我试图在安装了VS2015 Update1的TFS 2013 Build Server上构建PCL库（带有project.json）。
未恢复PCL库的Nuget包（Mirosoft.NETCore和Microsoft.NETCore.Portable.Compatibility）。
我收到错误
Properties\AssemblyInfo.cs (9): The type or namespace name 'AssemblyTitle' could not be found (are you missing a using directive or an assembly reference?)
Properties\AssemblyInfo.cs (17): Predefined type 'System.String' is not defined or imported

第一次尝试是在$ slnDir $ .nuget \ nuget.exe中启用自动包恢复。这适用于visual studio，但不适用于TFS Build。
所以我更改了TFS构建定义以构建我的 build.proj 而不是.sln文件。
它恢复了.NET 4.6类库的nuget包，但不恢复我的PCL库
build.proj

nuget.exe restore说：packages.config中列出的所有软件包都已安装。但是，我的问题是从project.json
