我无法理解如何为工作角色设置 gcAllowVeryLargeObjectsruntime 参数。我在 app.config 中设置了这个婴儿车。但它不起作用。据我了解，我需要以某种方式在 wotker 主机的配置文件中对其进行配置。

更新：基于答案的最终解决方案

服务定义.csdef

<WorkerRole name="XXX" vmsize="Standard_D4">
<Startup>
  <Task commandLine="myStartup.cmd" executionContext="elevated" taskType="simple" >
    <Environment>
      <Variable name="yyy" value="yyy" />
    </Environment>
  </Task>
</Startup>

下一个文件应作为内容添加到工作项目，并始终复制本地

查看http://blogs.msdn.com/b/cie/archive/2013/11/14/enable-server-gc-mode-for-your-worker-role.aspx，它使用启动脚本来启用服务器 GC担任工人角色。您应该能够轻松地对其进行修改以更改 gcAllowVeryLargeObjectsruntime 属性。
