如何在插件上創建或獲取OrganizationServiceProxy實例

Question

是否有任何方式在插件上創建OrganizationServiceProxy實例？
我想執行EnableProxyTypes方法，將不同於插件程序集的程序集作爲EnableProxyTypes方法的參數傳遞。
因爲我想要有一個程序集文件，它有一個早期的綁定類，並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. 
    }

我建議有這篇文章的讀：

Walkthrough: Build a Plug-in That Connects to Microsoft Dynamics CRM Using Developer Extensions

尤其是下面的代碼片段。

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

... 

using (var crm = new XrmServiceContext(service))
