nuget package 管理器不提供旧版本的 package

Question

I inherited some old legacy code which I'm trying to build, but I'm missing some specific dlls. In particular, I need version 4.0.0.0 of System.ComponentModel.Composition , but the Nuget Package Manager options only go down to 4.5.0. Why is this, and how can I get the version I need?

Here is the line specified by the Web.config file I inherited.

<add assembly="System.Net.Http.WebRequest, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />

Answer 1

According to your description, you can refer to the following steps to find the dlls you need:

1. Right-click on the References under your project in Solution Explorer.
2. Choose Assemblies and search System.ComponentModel.Composition, System.Net.Http.WebRequest
3. Check them and add them to the project.
