With the idea having been approved by Lunar over on Discord, it's time to discuss details.

The full concept can be found here. To summarize:

• This aims to be a base framework both CNext and SlashCommands can leverage for their purposes, unifying a lot of logic in one codebase. It aims to provide performance improvements and additional functionality alike.
• This does NOT aim to unify CNext and SlashCommands into one single library. As unfortunate as it is, the separation and its side effect (such as duplicated attributes) will remain.
• This does not aim, but will not reject the notion to permit one method be used for both a regular text command and an application command.
• This does not aim to break backwards compatibility in any capacity, save the following: the .NET 7 AOT form factor might be dropped/receive limited support. Comments/Discussion requested.
• BCF aims to be usable without ever exposing it to the end user, however, it should be possible for the end user to leverage additional power by referencing BCF directly.

Furthermore, SlashCommands and CNext will receive new surface areas to make use of the new capabilities of this framework.

Approximately here you will find the API surface draft, reflecting the current state of discussion: https://gist.github.com/ExaInsanity/34109387507cdcc636b386650b738458 (so far only including one namespace)

Other topics to be discussed: extendibility, .NET 7 AOT, additional compilation targets (see the first link)
