IShellExtInit Initialize isn't called when right-clicking on a single file

Question

Hello, I'm trying to write an explorer shell extension that inserts a context menu item when the user right-clicks on a single file. I have implemented IShellExtInit Initialize, but it is only invoked when the user right-clicks on a folder, not a file. Is there something special I have to do to get this function invoked for a single file?

Thanks

Apparently the consensus is that shell extensions shouldn't be written in managed code:

However, implementation in C/C++ isn't an option in my case. What I'm trying to do is provide a menu item on the Windows Explorer context menu that launches a specific executable whenever a single file of any type is right-clicked. Can someone can suggest an alternative way to achieve this?

Thanks
