Daniel Sarmiento I have been coding 40 years. Once you become an expert at one (takes about 4 -5 years) you can pick up any language as expert in about 9 months to a year. if you do JQuery JavaScript you will find a lot of language constructs similar. The big thing will be learning frameworks and connection for dB. If you do database. Learn LINQ and understand Lambda. You will find it useful for a lot of data access regardless of data storage types.

Awesome! I'm hyped for Blazor WebAssembly. 😍

Exciting! I'll definitely be checking this out :)

The hype is real!! I liked python, but this alternative c# + frontend without js is impressive! Congratulations MS

Amazing The hype is real :D

Very very cool!

Developer tools don't display "file://" category. What could be the issue?

Please explain what you did @8:11 in the video, did you open the dev tools in the blazor app running on the browser, or open dev tools on another tab?

24:08 - not getting access to the OS YET. It needs to happen eventually. But obviously in a code signed way.

Athough Sockets are not supported in Webassembly, can I open Websockets inside C#?

Need more/better guidance around how to configure the browser and VS for debugging. I'm trying to get through the setup steps and it's not working as expected.

How to print report rdlc in blazor

Merging Blazor wasm component with Fluid framework is the future

Given that I have an existing project that is running ASP.NET Core 3.1 MVC with Razor views and sections of Angular served through Razor views.. How do I integrate Blazor Webassembly to such a project? Ideally I'd like to plug in some blazor webassembly SPA's for different sections of my project, but it's unlikely we are able to refactor the entire project at once. If I add a Blazor Webassembly project from the template, then I suddenly have two projects with each their own wwwroot.

I think u want to get rid of Angular and use Blazor Webassembly right? Even though its production ready. I wouldnt move yet. U can do a branch and test it out... but the performance is.... bad. Because they need to get rid of the Runtime layer which slows everything down.

Why no hot-reload how in react js?

This is bullshit. Webassembly is not to blame here. Because with Rust language u can have super fast performance on the front-end. Ok? Its because they need to run the C# Runtime on top of webassembly and then the bytecode compiled from C#. So you have another aditional layer which slows everything down. Please dont blame Webassembly... blame the runtime. When you use C++ or Rust it generates PURE webassembly without runtime. And its super fast. Blame this product. Not webassembly.

Herman Willems Please work on your comprehension and profane language. This is not a political site where you troll, it’s a site where professional programmers go. I am 100% for webassembly and want people to go with it. It executes fast, it’s a large load, especially with debug symbols it’s 11 mb release is 2mb. Angular is about 200k. I have been doing it since pre release back to November. I just finished my first professional project. I have found areas where it can use improvement over MVC. WASM really the first industry product that offers a system other than JS. It’s a great product and I want to see Microsoft keep working on it. I spent a year learning silverlight and they abandoned it. I don’t want to see this happen with Blazor.

It's oke that you dislike facts. Nice angular is 200k, but there are solutions out there that use webassembly without runtime. And literally have ZERO k overhead. With way faster runtime speed, because it doesn't have the .NET runtime overhead. I am not political in any sense. PURE technical. If you are really interested in the fastest solution for both back-end and front-end i point you towards Rust language, where they have back-end frameworks, and front-end frameworks which are in the top10 fastest front-end frameworks. If you program the front-end without framework it's close to the fastest possible to get with web-assembly.

@@charlesbaldo You really don't understand how this Blazor Webassembly works do you? It's a dirty hack. The .NET runtime is compiled with C++ to webassembly.

Not sure what was going on with him, but it doesn't take that long to load in reality. Maybe had to do with the debugger

So to run in the browser my browser must download the .net runtime in order to execute the IL. Do the modern browsers cache the runtime forever? I'm extreme interested in this technology but I am concerned about performance. C wasm can run very fast as can JS running directly in the browser however Ive seen some old benchmarks (pre release admittedly) and they were worryingly bad.. is this something that has been addressed or is likely to be?

But the server version offers everything the only difference is the hosting model. Personally I am excited about it and hope it makes it. It is MVVM, has excellent dependency injection for SPA It reminds me of the old webforms on steroids

His solution has three projects: (1) A .Net Standard Class Library Project (Employee, Departments, Gender) (see video 6) (2) A Blazor Server Project (see video 6) (3) A ASP.net REST API (see video 11) In video 6 Venkat avoids the Blazor Web Assembly project option because at the time it was in preview. Do you know if Venkat adds a WebAssembly project later in the series?

The horribly slow performance of this is wildly unimpressive to me.

Yeah i read also alot about the slow performance when u actually use alot of data..... its nice for a small todo app or hello world. Why they dont take blazor webassembly in the front end benchmarks? I think because they will be last..... something to do with the GC. the funny thing is. Rust Webassembly runs like at the top 10 fastest front end implementations. Thats probably because they dont need to worry about a GC or any "runtime" on top of webassembly.

We find blazor will take another year to get mature. If it will ever.

Blazor for me it wasn't secure , because you can steal code library from "xxx .com/_framework/blazor.boot.json" to download dll file , this made me very sad

WAY too slow

LET ME TELL YOU SOMETHING: Blazor has major performance problems because it needs to download the entire .DLL library in the browser. So, for now, all this WebAssembly Blazor talk is BS, it's only good for small websites, learn javascript ES6+, Blazor FOR NOW is not production-ready IMHO. P.S. Now, I want Blazor to succeed so maybe it's possible somehow to download some .DLL async, but I doubt it's possible and .DLL files are big.

Funny.. with Rust programming language we have front-end frameworks that also use webassembly but are actuallly extremely fast. Compiles rust straight to webassembly code. No runtime, No garbage collector. There is a reason why everybody programming Rust loves it. So instead of learning ES6+ invest time learning Rust. You can write Rust in the backend and front end at the same time. :) no need for javascript. Just Rust, HTML and CSS. Total access to all browser api's in Rust. And Rust performance on backend is on par with C and C++ and on the front end faster than angular,vuejs and ReactJS. Its literally a WIN-WIN scenario.
