So far JavaScript had a monopoly on web code - we could either write some form of JavaScript or not execute code on the web. The WebAssembly standard changes that, by defining a binary code standard that could be directly executed by the browser. That binary code could be written in any language compilable to wasm - and that could mean C# as well. In this session we'll take a look at Blazor, an engine that enables us to write C# code for the server, C# code for the client, run it, and, if we're lucky, it might even work.

WASM using Blazor

4. Building a web-application

5. Regular Web Application
We have to use a client and a server architecture
@swekster
We'll write the server in C# (many other options available, including JavaScript)
We have to write the client in JavaScript

6. Why JavaScript Sucks
Built as a scripting language – and the legacy shows
@swekster
No language solutions to common programming problems (i.e. namespaces)
Weird type coercion and equality rules
Half-baked object orientation
It's gotten much, much better in recent years
Still, sometimes feels like putting lipstick on a pig

7. And now for something completely
different...
Let's build the server in JavaScript (because we want to)
@swekster
Let's build the client in C# (because we now can :D )

8. Our first C# web-client

9. What did we see?
C# running in the browser !!!
.net dlls executing on the client !!!
MASS HYSTERIA !!!
@swekster

10. What did we see?
@swekster
C# running on top of the mono runtime, build on top of wasm
Razor-like syntax
Still highly experimental, but showing tremendous promise

11. So, what can Blazor do?
@swekster
A component model for building composable UI
Routing
Dependency injection
JavaScript interop
Usage of existing code libraries

12. C# all the things!

13. Bottom Line
@swekster
Not ready for production (yet)
You can help with development
Gives us a real alternative for modern web development
