107. Should I Focus on Blazor or ASP.NET Core?

Should I learn Blazor in more depth or should I better understand ASP.NET Core? Which one is the better one to learn well first? Should I bounce back and forth or specialize in one? These are the questions we are going to answer in today's episode of Dev Questions.

Thank you, this does really answer the question though.

Hi @IAmTimCorey! You've recommended here to learn project types in this order : API, Blazor, Razor Pages, MVC. In your C# Mastercourse the order is quite different: Razor pages, MVC, API, Blazor. I am confused now.

[@IAmTimCorey]

The difference is how you are learning them. If you are learning them on your own and one at a time, that's the order to learn them in. The reason why is because you will get the most value out of your training in the quickest amount of time. If you only have time to learn one, you will learn the most valuable one (API). If you only have time to learn two, you will have learned the most valuable two (API and Blazor). With the C# Mastercourse, I designed it to give you a good overview of all of the major project types. Since we were covering all of them, I covered them in the order that was the most logical, where we could learn in a way that built upon what we had already learned.

I first time I have read about blazor in reddit then I give a try. I just felt in love. Before I used PHP and wrote few years ago filesharing website to upload my project files, screenshot whatever. But this was not nice to do in PHP. My portfolio website I tried in nodejs because I already tried few times nodejs as well. It was ok but it was tricky sometimes. I am also not pure Javascript fan. So when I tried blazor I had the SAME WOW effect when I tried C# for first time back over 10 years ago. Hehe. Now I am working with ASP core pure to see the differents. To be honest. With Blazor looks for me like a winner. The main different just, I know with php I just need to change the file to fix stuff. In nodejs almost same and restart the server. But with asp I need to compile. This means without my stuff I am not able to make quick fix.

Hi Tim, could you maybe sort videos in Beginner and Advanced category? I was watching this video until I realized that this is really for beginners but stayed till the end to keep the KZbin algorithm satisfied.

[@IAmTimCorey]

That's not really something that I can do. The reason why is because this is an advice video. It isn't on a specific learning path. For instance, you could have 20 years of experience in C#, but you might never have used ASP.NET Core. So, this video might be right for you, but you aren't a beginner. You could argue that it is for if you are a beginner in these technologies, but you might be an expert in ASP.NET Core MVC but you might never have used Blazor Server.

Both are equally secure because they are both server-side project types and they both are built upon ASP.NET Core.

[@bootsector13]

I think Blazor Server is not good in other countries where internet connection is poor. Pages loads delay and interaction to the UIs are not so responsive. Base on my experience.

[@johnsuckher3037]

does wasm have service workers? slow internet -> bad experience either way

[@bootsector13]

@@johnsuckher3037 Yes it does. You can also enable PWA on it

[@IAmTimCorey]

That's going to be tricky no matter what you choose. If you choose Blazor WASM, you will have a larger page load at the beginning, which might be disrupted or timeout because of connectivity issues. You will need to play around with different options and see what works best for your situation. Maybe Razor Pages is the best option for you. You don't get the client-side interactivity, but you get fast page loads, which means less possible disruptions. I would be interested in if you have tested Blazor side by side with other page types, though. You mentioned load delays and slow UI. That isn't a problem with Blazor. That's an issue with slow connectivity. A Blazor-specific issue would be if the SignalR connection was dropped and not re-connected. A slow page load means you are having trouble getting data from the server. That's going to happen no matter what web project type you choose. Even a PWA will have slowness in that case. In fact, it will actually be a bit slower than Blazor Server, since a PWA asks for JSON data, which is larger than the data transmitted over SignalR. The only difference is that the PWA can work offline, but that only matters if you are truly offline and not just slow.

[@holger_p]

By time your application is ready, maybe the internet connection has improved. Be optimistic. You put a rush on enforcing a faster internet, by building apps needing a faster internet. Users need to complain about the internet, in order to force phone companies or the gov. to improve it. Just be sure they don't complain about your app ;-)

MVC was always dreadful. Glad to see you are moving on.

Dear Tim, i build my project using blazor webassembly with API and it is functioning well, the only issue is that when i publish my blazor webassembly via godaddy it is taking around 15 sec to lunch but after that everything is fast, is this normal when publishing blazor webassembly and how can i decrease the loading time from 15 sec? Thank you

[@IAmTimCorey]

The first time any web server launches, it has to do a lot of work. That's why one of the tasks that you should do after deploying a website is test the site. That way, you are the one that experiences that slow load. After that, the server is up and running and is set to respond quickly.

[@youssefkassem9032]

@@IAmTimCorey Dear Tim my biggest issue is the start up page it is too slow but once the app has loaded it's generally super fast for general use (e.g. navigating between pages), is it because the performance in Blazor WASM has always been slow when compared to a JavaScript app

[@IAmTimCorey]

No, not unless you have a REALLY slow internet connection. For instance, just loading this videos web page (the one you are on right now) and playing just the intro of the video, you will load about 70MB. A Blazor WebAssembly project will be 2MB or less unless you have a massive application. It could be how you are trying to load the initial data (or how much data you are loading). Open up the developer tools in your browser and watch what data downloads and what is the blocking action. Also, remember that WebAssembly is JavaScript. Blazor WebAssembly just downloads a small (less than 2MB) dll file to be run by WebAssembly.

[@BigMTBrain]

@@youssefkassem9032 Hi, Youssef. IF your application is large, try breaking things down according to typical first usage, startup, etc., combine into separate assemblies, then mark all but those require for startup and priority functions for lazy loading per this MS doc: docs.microsoft.com/en-us/aspnet/core/blazor/webassembly-lazy-load-assemblies?view=aspnetcore-6.0

@@IAmTimCorey Too many. It creates a ridiculous learning curve and confusion as expressed by many.

