Fusion log viewer
大家在项目中是不是经常遇到DLL引用错误的情况，或者是DLL引用的版本，路径不对的情况。遇到这种情况一般处理起来比较困难，往往会觉得DLL版本正确了，引用路径正确了，为什么程序还是引用的老版本，程序是从什么地方引的老版本呢？为什么会引用到老版本呢？
今天我在项目中就遇到此种情况，多次google终于找到了一个利器，他可以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引用情况。
用法如下：
1. 打开 Fusion Log Viewer. 在开始菜单中的vs菜单下找如下所示的菜单项。
也可以在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帐号有读写权限。
如果是Asp.net程序，则需要将注册表项改成：
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion
下的key: ForceLog的值改成1.
3. 运行程序，点击刷新，即可看到各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”,即可查看此DLL加载的详情。
5. 详情示例如下：
