Fusion log viewer

你們在項目中是否是常常遇到DLL引用錯誤的狀況，或者是DLL引用的版本，路徑不對的狀況。遇到這種狀況通常處理起來比較困難，每每會以爲DLL版本正確了，引用路徑正確了，爲何程序仍是引用的老版本，程序是從什麼地方引的老版本呢？爲何會引用到老版本呢？

今天我在項目中就遇到此種狀況，屢次google終於找到了一個利器，他能夠詳盡的分析程序所引用的DLL，包括DLL的路徑，版本等。

Fusion Log viewer:

此利器可查看windows服務，Asp.net及winform程序的Accemblly引用狀況。

用法以下：

1. 打開 Fusion Log Viewer. 在開始菜單中的vs菜單下找以下所示的菜單項。

也能夠在vs的控制面板上輸入 fuslogvm 回車。

 

2. 設置log path,

注意，此路徑必須是程序運行賬號有讀寫權限。

若是是Asp.net程序，則須要將註冊表項改爲：

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion

下的key: ForceLog的值改爲1.

3. 運行程序，點擊刷新，便可看到各App加載的Dll.

注：asp.net程序要重啓應用程序池。

4. 選中某項DLL,點擊 「View log」,便可查看此DLL加載的詳情。

5. 詳情示例以下：
