Sitecore Best Practices (V10.1) 002 - When start a new feature don't include the .sln file and try to setup a VSIX (extension template)

 This is very very basic but just wanted to cover here, when we start a new feature don't involve the .sln (Solution) project as we have the main solution for the project.

I would sugget to create a new VSIX (extension template)
