Too bad MSFT took 20 years to figure this out. Once they killed Silverlight (because Apple wouldn't allow browser plugins), it sent a huge negative message to those loyal to them.
Later confirmation of ridiculous descisions they made: 1. They fractured their own desktop environment with UWP. 2. Abandoning WPF while denying it. 3. WPF never was fully able to embed their own browsers. 4. Their ridiculous IE and Edge browsers.
In the meantime, NPM, Node, Electron, Angular, React, Vue and Chrome captured the frontend along with huge open source contributions.
Jumping on the Blazor bandwagon, to me, is regressive. How many Blazor jobs are there on LinkedIn?
MSFT throws their developers under the bus too often and are untrustworthy in that regard.
While I'm also less than enthusiastic, I would counter that MS open source has been very good overall. Silverlight was never floss. .Net Core has seen some really great strides and it's a decent option.
I still prefer node and react, and for web assembly find rust+yes more compelling. I wouldn't about C# as an option on the backed, I just don't like Blazor.
When I speak about C# open source being dead, I'm comparing it to NPM. NPM alone is a million times more robust. Right now, Blazor open source contributions are laughable. I don't feel that will change much. MSFT has been sleeping while they built Azure. They are 10 years too late.
I'm junior, but reading the article I thought great for C# guys, I mean welcome to the web, but maybe I'm ignorant on this assuming that we basically have this with JS/TypeScript? Why move off that ecosystem that's only exploding with more opportunities to something that's catching up. With all that's going on in JS I'm just not sure there would be a problem Blazor solves that's not already solved... Am I wrong? I am just speculating on this latter point, so please share your wisdom Dev crowd. :)
We'll know the goodness of blazor once the jobs show up. Today they're not around.
But yes, I agree with you, why Blazor? We already have it all.
For me blazor for the web it's like Xamarin for mobile, I'm an old MS developer, and I can create a functional app in 2 days after starting with blazor. I don't know how much time would take to do the same if I start with angular.
Yes both React and Angular have ramp up time but the data binding concepts you know from Razor are the same.
You'll have no problem learning React and Angular. The need for React and Angular people exceeds supply which is good.
We'll see and prove it by job openings and salaries.
Yes Typescript is MSFT, in particular, Anders Helsberg, the C# architect. His work has always been excellent.
I replied to a comment of yours on another article but since you probably haven't seen it, I'll reproduce it here.
Your original comment:
Latest TechEmpower results as of the time of posting this:
As you can see, Node.js is so far behind ASP.NET Core in all tests, it's not even a contest any more.
As for front-end C#, here's an example: n-stefan.github.io/diabloblazor
It is a port of this: d07riv.github.io/diabloweb
Being static it doesn't use a server at all, but server side prerendering (initial rendering) is baked into Blazor and can be used with sites that are hosted by an ASP.NET Core server. There's also server side Blazor, which doesn't need WebAssembly and still behaves like a SPA/PWA - no full page reloads, uses differential rendering, etc.
Edit: added further benchmarks
.NET Core/C# wins 10/10 tests vs OpenJDK/Java:
It should be noted that both the TechEmpower tests and these benchmarks were run on Linux. On Windows .NET Core/C# would likely be even faster."
Will Blazor make it? Perhaps but there are no jobs.
Will they rewrite VS Code in C# WASM? Never, Electron and Typescript work beautifully for millions of developers daily.
Chrome, the browser that won, will remain a Javascrpt friendly stack.
Of course there are not many jobs YET, server-side Blazor launched with .NET Core 3.0 only this September, while client-side Blazor is still in preview and will launch in May 2020, if all goes according to plan.
It is possible to host Blazor on Electron for desktop apps:
However, they haven't stopped there:
It does away with Chromium and Node for significant download size and memory footprint savings.
The newer IEs were arguably much better than older ones, while Edge was better still and now there is Chromium based Edge, so nothing left to complain about.
One of the main selling points of Node was a relative speed advantage: no longer true. Another was enabling same language development across front- and backend while others didn't: also, no longer true.
Hell, Python is most popular now and it's a slow, niche language, only ideal for ML/AI. Already for webapps there are many alternatives that are far better and for game development you can forget about it.
Oh yes, some people hate and will hate MSFT no matter what, and that has nothing to do with the quality of .NET Core/Blazor.
Those benchmarks look very wrong. There is no way node is 8 times slower than ASP.NET on the same hardware.
Most likely they ran one instance of node on an 8 core machine. Node runs on a single core, while ASP.NET takes advantage of all cores.
You need to configure node as you would in production, using something like PM2 or StrongLoop Process Manager with an NGINX load balancer in front. This allows you to run 8 instances of node so that all 8 cores are used.
The results in this configuration will be very different.
Please tell us more on how node utilizes all cores. An article perhaps? I confess my lack of knowledge on getting Node to run on all cores.
Process managers like PM2 and Strongloop PM start multiple instances of your app, each of which runs a single thread. By default, they start a number of instances equal to the number of CPU cores.
If any of the instances crash, the process manager will restart them.
You can run an NGINX instance as well to load balance between multiple instances running on a single machine or across multiple machines as well. This is only needed in production. You can run your dev instance with just PM2 or Strongloop directly if you need to test performance. You usually only need to run one instance for most dev work though, which means you can just run node directly.
There is also the node "cluster" module, which you can use directly in your node server code to run multiple instances of your app. I haven't used this recently, but there were some performance issues with it before. Not sure if this has been improved.
Node also supports manually firing up threads for whatever purpose you may have. This is often used to create worker threads for any long-running CPU-intensive tasks. The main node thread and the worker thread can communicate, if necessary, using IPC.
It is very important in node to avoid blocking the main thread since no other requests can be handled in that node instance until the work is complete. Worker threads are a good option here.
They are not wrong.
Server config: 14 physical cores, 28 logical cores (HT), 32 GB RAM.
The Node.js plaintext code is running as a cluster of 28 processes.
So yes, ASP.NET Core really is that much faster, time to wake up.
Excellent information Ken. Looks like I have some major 2020 studying to do.
Thanks for the links @n-stefan. Good to know they are using clustering.
I still think something is not optimally configured in the node case though. I could believe a 2-3 times improvement, but 8 times still makes me very suspicious. Benchmark results are notorious for being sketchy or having one configuration optimal and another sub-optimal.
It would be interesting to see the number of requests that each node instance handled to make sure the distribution is fair. The fact that there were 89 errors makes me think that perhaps the distribution was not even, and so some requests errored out.
It would also be interesting to set cluster.schedulingPolicy = cluster.SCHED_RR; mode to see if that helps.
cluster.schedulingPolicy = cluster.SCHED_RR;
A comparison against PM2 or StrongLoop would also be good to see (might try this out if I have some time in the next few weeks).
The difference is smaller in the 5 other tests.
You could open a PR, if it's good, they will probably accept it. I'm also interested in having Node.js (and all others for that matter) run at its (their) true potential, unhindered by bad configuration and the like.
