Demos

The application showcases three demos:

Counter

Shows a button that updates a counter. This demonstrates basic logic in Blazor. This demo does not integrate with Orleans.

Fetch Data

A page that fetches read-only data from Orleans. The client-side app sources this data from the ASP.NET Core Web API running alongside Orleans.

A page that manages a todo list. Allows creating, editing and removing todo items.

The client-side app manages this data via REST calls to the ASP.NET Core Web API running alongside Orleans.
