Fusion log viewer

你们在项目中是否是常常遇到DLL引用错误的状况，或者是DLL引用的版本，路径不对的状况。遇到这种状况通常处理起来比较困难，每每会以为DLL版本正确了，引用路径正确了，为何程序仍是引用的老版本，程序是从什么地方引的老版本呢？为何会引用到老版本呢？

今天我在项目中就遇到此种状况，屡次google终于找到了一个利器，他能够详尽的分析程序所引用的DLL，包括DLL的路径，版本等。

Fusion Log viewer:

此利器可查看windows服务，Asp.net及winform程序的Accemblly引用状况。

用法以下：

1. 打开 Fusion Log Viewer. 在开始菜单中的vs菜单下找以下所示的菜单项。

也能够在vs的控制面板上输入 fuslogvm 回车。

 

2. 设置log path,

注意，此路径必须是程序运行账号有读写权限。

若是是Asp.net程序，则须要将注册表项改为：

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion

下的key: ForceLog的值改为1.

3. 运行程序，点击刷新，便可看到各App加载的Dll.

注：asp.net程序要重启应用程序池。

4. 选中某项DLL,点击 “View log”,便可查看此DLL加载的详情。

5. 详情示例以下：
