发布模式下的Xamarin.UWP运行时错误

Question

在发布模式下运行我的Xamarin.Forms.UWP应用程序时，我得到了一个错误。

onecore\com\combase\inc\comcataloghelpers.hpp(64)\combase.dll!00007FFD5E991DAA: (caller: 00007FFD5E990205) ReturnHr(1) tid(6adc) 80040154 Klasse nicht registriert

这发生在App.xaml.cs中自动生成的代码部分中。

protected override void OnLaunched(LaunchActivatedEventArgs e)
        {
            Frame rootFrame = Window.Current.Content as Frame;

            // Do not repeat app initialization when the Window already has content,
            // just ensure that the window is active
            if (rootFrame == null)
            {
                // Create a Frame to act as the navigation context and navigate to the first page
                rootFrame = new Frame();

                rootFrame.NavigationFailed += OnNavigationFailed;

                Xamarin.Forms.Forms.Init(e);

                if (e.PreviousExecutionState == ApplicationExecutionState.Terminated)
                {
                    //TODO: Load state from previously suspended application
                }

                // Place the frame in the current Window
                Window.Current.Content = rootFrame;
            }

            if (rootFrame.Content == null)
            {
                // When the navigation stack isn't restored navigate to the first page,
                // configuring the new page by passing required information as a navigation
                // parameter
                rootFrame.Navigate(typeof(MainPage), e.Arguments);
            }

在这条线内：

rootFrame.Navigate(typeof(MainPage), e.Arguments);

只有当我在发布模式下运行应用程序时，才会发生这种情况，如果在调试中运行，就不会发生错误。

Answer 1

在发布模式下，您必须执行自己加载程序集

// You'll need to add using System.Reflection;

List<Assembly> assembliesToInclude = new List<Assembly>();

// Now, add in all the assemblies your app uses
assembliesToInclude.Add(typeof (ClassInOtherAssembly).GetTypeInfo().Assembly);

// Also do this for all your other 3rd party libraries
Xamarin.Forms.Forms.Init(e, assembliesToInclude);
// replaces Xamarin.Forms.Forms.Init(e);

因此，添加使用1行assembliesToInclude.Add(typeof (ClassInOtherAssembly).GetTypeInfo().Assembly);的每一个第三方类

我通过在我的UWP项目中取消检查“用.NET本地工具链编译”来修正它。但我不确定这是否只是暂时的解决办法
