Build Nuget.Server

Container needs of the project company, small study to net frameworkupgrade the project to be net standard 2.0, but in the package upload nupkglater, vs the nuget plug-in does not recognize the dependency display Unsupported.

Xiao Bian suspected cause of the company's nuge server version is too low, then by nuget installed the latest Nuget.Server. When the project started, throwing 500 error:

[FileLoadException: 未能加载文件或程序集“NuGet.Server, Version=3.1.2.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35”或它的某一个依赖项。找到的程序集清单定义与程序集引用不匹配。 (异常来自 HRESULT:0x80131040)]

Because nuget.server package in question, Xiao Bian finally downloaded the latest source code Nuget.Server

Local compile and run properly, but after the release of web projects deployed on the server, run the project returns a 500 error.

异常信息: 
    异常类型: NullReferenceException 
    异常消息: 未将对象引用设置到对象的实例。

The log is determined: not relevant target injection start of the project, resulting in IOC when performing the analysis, the null pointer exception occurs.

Finally found the cause of the error in NuGetODataConfig.cs file. The assertion if deleted, re-released project, Nuget.Server run successfully, vs can properly identify the dependencies

// The consuming project executes this logic with its own copy of this class. This is done with a .pp file that is
// added and transformed upon package install.
