.NET MAUI 无法绑定到目标方法，因为其签名与委托类型的签名不兼容

问题描述 投票：0回答：1

当我启动应用程序时，它崩溃并出现异常：

Cannot bind to the target method because its signature is not compatible with that of the delegate type
。初始屏幕上出现错误。这是我得到的整个日志：

**System.ArgumentException:** 'Cannot bind to the target method because its signature is not compatible with that of the delegate type.'

**System.ArgumentException:** 'Cannot bind to the target method because its signature is not compatible with that of the delegate type.'

[AppCenterXamarinCrashes] Unhandled Exception from source=AppDomain

有人遇到同样的问题吗？我不知道在哪里寻找崩溃...

P.S 该应用程序适用于 iOS

c# .net xamarin xamarin.android maui

嗯，根据你的评论，作为维基答案：

当我启动应用程序时，它崩溃并出现异常：

Cannot bind to the target method because its signature is not compatible with that of the delegate type
。

将构建从 

bundle
更改为 
apk
可以暂时避免该问题。

关于

bundle
和
apk
，你可以看这个案例：apk（.apk）和app bundle（.aab）之间的区别。

Google 使用应用程序包为每个用户的设备配置生成和提供优化的 APK，因此他们只下载运行应用程序所需的代码和资源。因此，用户可以获得更小、更优化的下载。

应该是VS在构建bundle时删除了一些代码和资源，导致错误。
