C# asp.net web引用调用超时

具有本地控制台托管的WCF服务。在dll项目的web引用中添加了相同的内容。在我的asp.net页面中使用

代码：

当尝试从网页拨打电话时，它超时。当我从另一个WCF服务中使用相同的服务并拨打电话时，它工作正常

注:

---

我使用的asp.net版本是2.0.50727，因为它是一个客户端代码，我无法升级它，所以我使用了asp.net 2.0.50727的web引用。

增加超时时会发生什么情况？尝试过，但也失败了。托管WCF服务中没有太多进程，它将返回数据契约。注意：当尝试使用另一个WCF客户端代理时，它正在工作。

 PrepaidManagementService proxy = null;

        try
        {

            proxy = new PrepaidManagementService();

            res = proxy.balanceUsageSummary(balanceUsageSummaryRequestDtoObj); // Timeout happening here.
        }
        catch (TimeoutException e)
        {
            res.returnMessage = e.Message;
            proxy.Abort();
        }
        catch (Exception e)
        {
            res.returnMessage = e.Message;
            proxy.Abort();
            throw;
