Blazor and Web Development Fundamentals with .Net 7 from Udemy

In this course, you will learn the important underlying mechanics of all the different types of Blazor web applications. You will not have to write a single line of code to get through this course.

I am specifically steering away from jumping into the code, because without understanding the subtle differences between the different Blazor applications, you will end up 'coding in the dark', and you will get into issues for which there is not much support for currently. For example, if you don't understand the detailed mechanics of Blazor applications, you will not understand why you are getting CORS errors when making HTTP calls from your Blazor WASM application, or why you are getting database concurrency issues with Blazor Server and EF Core. And so on...

The course is divided into 5 parts. The first two parts of this course will focus on the theory of Blazor. In Parts 3 to 5, we will see those theoretical concepts from Parts 1 and 2 in action.

In Part 1, I will discuss what Blazor is, what the different types of Blazor applications are, and how the different hosting options work. I will also go into some detail about Single Page Applications and WebAssembly technology.

In Part 2, I will cover the .Net7 Framework, the Document Object Model, and the Render Tree concepts.

In Part 3, we will start getting more hands-on. We will create and run both Blazor Server and Blazor WASM applications from within Visual Studio. We will also start comparing the two application types in Part 3.

In Part 4, we will go into more detail with both Server and WASM applications. There will be a big focus on the runtime differences, which we'll explore using our browser developer tools.

Then finally, in Part 5, we'll create, run and install Blazor Progressive Web Applications (PWAs) onto our local machines. We will create 2 types of PWAs - a stand-alone PWA and an ASP(.)NetCore Hosted Application. We'll conclude Part 5 with some closing remarks about why PWAs are not always the best option for your use case, and what complications come with the development and testing of PWAs.

Reviews summary

Blazor fundamentals: theory and mechanics

learners say this course provides a strong foundational understanding of Blazor's underlying mechanics and hosting models like Server, WASM, and PWAs. Many find the instructor's explanations clear, particularly for complex topics such as the DOM, Render Tree, and SignalR. It's often seen as an essential prerequisite before tackling practical Blazor development. However, students note the course deliberately focuses on theory first, with later sections being demonstrations rather than interactive coding exercises, meaning you'll need supplemental coding practice to build applications. Some felt the title might imply a more hands-on coding approach than the course delivers.

Concepts like DOM, Render Tree are well explained.

"The instructor explains complex concepts like the DOM, Render Tree, and SignalR interactions very clearly."

"The explanation of Render Tree was particularly helpful."

"The pace was good, and the explanations were detailed but easy to follow."

Lays necessary groundwork before coding.

"This course provides a solid foundation for anyone starting with Blazor."

"Perfect for understanding the core concepts! The instructor is knowledgeable and explains things logically."

"This course is a prerequisite in my opinion before diving into building complex Blazor apps. It lays the groundwork solidy."

Deep dive into underlying Blazor mechanics.

"Excellent course! The focus on the underlying mechanics of Blazor Server and WASM is exactly what I needed."

"Good foundational course. It does a great job explaining the differences between Blazor hosting models and the technical concepts."

"Fantastic course! Cleared up so much confusion I had about how Blazor actually works under the hood."

'Web Development' title might imply coding focus.

"The title 'Web Development Fundamentals' is misleading; it should be 'Blazor Theory Fundamentals'."

"Not bad, but didn't meet my expectation for 'web development fundamentals' which usually implies coding."

Later parts are demos, not interactive coding.

"I felt the 'hands-on' sections (Parts 3-5) were more like guided walkthroughs or demonstrations rather than actual coding exercises."

"The promise of 'no code' initially is true, but then the later parts are just watching the instructor code/demo without much interactive practice."

"My main critique is the lack of hands-on coding exercises. The later parts are demos."
