无法加载文件或程序集'System.Web.Mvc'或其依赖项之一。 2个项目。 一次只能工作一个

Question

因此，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（具有某些Web API集成）项目B-显示站点-MVC 5。

我构建项目A，然后运行它。 它可以正常工作，没有意外错误。 然后，我构建了项目B。项目B正常运行，再次没有意外的错误。

我返回查看Project A上的内容，并在运行时收到以下错误。

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

说明：执行当前Web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起源的更多信息。

然后，我必须构建Project A以使其在运行时加载。 它可以工作，但是Project B也有同样的问题。

我进入了Projects的/ bin /文件夹，发现有些奇怪。 说我正在查看项目A的/ bin

如果我生成Project A，则System.Web.Mvc.dll文件的版本为5.1.20129.0。如果我生成Project B，则相同的DLL文件将其版本后退一步。 至5.0.11001.0

使用此信息，我可以理解为什么会引发该错误，因为它认为该版本比那里的版本高。

而且，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此问题。

任何人都知道这是如何开始的吗？ 可能我该如何解决？

右键单击解决方案，然后转到“公共属性”下的“启动项目”，选择“多个启动项目”，选择两个项目。 这将同时运行项目并解决您的问题。
