c# - 无法加载文件或程序集 'System.Web.Mvc' 或其依赖项之一。 2个项目。一次只有一个会工作

Question

所以我的解决方案中有 2 个网站项目(以及许多其他测试/dll 项目)。

项目 A - CMS - 标准 Web 项目(带有一些 Web API 集成)项目 B - 展示网站 - MVC 5。

我构建项目 A 并运行它。它有效，没有意外的错误。然后我构建项目 B。项目 B 工作正常，同样没有意外错误。

我回去查看有关项目 A 的内容，但在运行时出现以下错误。

无法加载文件或程序集“System.Web.Mvc”或其依赖项之一。找到的程序集的 list 定义与程序集引用不匹配。 (HRESULT 异常:0x80131040)

描述:在执行当前网络请求期间发生未处理的异常。请查看堆栈跟踪以获取有关错误及其在代码中的来源的更多信息。

然后我必须构建项目 A 以使其在运行时加载。它有效，但项目 B 有同样的问题。

我进入了项目的/bin/文件夹并观察到一些奇怪的东西。假设我正在查看项目 A 的/bin

如果我构建项目 A，System.Web.Mvc.dll 文件的版本为 5.1.20129.0如果我构建项目 B，相同的 DLL 文件会将其版本后退一步。至 5.0.11001.0

使用此信息，我可以理解为什么会触发错误，因为它认为的版本比那里的版本高。

此外，它没有与我们的 Git 存储库同步，因为没有其他开发人员遇到这个问题。

有人知道这是如何开始发生的吗？可能我该如何解决？
