无法加载文件或程序集“ Xamarin.iOS”或其依赖项之一无法验证强名称签名HRESULT：0x80131045

如何解决无法加载文件或程序集“ Xamarin.iOS”或其依赖项之一无法验证强名称签名HRESULT：0x80131045

我已经搜索了，但是找不到解决方案 我在Visual Studio中拥有一个Xamarin Forms App，所以我的解决方案中有5个项目：

awk 'NR==FNR { arr[$1]="1" } NR != FNR { if (arr[$1] == "") { print $0 } } ' file2 file1

我仅使用MagCoils，MagCoils.Android和MagCoils.WebService ...从未测试过iOS和UWP。 将窗体从Visual Studio 2017社区切换到Visual Studio 2019社区并升级一些程序包后....当我将MagCoils.WebService设置为StartUp项目并使用Chrome对其进行调试时，我在此页面中运行错误，无法加载文件或程序集'Xamarin。 iOS”或其依赖项之一。

我不知道如何继续解决此错误，我对Xamarin，C＃和WebSerivice还是陌生的，但是此项目/解决方案在升级之前始终可以正常工作，但是我不知道哪个升级原因是我的问题。
