✅ Why return IServiceCollection in an extension method?

Is there any reason why not to make the method void instead?

so it can be chained

of course 😄

some people really like to do

services
  .AddSomething()
  .AddSomethingElse()
  .AddAthirdThing();

services
  .AddSomething()
  .AddSomethingElse()
  .AddAthirdThing();

(I'm one of those people)

I never used chaining so didn't thought about that Yeah looks clean as well Thanks !

this is often called the "fluent" or "builder" pattern https://dzone.com/articles/fluent-builder-pattern

it does break when you end up with the ones that return a specialized builder, like AddAuthorization etc
