MTOUCH:错误MT0009:加载程序集时出错：grpc_csharp_ext.x64.dll（MT0009）

我在使用Visual Studio for Mac和iOS项目时遇到生成错误。它也出现在Mac上的Android项目和Windows 10上Visual Studio 2019的iOS项目中

我能够在iPhone8上运行这个项目，当时它是“干净的”，在我把任何代码放进去之前

以下是错误：

/Users/shinehah/VSProjects/iOSAppSpeechToText01/iOSAppSpeechToText01/MTOUCH: Error MT0009: Error while loading assemblies: /Users/shinehah/.nuget/packages/grpc.core/1.18.0/runtimes/win/native/grpc_csharp_ext.x64.dll (MT0009) (iOSAppSpeechToText01)

以下是警告：

该错误最后发生在警告之后

我没有添加任何代码。唯一的区别是我安装了Google.Cloud.Speech.V1

这就是我在一个新的清洁项目后改变的一切

---

我曾尝试使用Google.Cloud.Speech.V1 1.0.1软件包而不是1.1.0，但我也遇到了同样的错误。

如果你是在Iphone 8上开发的，你有什么理由想使用Google Cloud Speech在C#/.net中编写文本，而不是使用苹果自己的语音API？我怀疑你会有很多Mono的疑难解答（你的问题乍一看像是Mono的配置问题）。@paisanco我不知道苹果有语音到文本的API。它叫什么？@paisanco我找到了。这叫演讲。哼！如果你是在iPhone8上开发的，你有没有理由想使用谷歌云语音来在C#/.net中编写文本，而不是使用苹果自己的语音API？我怀疑你会有很多Mono的疑难解答（你的问题乍一看像是Mono的配置问题）。@paisanco我不知道苹果有语音到文本的API。它叫什么？@paisanco我找到了。这叫演讲。哼！
