Blazor, a new framework for browser-based .NET apps- Steve Sanderson

[@sifiso5055]

This is one of the most high quality talks I've ever seen

[@geertdepuydt2683]

some seriously impressive presentation/sales talk. completely sold, and i'm only 20min in, lol

[@SimpMcSimpy]

I just hope MS don't abandon this project sometime in near future because this is freaking awesome. Yes, there are still some problems to solve but better that then going forward with all that JS nonsense.

[@kenbee85]

Agree...

[@flygonfiasco9751]

Realistically, JavaScript isn’t going anywhere anytime soon. There’s huge strides to make in webassembly still. Not to mention the sheer amount of maintenance for systems using JavaScript.

This is a productivity game changer. This would have compressed my last 20 years into 5.

[@TonyHenrique]

This .NET WebAssembly AOT is awesome.

[@yeetfarmer]

When I created a project using the blazor hosted template, the server project did not contain the Index.cshtml page. It was used in the example for setting up the asynchronous call to get the page to load immediately. Does anyone know how to set this up? Edit: Time code is 48:10

[@finch9668]

I have the same question.

[@ArgeKumadan]

some1 should highlight this

[@arwahsapi]

There has been updates in Blazor templates for VS. The .razor extension might have replaced the .cshtml

[@ljupconewman9357]

I love the idea about not using Javascript. This is the right step towards dethroning it.

[@pspicer777]

Ahh the optimism of youth. For myself I am thinking the only way forward is to use COBOL in the browser!! Then we will have something that unifies all. 😂

[@ljupconewman9357]

@@pspicer777 that's a great idea! 😂

[@JohnWick-rc9qq]

Why not just learn JS, which is an incredible programming language?

[@ljupconewman9357]

@@JohnWick-rc9qq when there's an ide like visual studio I'll use it. Otherwise my JS code often doesn't execute and I don't know how to pinpoint the problem since there is hardly or isn't any indication what went wrong. Correct me if I'm wrong and if such tool already exists.

[@JohnWick-rc9qq]

@@ljupconewman9357 VS Code, Webstorm, Sublime Text, Atom, etc. A ton of great IDE's out there. Good linting and coding practices make JS as easy to debug as any other language. If you write crappy JS, like any other language, it's going to be hard to find the problems. If you're struggling to figure out problems, it's not the language or the IDE. ;)

[@darkclove7365]

It's been a while since I was excited like this.

[@WeBhartiya]

Great explanation , energetic presentation

[@fernandofarofa]

I decided to do anything else for the web until this comes out.

[@arwahsapi]

...and may I know what else did you decide to do for the web until this comes out?

[@andystannard]

This looks awesome, I was wondering about this tech and the electron wrapper for creating desktop apps with. Does this mean you could use with a PhoneGap wrapper for mobile too or is the web assembly off limits with that?

[@wudewang9947]

Vary awesome, worth to learn more about this!!

Page renders in 26ms. Very fast, but every programmer who is also an online gamer is like "26ms? omg, I'd be dead."

D/L and cache until the next update. Most users / enterprises have access to broadband. We don't live in dial-up only world anymore.

[@dizhar8888]

Is this production ready?

[@dmitriyobidin6049]

from docs: Blazor is the experimental client-side hosting model of Razor Components. General rule, if it doesn't have stable 1.0 version it is not ready for prod.

[@mariacobretti]

Im not a web developer cause I find JavaScript to be fu.kn disgusting and so never really bothered to learn it. WebAssembly however looks amazing and it seems like I made the ride move skipping on js

[@BinaryReader]

I don't like the template logic so much, it looks pretty unwieldy. Is there a better alternative than Razors cshtml?

[@tallgeese1]

Be sure to share your concern on GitHub.

[@iancarr3923]

I like this as well. However, I have tried to set up a template as demonstrated in the video (Templates and Generics section) but cannot get it to work. It builds ok but hangs when trying to load. I just get "Loading... ".

[@iancarr3923]

Fixed. Incorrect tag syntax - using closing tag.

[@meirkr]

Is it possible sharing the sample code?

[@KoMaHu3aM]

I think that's the blazor template which is coming with .net core preview 3 something. Check that out.

