Support for net472 to allow vsix extensions to use the SDK

[POFerro]

Hi :),

I have a vsix extension to Visual Studio with a custom editor and would love to integrate my AI assistant ( developed with copilot sdk for .net ) into it, is it possible to make the SDK compatible with the same framework as Visual Studio ( net472 or net48 )?
This would be a nice feature to have.

Thanks in advance and best regards
POFerro
