Question

我有一个Web应用程序。当使用msbuild构建，然后部署到IIS时，它声称缺少对System.Web.Mvc版本4.0.0.0的引用问题是，它不会也不应该引用mvc程序集。我如何找出这个参考的来源？

感谢。

从IIS输出：

Server Error in '/Content' Application.

查看应用程序的web.config文件，特别是system.web中的编译部分。

以下是配置文件的这一部分查找MVC 3应用程序的内容。确保你没有在那里添加MVC 4的引用：

<compilation debug="true" targetFramework="4.0">
  <assemblies>
    <add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add assembly="System.Web.WebPages, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
  </assemblies>
</compilation>

Answer 2

在app.config或web.config中检查以下内容。我的项目是使用MVC 3.0并在配置中有以下内容。大概是从更新到4.0的开发版然后降级回3.0并且没有正确清理它。

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentAssembly>
            <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" culture="neutral" />
            <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
        </dependentAssembly>
    </assemblyBinding>
</runtime>
