ADO.NET 数据服务中的自定义逻辑和代理类

我刚刚读过“在 ADO.NET 数据服务中注入自定义逻辑”，我的下一个问题是，如何让 [WebGet] 方法显示在客户端中代理类？当然，我可以使用 WebClient 直接（RESTful）调用它，但我认为 ADO.NET 数据服务中的强类型功能会自动神奇地“隐藏”我。

所以这里我们有：

public class MyService : DataService<MyDataSource>
{
    // This method is called only once to initialize service-wide policies.
    public static void InitializeService(IDataServiceConfiguration config)
    {
        config.SetEntitySetAccessRule("Customers", EntitySetRights.AllRead);
        config.SetServiceOperationAccessRule("CustomersInCity", ServiceOperationRights.All);
    }

    [WebGet]
    public IQueryable<MyDataSource.Customers> CustomersInCity(string city)
    {
        return from c in this.CurrentDataSource.Customers
               where c.City == city
               select c;
    } 

}

如何让 CustomersInCity() 显示在我的客户端类定义中？

I've just read "Injecting Custom Logic in ADO.NET Data Services" and my next question is, How do you get your [WebGet] method to show up in the client-side proxy classes? Sure, I can call this directly (RESTfully) with, say, WebClient but I thought the strong typing features in ADO.NET Data Services would "hide" this from me auto-magically.

So here we have:

public class MyService : DataService<MyDataSource>
{
    // This method is called only once to initialize service-wide policies.
    public static void InitializeService(IDataServiceConfiguration config)
    {
        config.SetEntitySetAccessRule("Customers", EntitySetRights.AllRead);
        config.SetServiceOperationAccessRule("CustomersInCity", ServiceOperationRights.All);
    }

    [WebGet]
    public IQueryable<MyDataSource.Customers> CustomersInCity(string city)
    {
        return from c in this.CurrentDataSource.Customers
               where c.City == city
               select c;
    } 

}

How can I get CustomersInCity() to show up in my client-side class defintions?
