Blazor

ISN'T SUPPORTED IN IE

What is it?

A framework that allows us to create interactive apps in c# what will be used, mainly, through a web browser

1. Takes adavantage of .net ecosystem for front end
2. Can use c# (linq and async programming)
3. Share code b/t front and back-end
4. Work w/ components

2 Hosting Models

Blazor Web Assembly

We use WebAssembly to execute .net apps in a web browser

2 options

1. Blazor (client-side)
2. Blazor hosted in .net core
   • Client-side + ASP.net Core

Does all the code go to the browser?

No, just front end code

Blazor Server-Side

1. Blazor app runs on server, and user interacts w/ it through SignalR connection
   • Doesn't need to download .net runtime
2. Advantage: Devices w/ less resources should be able to run the app w/o problems
3. Blazor server-side limitations relate to the server

Identity Server 4

Blazor WebAssembly has pre-configured Templates for IS4

1. Identity Server is a framework that uses OpenId Connect and OAuth 2.0
2. OAuth 2.0 is a standard authorization protocol
3. OpenId Connect has function
4. Centralizes authentication logic
5. Single-Sign On
6. External Identity Providers
