我有一个引用Core PCL（Profile111）的Xamarin.Android项目。 Core PCL引用Microsoft.WindowsAzure.Mobile和Microsoft.WindowsAzure.Mobile.SQLLiteStore（见下文）：
<Reference Include="Microsoft.WindowsAzure.Mobile, Version=3.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
<HintPath>..\packages\Microsoft.Azure.Mobile.Client.3.1.0\lib\portable-win+net45+wp8+wpa81+monotouch+monoandroid\Microsoft.WindowsAzure.Mobile.dll</HintPath>
<Private>True</Private>
</Reference>
<Reference Include="Microsoft.WindowsAzure.Mobile.SQLiteStore, Version=3.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
<HintPath>..\packages\Microsoft.Azure.Mobile.Client.SQLiteStore.3.1.0\lib\portable-win+net45+wp8+wpa81+monotouch10+monoandroid10+xamarinios10\Microsoft.WindowsAzure.Mobile.SQLiteStore.dll</HintPath>
<Private>True</Private>
</Reference>
除了这些（作为NuGet包添加，我引用ReactiveUI和Microsoft.Bcl。请参阅packages.config以获取引用包的完整列表：

我在VSTS中遇到编译问题，但在我的框中没有本地编译问题。在我的盒子上，我可以在Debug或Release配置中正常编译。在VSTS上，我收到以下警告/错误：

在VSTS上构建时，我不知道它在哪里引用了3.0.0.0版本。请帮助和谢谢。
更新 为了隔离问题的来源，我向Microsoft.WindowsAzure.Mobile和Microsoft.WindowsAzure.Mobile.SQLLiteStore引用添加了引用别名，如下所示：
<Reference Include="Microsoft.WindowsAzure.Mobile, Version=3.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
<HintPath>..\packages\Microsoft.Azure.Mobile.Client.3.1.0\lib\portable-win+net45+wp8+wpa81+monotouch+monoandroid\Microsoft.WindowsAzure.Mobile.dll</HintPath>
<Private>True</Private>
<Aliases>core</Aliases>
</Reference>
并在代码中：
extern alias core;
using core.Microsoft.WindowsAzure.MobileServices;
using core.Microsoft.WindowsAzure.MobileServices.SQLiteStore;
using core.Microsoft.WindowsAzure.MobileServices.Sync;
此举消除了上述错误，但又出现了一个新错误：
C:\Program Files (x86)\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets (1404, 2)
C:\Program Files (x86)\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(1404,2): Error : Exception while loading assemblies: System.IO.FileNotFoundException: Could not load assembly 'Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed'. Perhaps it doesn't exist in the Mono for Android profile?

在我看来，包恢复可能无法正常使用此NuGet。将尝试按照本文中的步骤查看是否可以更正程序包还原：https://docs.microsoft.com/en-us/nuget/consume-packages/package-restore#msbuild-integrated-restore。