[@IAmTimCorey]

That's not the nature of this industry. If you want simplicity, you are going to have to change careers and accept a much lower salary. If the software development industry took this advice, we would not have moved off of Basic. At the time, it was considered the ideal language. Anyone could develop in it and it opened the door for endless possibilities. The role of a software developer is to do the hard thing. That's really it. What that hard thing is moves as technology changes. It used to be that it was creating the hardware was the hard part (physical logic). Then we developed the ability to control machines with software. Hardware wasn't the hard part anymore. It was writing the software in complex languages such as assembly. Then we built abstraction languages. Then we made those abstraction languages easier and easier. This is where C# comes in. Then we built libraries to reduce the amount of work that needed to be done by the developer. With each improvement, the "hard part" changed. Now, the hard part is three-fold. First, you need to identify the best technology solutions to do your specific job. This is different for every job, so trying to pick one for everything is incorrect (and a failure to do the hard thing). The second part is to build out the logic properly. That means identifying edge cases, being mindful of security, optimizing for performance, building in resiliency, etc. The third and final part is to diagnose and fix issues, whether they be bugs in our code or changing circumstances around us. Yes, this means there is a large learning curve and yes, it is difficult to master these three things. But here is the thing - if it were easy, anybody could do it. If anybody could do it, businesses would not need to pay high rates to us to accomplish it. Imagine if our job truly could be done by anyone who could talk to an AI (it can't, by the way, because of the three things I mentioned). That would mean that companies could hire kids right out of high school to build software. In that case, what do you think they would pay them? Probably close to minimum wage. The harder the job is, the less people there will be that can do it well. The result is higher wages. The easier a job is to do, the more people there will be who can do it. The result will be lower wages.

[@RaZziaN1]

Better analogy would be: learn to drive this weird exotic car that might get big but it is not - or might go towards garbage dump (blazor) or learn to drive car and know how to drive any car (asp core)

[@johnsuckher3037]

ehh mvc, blazor/front-end frameworks, razor have different thoughts behind it. you learn asp net core by building with any of those... razor is the most beginner friendly if you don't start behind the scenes talk with backend with ajax... you can't learn to drive a car without sitting in one

[@IAmTimCorey]

That doesn't seem like a very good analogy. It seems like you are under the impression that in order to learn something, it needs to be "big" (I'm assuming that means that lots of companies are asking for developers in that subject). By that measure, your best bet would be to learn PHP. It's huge! It isn't the future, but there are hundreds of thousands of jobs for it. Blazor is relatively new, so you won't see it mentioned as much. However, it is the better choice for a lot of situations for new web development. That's what we are discussing here. Not what was chosen ten years ago by companies who are now looking for new employees. We are talking about what you should focus on when building a new application and for building up your new skills. You should learn all five web project types. You mentioned that you should learn ASP.NET Core. Did you know that both Blazors run on ASP.NET Core? No matter which one you learn first, you are learning the foundation for all of them. With your illustration, it sounds like you are looking at a toolbox and saying "Why should I have a screwdriver? I already have a hammer." and then throwing out the screwdriver.

Microsoft products is the Toyota Corola. If you want to learn coding, pick Java, Python or whatever.

Select a car (programming platform), with no need for using a specific garage is a much wiser decision.

[@amazur31]

what? why? theres no limits for .net / C#

[@IAmTimCorey]

I'm not sure you understand C#. For example, it seems like you are implying that C# is limited to Microsoft products. That is not true and hasn't been true for years. For instance, just with the templates provided by Microsoft, we can write applications for Windows, Mac, Linux, iOS, Android, the web, any cloud, Tizen, IoT, Xbox, and more. The biggest area where Microsoft templates don't take you is the Linux desktop. For that, you can use the free library Uno to do so. On the web, there are client-side applications, server-side applications, and even an application type that has the best of both worlds (something I'm not sure anyone else does - have a server-side app that also acts like a client-side app without being two different projects). With the same code, I can write an app for any platform, natively or with a wrapper (like Electron does). How exactly is C# limited? Oh, you also mentioned "price limits". I'm assuming you mean that everything isn't free. Visual Studio, the main IDE for C#, is free for everyone without limitations as long as your company makes less than $1 million per year. If you work for a company that does more than that, you have to pay, but only if you are doing company work. If you are doing personal work, that $1 million cap would be for your salary. That version is basically the same as the Professional edition. It isn't cut-rate or less than. It is what I use for both professional development and for all of my demos here on KZbin. That works both on Windows and Mac. If you don't like that, you can use VSCode (provided for free by Microsoft) on any platform (including the web). Just to round out this conversation, since it seems you might have not been tracking Microsoft for a while, here are some other things that Microsoft provides: * Private repos on GitHub - this is something Microsoft added when they bought GitHub and then expanded on. They also provide GitHub Actions for CI/CD in a limited capacity. * 12 Azure Services for life - for example, you can host 10 websites, 1 NoSQL database, tons of Azure Functions (up to 1 million calls per month), and a lot more for free plus for the first year, you get even more for free. * Private repos on Azure DevOps with free CI/CD, Boards (issues, Kanban, etc.), package hosting (private hosting, plus replication for NPM, NuGet, and more), and lots more * Open-Source contributions - all of .NET Core, VSCode, major contributions in git, and a lot more To summarize, you can create commercial apps, host them on GitHub, have an automated build and deploy process, and you can deploy your app to any platform in the world all for free. So let me ask you - do you still have the same opinion? If so, why?
