I notice the interactivity in Blazor Server works out of the box with no additional configuration when working in a local development environment.
It's my understanding that the interactivity depends on having a SignalR server. Is that correct? And if so, where is it configured?
I know there is documentation on how to setup a SignalR server in Azure and configure it in the application, but I'm just wondering how is it working out of the box when you have not done this?
