Question

我正在尝试将Microsoft Cognitive Service Face API集成到我的Xamarin Forms应用中。我已经在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，都会出现错误

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Android，我会得到：

    /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?

Xamarin形式：3.0.0.482510。有人可以帮忙吗？

我认为这是您的问题所在

我已经安装了Microsoft.ProjectOxford.Common。 DotNetStandard 版本=“ 1.0.0”，Microsoft.ProjectOxford.Face“版本=” 1.4.0“ PCL

您试图将.NET Standard库安装到PCL中，但不能保证兼容。您既可以将PCL升级到.NET Standard库（无论如何都很好），或者安装较旧版本的NuGet软件包。

无法添加面部认知服务Nuget
