiled with 4.6 or newer. You didn't specify why that is not ideal but I assume those features are needed? Notice that the disabling doesn't mean that every app is unusable with touch devices, but rather that they only use features that are accessible with a mouse. Update: Apparently touch device users without a mouse will have trouble using UI that requires scrolling.

这里是那些来这里寻求快速修复的人的代码示例:

Here's the code examples for those who come here seeking quick fix:

在 App.config 中(适用于使用任何框架版本编译的应用)

In App.config (works with apps compiled with any framework version)

<configuration>
  <runtime>
    <AppContextSwitchOverrides value="Switch.System.Windows.Input.Stylus.DisableStylusAndTouchSupport=true" />
  </runtime>
</configuration>

在代码中(使用 .Net Framework >= 4.6 编译时)

In code (when compiled with .Net Framework >= 4.6)

protected override void OnStartup(StartupEventArgs e)
{
    AppContext.SetSwitch("Switch.System.Windows.Input.Stylus.DisableStylusAndTouchSupport", true);
    base.OnStartup(e);
}
