A Simple C# Code

Hi, I need to add context menu in windows explorer , i am using sharpshell for this purpose. I have implemented the following code [login to view URL] I need further help to make it work , like when ever i do a right click on a text file , i should see the "Count Lines". I think this is related to registering the dlls like :: Unregister "C:\Windows\Microsoft.NET\Framework\v4.0.30319\[login to view URL]" "C:\xpst\[login to view URL]" /tlb:[login to view URL] /codebase /u :: Register "C:\Windows\Microsoft.NET\Framework\v4.0.30319 \[login to view URL]" "C:\xpst\[login to view URL]" /tlb:[login to view URL] /codebase Requirements : Please download the sample project , and write required code in C# , or some batch script to register all required dlls to make this work. I can pay only 5$ for this. Thanks
