How to add an explorer context menu for a file extension?

Question

I was inspired by my other question to try the following:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Classes\.sln]

[HKEY_CURRENT_USER\Software\Classes\.sln\shell]

[HKEY_CURRENT_USER\Software\Classes\.sln\shell\countlines]
@="countlines"

[HKEY_CURRENT_USER\Software\Classes\.sln\shell\countlines\command]
@="c:\\countlines\\countlines.exe" %1

This should be adding a context menu item named "countlines" that runs the "countlines.exe" command, but it doesn't work.

How does one add a context menu entry for a given file extension?

The default value of the .sln key should be something like VisualStudio.Launcher.sln. That's called the program ID (ProgID) and it's the key you should edit to change the context menu:

[HKEY_CURRENT_USER\Software\Classes\VisualStudio.Launcher.sln\shell]

A ProgID key always takes precedence, so any changes made to the extension key will be ignored when a ProgID is present. ProgIDs are mainly used to group extensions into logical file types.
