Where are endpoints created?

Since the CreatePoints call is not done directly. I couldn’t find it quickly. I fiddled around. Therefore, for those who, like me, like to answer direct questions with simple answers, I inform you.

Endpoints list creation are started by Subscribe() in Microsoft.AspNetCore.Mvc.Routing. ControllerActionEndpointDataSource ctor. In the base class Subscribe passes UpdateEndpoints as action to ChangeToken.OnChange. The UpdateEndpoints() calls CreatePoints().

There is not enough information for one post, but it needs to be saved somewhere.
