如何编写Web服务：处理外部事件 [英] How to write web service : To handle external events

问题描述

我开发了UCMA控制台应用程序。它向多个用户发送IM。

现在假设发生了一些外部事件，然后我的ucma应用程序应该向用户发送IM。我有sahrepoint网站 外部事件可能是数据库中的任何更改。 

所以我的要求是我需要在UCMA应用程序之上开发Web服务。

<我完全是新手。

在网上我发现创建网络服务。在Web服务中编写实现。创建控制台应用程序并在其中添加Web服务的引用。我指的是以下链接

我的UCMA代码如下

 

使用系统;

使用System.Collections.Generic;

使用System.Linq;

使用System.Text;

使用System.Configuration;

使用System.Security.Principal;

使用System.Security.Cryptography.X509Certificates;

使用System.Net;

使用System.Threading;

使用System.Diagnostics;

使用Microsoft.Rtc.Collaboration;

使用Microsoft.Rtc.Signaling;

使用System.Runtime。 InteropServices;

您是否查看过UCMA 3.0 SDK附带的Contact Center参考应用程序？

I have developed UCMA console application . It sends IM to multiple users .

Now Suppose Some external event happen then my ucma application should send IM to users . I have sahrepoint site External event may be any changes in database . 

So My requirment is I need to develop web service above UCMA application.

I am totally new to this.

On net I found that Create web service . Write implementation in web service . create console application and add reference of web service in that .I am referring following link
