asp.net - 无法加载文件或程序集 'System.Web.Mvc'。如何使用正确的引用？

Question

我有一个基于 ASP.NET Web 表单的应用程序，它也支持 MVC 5。我在项目中包含了 MVC 5 API Controller ，为此我必须将 Json 从 4.5 版升级到 7.0。在启动应用程序时进行这些更改后，我收到以下错误:

Could not load file or assembly 'System.Web.Mvc' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

我检查了 System.Web.Mvc 的引用资料.在属性对话框中运行时版本是 v4.0.30319版本是 5.0.0.0 .在 web.config 中，程序集设置如下:

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

如何升级 System.Web.Mvc 的版本以指向正确的程序集？

Answer 1

错误是由于不正确的绑定(bind)引起的。我变了:

<dependentAssembly>
    <assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.2.3.0" />
  </dependentAssembly>

到

  <dependentAssembly>
<assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.0.0.0" />

现在可以了。
