我的想法是，在VS.NET調試模式中運作這個“插件調試架構”（一個winForm應用程式），加載要調試的Addin Pair，然後，啟動“業務操作窗體”顯示出來，後續的互動将在兩個插件之間直接進行通信，而VS.NET提供了我們跟蹤到加載的插件的源碼中的能力，這樣就可以調試Addin Pair了。“插件調試架構”應用程式的主界面如下：
測試模式中的“異常（功能伺服器掉線）”用于模拟找不到對應服務端功能插件的情況。
我們知道，客戶插件（PassiveAddin）通過IServerAgent來發送請求擷取回複，在用戶端應用程式中，IServerAgent是對底層Tcp或Udp的封裝。在“插件調試架構”我們提供一個IServerAgent的實作給要調試的PassiveAddin使用，ESFramework給出的實作是AddinBridge類，它實作了IServerAgent接口，并且把PassiveAddin送出的請求直接送出給已加載的業務功能插件處理。AddinBridge實作如下：

有了AddinBridge的支援，“插件調試架構”的實作就非常容易了，我将上圖主界面中的按鈕點選事件源碼列在下面：
private AddinBridge serverAgent = new AddinBridge() ;
private IPassiveAddin passiveAddin = null ;
按鈕事件處理
1 private void button_server_Click(object sender, System.EventArgs e)
2 {
3 this.textBox_server.Text = FileHelper.GetFileToOpen("請選擇服務端插件" ,".dll") ;
4 IAddinManagement addinManager = new AddinManagement() ;
5 string msg = null ;
6 bool succeed = addinManager.LoadNewAddin(this.textBox_server.Text ,out msg) ;
7 if(!succeed || (addinManager.AddinList.Count == 0))
8 {
9 MessageBox.Show(msg + "請重新選擇插件！") ;
10 return ;
11 }
12
13 this.serverAgent.FunAddinManagement = addinManager ;
14 }
15
16 private void button_passive_Click(object sender, System.EventArgs e)
17 {
18 this.textBox_passive.Text = FileHelper.GetFileToOpen("請選擇用戶端插件" ,".dll") ;
19 IAddinManagement addinManager = new AddinManagement() ;
20 string msg = null ;
21 bool succeed = addinManager.LoadNewAddin(this.textBox_passive.Text ,out msg) ;
22 if(!succeed || (addinManager.AddinList.Count == 0))
23 {
24 MessageBox.Show(msg + "請重新選擇插件！") ;
25 return ;
26 }
27
28 this.passiveAddin = (IPassiveAddin)addinManager.AddinList[0] ;
29
30 this.button_bind.Enabled = true ;
31 }

44 {

47 else
48 {

50 }
51
52 //通過反射建立客戶業務操作窗體
53 Form addinForm = (Form)Activator.CreateInstance(this.passiveAddin.AddinFormType);
54 ((IPassiveAddinForm)addinForm).Initialize(this.serverAgent ,"000000");

64 this.passiveAddin = null ;

68 this.button_start.Enabled = false ;
69 this.button_bind.Enabled = false ;

你可以在54行代碼處添加斷點，然後就可以跟入兩個插件的源碼中調試了。
需要注意的是，為了VS.NET能順利的進入插件的源碼，在加載插件時，最好直接加載插件工程Debug目錄下的插件dll。
感謝關注！