[@meirkr]

@@KoMaHu3aM I'm asking about all the additions presented, like the special demo list..

[@InayetHadi]

I thought Razor Components was going to replace Blazor with Net Core 3.0 . He should be doing a talk on Razor Components since that is going to work with Net Core 3.0

[@MikeSheen1972]

Blazor server side was renamed Razor Components and Blazor client side was kept as an experimental project, but 2 days ago they decided to rename Razor Components back to Blazor to prevent confusion.

[@Ian-yi7ks]

@@MikeSheen1972 Well ive seen the introduction video to razor components and the project structure within VS isnt the same as the one in Blazor. You mentioned thought Component got renamed back to Blazor server side. I do not have the template Razor Components in my vs preview, which speaks for your statement, but the created project from the Blazor server side template has the same structure like in this video. Which is the structure of the client side. Im really confused by now.

[@not_AI_bot]

how about performance? I googled there were a big performance issue

[@maacpiash]

Watched this video before.

[@MeghRoy]

Please please please don't suck and please don't die. We need this. I need this. Enough of this JS nonsense.

[@Cristian-ek7xy]

Gosh, I just saw 20 MB for a TODO list, that's insane

[@chriscardoz]

I'm not really sure this might work. Based on my experience, every team has a different UI team that not only specializes in responsive UI but also contributes to UI design for better user experience. Also, there's a large pool of devs who know html, JavaScript, css and it would be cost efficient and easy to find replacements rather than look for devs that work on blazor. If this technology picks pace in the next year, it might survive 3 or 5 years. I feel this project is most likely to die like silverlight.

[@vinzer72frie]

This framework is not intended towards new developers rather it aims for the already senior net developers, you say budget efficiency of hiring cheap frontend developers well if a company uses net they will certainly not hire "html javascript" designers. Silverlight failed because it required plugin installations blazor does not

[@haleaurelian]

A W W W E S O M E ! ! ! Goodbye desktop apps..

[@MartinHAndersen]

This is fuc**ng awesome. A new Silverlight?

[@pushqrdx]

no, it isn't silverlight, it doesn't need a plugin or anything else to run in the browser. It just runs and supported out of the box in most browsers.

[@MartinHAndersen]

@@pushqrdx Thanks I know how it works. But will anybody use it?.

[@scottpeal60]

@@MartinHAndersen I am using it

[@ManuelBasiri]

@@MartinHAndersen I'll be waiting for an stable version and will replace my entire frontend logic with this lovely alternative. When the syntax become second nature, this will massively streamline the entire development process. At least in my project that's how I see it and I'm sure other developers will feel more comfortable when use it more.

[@MartinHAndersen]

@@ManuelBasiri I have been a .NET developer since version 1. I once persuaded my fellow programmers to move a very large application to silverlight to web enable it. Silverlight was a good technology but died and I felt bad. I have more hope for Blazor. it's build on standard technologies and you get to use C# that's awesome. But again Angular, React and Vue has come a long way. And we need to move many of the feature from this frameworks to Blazor. e.g. tree shaking to reduce the size of web assemblies. Today it's also easier to get a front-end developer that master Angular than a C# / Blazor developer because its new but I think that Blazor will always be a niche product.

[@rogeriorlima3]

Beware Microsoft will discontinue Blazor in no time, or bet on it. Remember Silverlight ? Remember MTS ? Microsoft never respected developers, remember what they did to companies that invested millions in Asp.Net and VB.Net? so ... beware. Today she says it's a wonder, tomorrow she says it's no good. When you write code the technology you used should never be discontinued. Software is an asset that should never expire. But Microsoft ($$$$$$) always needs to create something new and stop what is working.

[@aliayhan8883]

WebAssembly/Bytecode can do what javascript can do! not really! Good idea but javascript will be always better options. I think Microsoft just want to eliminate post/back :) Also i saw 43 requests 18.33 mb what browser doing, ouch!

2 MB for the mono wasm + all DLLs ? I am sorry but that is a no go for me. My last enterprise project's bundle was 200 KB. At this moment, this technology does not make a sense for me.
