如何将System.Net.Http.Formatting从4.0.0.0更新为5.2.3.0？

修改

尝试Update-Package –reinstall Microsoft.AspNet.WebApi.Client但似乎此数据包不包含System.Net.Http.Formatting

Answer 1

您需要运行以下PM命令来获取System.Net.Http.Formatting程序集。

Install-Package System.Net.Http.Formatting.Extension

更新：

Update-Package System.Net.Http.Formatting.Extension -ProjectName MyProject -Version 5.2.3.0

安装后检查packages.config，应列出

<package id="System.Net.Http.Formatting.Extension" version="5.2.3.0" targetFramework="net452" />

Answer 2

您需要下载并安装ASP.Net MVC 4 here或使用Web platform installer

然后它将在您计算机的以下位置找到

C：\ Program Files（x86）\ Microsoft ASP.NET \ ASP.NET MVC 4 \ Assemblies \ System.Net.Http.Formatting.dll

将System.Net.Http.Formatting从Version = 4.0.0.0更新为Version = 5.2.3.0
