Yes Blazor Hybrid and Blazor Native UI should both be done. This is what I wanted to do long ago in the early 90s. Please deliver both of these technologies. This was the point of Canvas Control Library that I invented in 2012. Really what should be done is the Web Browser needs to be refined as the container to just draw on. What is the HTML element? It is just a screen a 2d place to draw whatever you want. This implies that the Web Browser is a 2D screen again to draw whatever you want. What is a Window Manager, Windows and Controls? It is just to manage and enable drawing on the desktop GUI of an Operating System. Which means cut through all the layers of abstraction/indirection and do what I showed open-source of this in Canvas Control Library into the basic Web Browser. Change the Web Browser to do what Canvas Control Library does in Javascript. An OS GUI inside of Window on the OS's GUI is what I mean. Yes, Terminal Server (remote GUI desktop) already does this but add to it all the functionality of a Window Manager, Windows, Controls, etc. This is what I thought of in the early 90s when I saw Mosaic in the GMI (Kettering University) UNIX lab. This should have been done back then except that the average person's computer and bandwidth (yes 56k modems) did not support it back then.

Blazor can't replace JavaScript functionality on the web currently, we have invested thousands of hours and dollars to master JavaScript , and the supporting frameworks, like Vue, React, Angular. Also most of the web applications are using some JavaScript framework. I think Blazor is a premature for usage in the current time as it is highly server depended (as server application) which makes it slow compared to HTTP protocols or Ajax, and heavy on using browser caching in case of using web-sockets.

Looks like a competitive for Flutter.

Please release all of them, I am really interested in Blazor Hybrid and B. + Native UI. In Blazor Hybrid it would be extremely cool if you easily could build a cross platform App running on *GNU/Linux* , Windows, Android(, iOS & Mac). Same for new Blazor + Native, but also please for Xamarin Forms + MvvmCross, GNU/Linux | e.g. GTK just is nearly always missing, it would be so cool if you would have a few options for doing all cross platform with .NET with a few clicks. Then C# and .NET would be one platform for nearly everything. My best dream would be the e.g. following: Open Visual Studio, create Blazor Cross-Platform project, configure UI framework to e.g. WebAssebly, or Native-UI or a mix, configure wanted platforms, like *Linux* , Windows, Android and so on, get a nice template like currently the Blazor template, maybe some more advanced examples in there to show more of what this is capable of or for easy editing, chose platform to start like Android simulator or e.g. Gnome 3 from WSL2 or just Windows, click run and it should work. :D ♥️ This would be soo cool. 👌😎 But it is already impressive work, good job. 👍

You don't have to use CSS directly though, if you don't want to. There are tool-kits such as BlazorStrap that allow you to use bootstrap CSS in your blazor project without ever touching a character off CSS code, you just use custom tags and attributes to style your UI. The idea behind blazor is component composition, so while you may have to use some CSS initially, the idea is that you will build up useful UI libraries that you can reuse, in much the same way you build up libraries of code you reuse. Once you've built something and actually added the CSS inside your component, you can then easily attach attributes to that CSS code so you never have to touch it again, and instead just let C# do the work. It's all rather wonderful really :-)

browser based .net. :D

What is .net? Is it a JS framework?

Here's to the codes and slides, in case you're too lazy: aka.ms/sanderson-london-2020

It would be cool if you could provide a boilerplate as a state of the art with working with Blazor. .NET Developers are the type that want to know how things should be done. They are not passionate about the flexibility of the technology. That type of "artists" are in the javascript world. They are the ones who like to develop technologies, to complicate things and get nothing done. .NET Developers just want to create projects that are using the .NET Technologies. We like to hear "you should do it like this" and not "you can use it with Webassembly or with SignalR, it's up to you". It shouldn't be up to me. If switching to Blazor means I need to invest 1-2-3 weeks to make reverse engineering, to test if qRPC is a good idea or not, if to choose Webassembly or SignalR, to fix tons of configuration problems, then I rather stick with something I know already: React, Angular etc. Because I have already been through the headaches of choosing what is the best way of working with it, of configuring it, and so on.There is too much flexibility and negotiations on how things should be done. We don't need flexibility, we just need technologies to create the products we want to create. What if we would negotiate how programming languages work? You would get problems like: - changing to a different company/projects means learning the new programming language; - after using the language for 1 month, you realize your language cannot be generic, so you change everything. You refactor. After 3 monts you realize that it has some other dysfunctionalities because of the configurations you have chosen. Refactor...And that is exactly what is happening when technologies are being negotiated. We don't create low-level technologies, we just work with it. We don't want to do the research if qRPC is better than JSON or not. Just tell us which to pick.At this moment almost nobody is using Blazor because nothing is clear. Only the mongoDb-hippies are playing with it. But no serious company is attempting to use Blazor in a serious project that they want to create. And I think this is sad, because Blazor should be a real breakthrough. Please, just clarify the things. Make the default boilerplate. Set the rules. And let's get this going. Btw, a really nice presentation. Steve Sanderson is a really cool guy.

Oh man ... another technology which will last how long? Reinventing the wheel over and over again!

So unfortunate that any time was spent on server side and not just devoted all the Blazor dev time to client side. Everyone wants client side.

Kudos for using WA, an open standard. Yay... But do you really need to create another web component standard? Seems to be like you would be in much greater gain if you could use native web components and give developers access to already made components and perhaps an open component directory, and the ability to share and improve. Or is Microsoft still anti-open-source and open standards?

For those of you that hate C# or your company won’t jump on the Microsoft bandwagon, Nest.js is a great new backend framework that’s easy to work with and provides a lot of functionality like data validation and transforming to solve a lot of the problems that Blazor server attempts to solve. It looks and works a lot like angular, uses Typescript, and also supports gRPC along with many other microservices, runs in Node, and is 100% free and open source.

I think Microsoft is the most confused company in the world, I don't know the teams inside it work together or against each others. Blazor here can works native on mobile devices at the same time there is Xamarin you can make native mobile application with it , you want make server side application to make apis for your web/mobile/desktop apps you can do that with Blazor at the same time there is ASP.NET Core !!! I think Microsoft they must work on one Framework that works on all devices on any OS Like Google's Flutter (In Flutter you can make mobile/web application with it and very soon it will support desktop Windows,Linux and Mac OS and they plan to works on Chrome OS and Fushia OS the future OS from Google)
