在Castle.Windsor使用基于任务的客户端操作与WCFFacility

问题描述

我想利用新的基于任务的作战中WCF客户端。我目前使用的WCFFacility如下：

I would like to take advantage of the new task-based operations for a WCF client. I am currently using the WCFFacility as follows:

container.Register(Component
    .For<IAdminService>()
    .LifeStyle.Transient
    .AsWcfClient(new DefaultClientModel()
    {
        Endpoint = WCFHelpers.BasicHttp(settings.MaxReceivedMessageSize)
            .At(addr)
    }));

其中IAdminService是的ServiceContract类。所有关于基于任务的操作MSDN文章引用导入服务引用时，设置一个基于任务的操作复选框。但在我目前使用的风格，也没有进口服务引用，因为我简单直接引用服务合同接口。

where IAdminService is the ServiceContract class. All the MSDN articles about task-based operations refer to setting a 'task based operations' tick box when importing the service reference. But in the style I am currently using, there is no imported service reference because I simple refer directly to the service contract interface.

所以我想知道怎样才能实现与改变目前的code量最少的基于任务的操作提供支持。

So I am wondering how I can enable support for task-based operations with the least amount of changes to the current code.

[顺便说一句 - WCFHelpers是产生BindEndpointModel和地址一个实用工具类设置为在此之前，code正在执行一个适当的端点地址]

[BTW - WCFHelpers is a utility class that generates a BindEndpointModel and addr is set up to an appropriate endpoint address prior to this code being executed]

推荐答案

该WCFFacility提供符合老异步模式的一些推广方法。这些可以很容易地转换成任务。

The WCFFacility provides some extension methods that conform to the old async pattern. These can easily be converted to Tasks.

尝试这些扩展方法：

public static class ClientExtensions
{
    public static async Task<TResult> CallAsync<TProxy, TResult>(this TProxy proxy, Func<TProxy, TResult> method)
    {
        return await Task.Factory.FromAsync(proxy.BeginWcfCall(method), ar => proxy.EndWcfCall<TResult>(ar));
    }

    public static async Task CallAsync<TProxy>(this TProxy proxy, Action<TProxy> method)
    {
        await Task.Factory.FromAsync(proxy.BeginWcfCall(method), ar => proxy.EndWcfCall(ar));
    }
}

在异步方法，他们可以被称为是这样的：

In an async method they can be called like this:

// Func<T>
var result = await client.CallAsync(p => p.SayThisNumber(42));

// Action
await client.CallAsync(p => p.DoSomething());
