如何在插件上创建或获取OrganizationServiceProxy实例

Question

是否有任何方式在插件上创建OrganizationServiceProxy实例？
我想执行EnableProxyTypes方法，将不同于插件程序集的程序集作为EnableProxyTypes方法的参数传递。
因为我想要有一个程序集文件，它有一个早期的绑定类，并被一些插件和程序共享。

public void Execute(IServiceProvider serviceProvider) 
    { 
     var context = (IPluginExecutionContext) serviceProvider.GetService(typeof (IPluginExecutionContext)); 
     var factory = (IOrganizationServiceFactory) serviceProvider.GetService(typeof (IOrganizationServiceFactory)); 
     var service = factory.CreateOrganizationService(context.UserId); 

     var proxy = (OrganizationServiceProxy)service; //this doesn't work. an error occurs. 
    }

我建议有这篇文章的读：

尤其是下面的代码片段。

IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory)); 
IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId); 

... 

using (var crm = new XrmServiceContext(service))
