asp.net-mvc - 将 MVC 网站部署到 Azure

Question

将新的 MVC 3 Web 应用程序部署到 Azure 时遇到错误。尽管该站点似乎可以正常工作，但存在角色初始化错误，这意味着 VS2010 的部署永远无法完成。 (参见下面的输出。)

我怀疑 Mindscape.Lightspeed.Web 程序集依赖于 MVC 2。但我认为以下配置部分会覆盖它。

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="3.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

您可以通过从开发系统中卸载 MVC 2 然后在开发结构中运行来使用 Azure 项目模拟此过程。

我该如何解决这个问题？

Answer 1

程序集重定向应该没问题，但不要忘记您可能需要在多个文件中配置它:

• Web.config
• View \Web.config
• WaIISHost.exe.config

您需要确保修改这两个 Web.config 文件。如果您从 WebRole.cs 文件调用 LightSpeed 程序集，我建议您创建一个名为 WeIISHost.exe.config 的新文件，添加重定向并将其设置为始终复制到输出目录。这是必需的，因为 WebRole 现在使用 full IIS .
