我正在尝试将Microsoft Cognitive Service Face API集成到我的Xamarin Forms应用程序中。我已经在我的 PCL 中安装了Microsoft.ProjectOxford.Common.DotNetStandard Version="1.0.0"Microsoft.ProjectOxford.Face" Version="1.4.0"。但是每次我尝试编译代码时，我都会收到一个错误
对于 iOS，我得到：
xxx.iOS/MTOUCH: Error MT2002: Failed to resolve "Microsoft.ProjectOxford.Face.IFaceServiceClient" reference from "Microsoft.ProjectOxford.Face, Version=1.4.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" (MT2002)
对于安卓，我得到：
/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets(2,2): Error: Exception while loading assemblies: System.IO.FileNotFoundException: Could not load assembly 'Microsoft.ProjectOxford.Face, Version=1.4.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Perhaps it doesn't exist in the Mono for Android profile?
File name: 'Microsoft.ProjectOxford.Face.dll'

Xamarin Forms ： 3.0.0.482510. 有人可以帮忙吗？
我认为这是你的问题：
我已经安装了Microsoft.ProjectOxford.Common。DotNetStandardversion="1.0.0"， Microsoft.ProjectOxford.Face" version="1.4.0" in my个人电脑
您正在尝试将 .NET 标准库安装到 PCL 中，该库不保证兼容。你希望将 PCL 升级到 .NET 标准库(无论如何，这都是一个好主意(，或者安装较旧版本的 NuGet 包。
