Hi Devs,  I coded a Lightning Message Service channel in VS Code, deployed to Org, & then due to some issues later deleted it from the  Project AND Org.  But I think the LMS is STILL in the Org coz after cleaning up & deploying again it doesn't allow it and results in an error.

Here's my Q: do you know Where & How in Setup to: a) find Lightning Message Service channels, and b) completely delete them from the Org?

Thanks!!

Hey,

I will be finding this out for myself in the next little while, but meanwhile:  Does anybody know whether the following is possible?

Say we have a managed package, with NS prefix 'XXX' and the following class:

Is this legal?  Can you extend a virtual base class, if that class is sitting inside a managed package?  Can you even include virtual classes within a managed package, for that matter?
