Can'；t获取.Net嵌入'；s objcgen.exe将Windows上的Visual Studio 2019 Xamarin.IOS项目转换为MacOS上的Xcode项目

我创建了一个hello world Xamarin.ios类库项目。
我添加了Nuget嵌入器4000。
我在Windows 10上的Visual Studio 2019上构建它。
但是当我运行objcgen.exe进行Embeddedinator转换时，我得到以下错误

C:\Users\Doug\.nuget\packages\embeddinator-4000\0.4.0\tools\objcgen.exe --gen=Obj-C --platform=ios --compile --debug  --verbose `embedinnator2 class lib.dll'

“请填写错误报告…”-您这样做了吗？我计划今天填写Microsoft Visual Studio错误报告。在Embeddedinator github上记录问题会更有效
