有谁知道Microsoft OData客户端是否以及如何在Xamarin Droid上运行？
它是NuGet包’Microsoft.OData.Client’.
它在Console应用程序上运行良好,即使汇编程序包仅包含在PCL项目中也是如此.
在Xamarin上运行时,这就是我得到的：

有人在那里提出建议吗？
问候,

解决方法
我不相信这个软件包支持Xamarin – 从
nuget page开始：
Targets .NET Core 5,and .NET Portable Lib with support for .NET 4.0,SL 5.0,Win Phone 8,Win Phone 8.1,and Win 8.
我建议向库的开发者提出一个问题,以获取更多相关信息,因为如果它支持Xamarin,它可能是一个错误：

组件商店中有以下组件应该可以使用,但它已经有一段时间了,因为它已经更新：
