Where does Microsoft Edge Dev Channel check for NativeMessagingHosts on Windows 10?

Question

I tried adding the registry key on HKEY_CURRENT_USER\Sotware\Microsoft\Edge Dev\NativeMessagingHosts\com.myapp.id but when I try to connect to it, from my extension, I get this error

Specified native messaging host not found.

I already checked my manifest and it's properly pointing at the executable (with escaped \ in the path) I also tried omitting the full path as the Microsoft documentation states that on Windows, I can use relative paths but no success there either.

This leads me to believe that maybe Edge is looking at a dfferent registry key but I don't know where.

To be clear, I am talking about the new Chromium-based Microsoft Edge, and not the older one that was restricted to UWP native messaging hosts.

Answer 1

I solved it. Apparently, Microsoft's documentation is wrong. It's still looking for the registry key in HKEY_CURRENT_USER\Software\Google\Chrome\NativeMessagingHosts even with the official stable release.
