Top Online Courses to Make You a Master Blazor Developer

The power of Blazor is apparent, since it allows you to use Visual Studio and C# to make web applications that run with speed near native hardware level performance.  However, even seasoned C# and veterans need to learn about the workflow and underlying architecture that powers Blazor.  This means both newbies and experts in web development will need to educate themselves on how to properly create Blazor applications. To that end, in today’s article I am going to review and outline the best Blazor online courses.

Before we jump into the best Blazor courses, lets start with an overview of how it works, starting with its roots in WebAssembly.   Blazor uses open web standards to bring the power of Mono and C# to all modern phone and desktop browsers.  This gives you the power to write C# code that powers the client and server-side, replacing JavaScript and providing fast execution of your code for maximum performance.


What is WebAssembly & Why It Changes Everything

Blazor wouldn’t exist if it weren’t for WebAssembly.  WebAssembly is an open standard that was developed by the W3C, Mozilla, Microsoft, Google and Apple, and is a part of the WWW standard as the 4th universally supported browser language, joining CSS, JavaScript, and HTML.  The purpose of WebAssembly is to provide an executable format for transferring binary programs to leverage near full performance on the client machines.


Wherein JavaScript is interpreted in real-time by the client browser and then executed, WebAssembly is pre-compiled byte-code that is meant to be executed directly by the browser.  That means you will never write a line of WebAssembly directly, but instead use other languages and then compile it to WebAssembly.


This is a big deal because it enables new web applications to be as performant as desktop applications, while also allowing developers to use the familiarity and power of Visual Studio and the C# language.


What is Blazor & How it Makes High Performance Web Apps Easy to Create

To put in simply: Blazor allows you to use C# to create WebAssembly powered applications.  But how does it do that?  Well, to begin with Microsoft ported Mono to WebAssembly, meaning you can now use it to run any .NET library natively through a web browser!


Exploring the Best Blazor Courses Online

One of the best parts about Blazor is that it is both a great entry point into C# for new developers, but also an easy way for existing .NET developers to extend their existing skills into the world of hardware accelerated web development.  However, because some people have pre-existing experience in C# while others may be new to it altogether, I am going to be looking at courses that bring all developers up to speed, starting with a foundation in WebAssembly & Blazor before moving onto the more technical courses.


“WebAssembly: The Big Picture” Course

WebAssembly is the foundation upon which Blazor was built.  Anyone looking to become a skilled Blazor developer should definitely invest the time to learn about WebAssembly, including its origins, history and intended use in the web development world.


This course is designed to take anyone, from any background, and give them the technical understanding of what WebAssembly is, and how it works to provide a robust and fast platform for high performance web applications.  You are not just told facts about WebAssembly, but instead are taught the fundamentals of why WebAssembly does something to solve a particular problem that existed.


Course creator Barry Luijbregts does a fantastic job of clearly defining what WebAssembly is, before breaking down the technology’s origins, practical implementations, and how developers can leverage it for their own web applications.


The course moves on to discuss why WebAssembly is so disruptive to the web development world, and how it can and will impact online experiences now and in the future.  The final section focuses on some important concepts to keep in mind, and wraps up by recommending several other resources to continue learning about WebAssembly.

“Blazor: The Big Picture” Course

While the last course gave us everything we need to know about WebAssembly, this course does the same thing for Blazor itself, and is the natural follow-up to the WebAssembly course.  When you complete this course, you’ll know all the high-level details about Blazor, including the reason it was created and also when, where and how you should use it.


The course starts with a look at using Blazor on the client-side to develop rich user interfaces.  This includes practical examples on how to start working with Blazor yourself.  However, it should be noted that while there are some practical examples, this course is meant to be more of an overview of the technology and toolset itself, and not a guide to getting started.


After the opening section concludes, the next section focuses on connecting the dots between WebAssembly and Blazor.  As a whole, this is a course that does a great job at laying the foundational understanding of what Blazor is, and who should be excited about it.

“Blazer: Getting Started” Course

So far, we’ve looked at two Blazor courses that have prepared us with the proper understanding of what WebAssembly and Blazor are… now we move onto the first course that teaches us how to directly code in C# to build our own Blazor powered web applications.  This is a course that teaches you practical coding of HTML and C# while developing an example Blazor app along the way.


The first module is devoted towards constructing your first Blazor application.  The course guides you in creating a simple “Hello World” barebones application, and then uses it as a tool to build upon and teach you the rest of the fundamentals of Blazor.  You will learn the hosting models available for Blazor applications and deep dive into the different options you have when creating new Blazor projects inside of Visual Studio.  The first module ends with a focus on creating a Blazor app with your own layout, and then guiding you on through the debugging process.


The second module is all about working with data.  You are trained on using a REST API to access data, as well as using HttpClient calls.  The module continues by focusing on creating Forms with input validation and using Blazor to add new components and retrieve form data.  The entire section is very hands on, teaching you with practical examples and demos along with way.


The next module takes the app you created in the previous module, and shows you how to add additional features to it, including additional components or even JavaScript resources.   The course then shifts to client-side Blazor, which is a high-performance replacement for JavaScript.


The final module in this course is all about deploying your application.  This section walks you through all the server requirements and steps required to successfully deploy your new web application online.  This wraps up at the perfect place, bringing you from initial inception to project deployment in a single course!

“Creating Blazor Components” Course

Components are the basic building blocks of Blazor applications, so mastering their design and implementation is critical.  This course is dedicated to helping you maximize your knowledge of creating Blazor components so that you can create any type of web application imaginable.


The course starts with a basic overview of what Blazor Components are and how and why they are used.  The topic quickly shifts towards the underlying code that you use to create these components, as well as the necessary setup to properly work with data and listen for events with event handlers.


The second module in the course focuses on walking you through the process of creating a new interactive component from scratch, and then introduces parameters and properties, along with an in-depth explanation into how to capture data and react to events.


The final module brings it all together by teaching you how to leverage Razor templates to create reusable components and user interfaces for your web application.  This is the logical place for the course to end, since you now have all the skills and knowledge necessary to create your own one-off and reusable Blazor components.

“Designing and Building Enterprise Blazor Applications” Course

All the Blazor courses we’ve examined today have been relatively easy enough for a beginner to jump right into, but now we’ve moved onto a more advanced course for those who are trying to take Blazor application development to the next level.


This is a great follow up course to take directly after the last course on Blazer components because it picks up right where that course left off.  It starts by walking you through creating reusable components through a proper understanding of smart design patterns.  By building a foundation of proper application architecture principles, you are taught how to program smarter, not harder, using Blazor.


As the course continues, the underlying architectural best practices are explored.  This course explains not only how to do things in Blazor, but also why and when to do them. This section finishes up with a deep dive into dependencies and using services in Blazor.


Special attention is given to enterprise concerns such as security, scalability and reliability in the third module of this course.  The fundamentals of routing in Blazor is thoroughly explained, including advanced routing options and optional features.  It continues with a look at component reusability and portability with NuGet packaging and deployment.  The module finishes off with a look managing and working with application states.


A full breakdown of working with HTTP requests with Blazor comprise the bulk of the fourth module, while the final module seeks to tie all the previous modules together with an advanced level guide to working forms in Blazor.  This covers complex data as well as form validation and custom inputs, ending the course with practical examples of almost everything previously covered.
