BHO: where to write to regisitry?

Question

In C++, Browser Helper Objects should use IEGetWriteableHKCU to know where they can right to the registry. What is the equivalent function for C#? I want to save user preferences, it looks like the right way to do it on Windows it to use the registry.

The registry is rarely the right place to put user preferences. The user's Application Data folder is almost always preferred. — Joel Coehoorn, Feb 09 '12 at 17:38
I was looking for a "Best Practice" document from SM, but I couldn't find one. — Julien, Feb 10 '12 at 18:53
that's because the best practice is not to write to the registry for this. — Joel Coehoorn, Feb 10 '12 at 19:55

Seems to me it's just a function exported from IEFRAME.DLL :-

Therefore you can probably just use P/Invoke to call it, I might be a bit off on the signature here so anyone feel free to edit it:

[DllImport("ieframe.dll")]
public extern long IEGetWriteableHKCU(out IntPtr hKey);
