问题描述

我试图 Microsoft.AspNet.WebApi 的NuGet包添加到C＃类库项目。 这里的的情况下，项目源$ C ​​$ C 你需要它。

I am trying to add Microsoft.AspNet.WebApi Nuget Package to a C# Class Library Project. Here's the Project source code in case you need it.

当我在的NuGet包管理器控制台在Visual Studio 2013中执行以下命令（它有最新的.NET 4.5的吧）

When I execute the following command in the Nuget Package Manager Console in Visual Studio 2013 (it has latest .NET 4.5 in it)

PM> install-package Microsoft.AspNet.WebApi ErrandBoy.Web.Common

我收到以下错误。

I get the following Error.

PM> install-package Microsoft.AspNet.WebApi ErrandBoy.Web.Common

特定的错误行如下。这似乎是它的尝试添加引用添加'Microsoft.AspNet.WebApi.Client 5.2.2

我以前从来没有得到这样的错误。我没有看到这个SO溢出问题类似的错误=> Error在安装ASP.NET身份2 的样品，但一个一直无人接听。

I've never gotten such an error before. I did see a similar error on this SO Overflow question => Error on installing ASP.NET Identity 2 Samples but that one has no answer.

推荐答案

我刚做了同样的问题。我通过手动添加 System.Net.Http 来引用解决它。然后，它抱怨别人，而是由一个手动一位代表补充他们之后，我能够用的NuGet安装软件包。

I just had the same issue. I solved it by manually adding System.Net.Http to the references. Then it complained about others, but after adding them manually one by one I was able to install the package with NuGet.
