Course Description

Overview

Writing modern web applications with a rich UI can be tedious. Blazor gives us .NET developers a chance to leverage our C# skills and build interactive web UIs. In this course, Modern Web Development with Blazor and .NET 5, you will gain the ability to build web applications using Blazor. We will explore: setting up your first Blazor application, how to work with an API and how data binding works, how to create and integrate JavaScript components.

When you have finished this course, you will have the skills and knowledge to build a web application using Blazor.

**UPDATE**

.NET 6 is now available and is shipped with Visual Studio 2022. This course has been updated to show how to create the project using Visual Studio 2022 and .NET 6.

Everything in this course is .NET 6 / .NET 7 compatible.

Otherwise, everything in the project will work just the same if you are not inclined to upgrade, even if you do.


Why Develop With Blazor?

The most popular JavaScript client-side web frameworks have been Angular, React, Vue and others. In this course, we keep it .NET by using Blazor, which is Microsoft's response to that monopoly.

Blazor allows you to create a Single Page Application on top of .NET Core and continue coding in C# (without needing to flip between C# and JavaScript too much). Blazor apps boast reusable web UI components implemented using C#, HTML, and CSS. Both client and server code are written in C#, allowing you to share code and libraries.


Blazor WebAssembly

Blazor can run your client-side C# code directly in the browser, using WebAssembly (WASM for short). Because it's real .NET running on WebAssembly, you can re-use code and libraries from server-side parts of your application.

We will explore many intricacies of the Blazor life-cycle, data flow, JavaScript Interoperability, and general development activities and nuances.

Deploy To Microsoft Azure Cloud

Azure Web App Service is key to deploying the API and Blazor Server Applications. We will also enlist Azure SQL for the Database to support our API.

Build A Strong Foundation in .NET 5 Programming With Blazor:

  • Build a Single Page Application client-side UI using Blazor and .NET 5 (or .NET 6)

  • Design a Database Using Entity Framework Core

  • Repository Pattern and Dependency Injection

  • Progressive Web Application (PWA) with Blazor

  • Understand the REST API and Client UI design principles

  • Global Error Handling with HTTP Interceptor

  • Understand C# and .NET Core Web Syntax

  • Understand how to customize Blazor app layouts

  • Understand User Authentication and Authorization in Blazor

  • Understand Identity Core and Identity Server

  • Handle Blazor Application User Authentication State

  • Consume REST Web API in Blazor Application

  • Manage Packages with NuGet Manager

  • Setup GitHub for Source Control

  • Deploy Applications and Database to Microsoft Azure

PREREQUISITES

To take this course, you should have at least 3 months of experience programming in C#. If you need to strengthen your C# fundamentals, you can take my C# beginner course C# Console and Windows Forms Development with LINQ & ADO .NET. If you need to brush up on your web development skills, you may also review Introduction To Website Development Technologies to learn the fundamentals of HTML, CSS, and JavaScript.

Content and Overview

To take this course, you must have some knowledge of Object Oriented Programming, if not C#. Even if you have little exposure to the .NET development stack, this course is beginner-friendly and full of development tips.

This is a huge course. Over 10 hours of premium content, but smartly broken up to highlight related activities based on each module in the application being built. We will also look at troubleshooting and debugging errors as we go along, implementing best practices, writing efficient logic, and understanding why developers do things the way they do. Your knowledge will grow, step by step, throughout the course, and you will be challenged to be the best you can be.

We don't do things the perfect way the first time; that is different from the reality of writing code. We make mistakes and point them out and fix them around them. By doing this, we develop proficiency in using debugging tools and techniques. By the time you have finished the course, you will have moved around in Visual Studio and examined logic and syntax errors so much that it will be second nature for you when working in the .NET environment. This will put your newly learned skills into practical use and impress your boss and coworkers.

The course is complete with working files hosted on GitHub, including some files to make it easier for you to replicate the demonstrated code. You will be able to work alongside the author as you work through each lecture and will receive a verifiable certificate of completion upon finishing the course.

Clicking the Take This Course button could be the best step you could take towards quickly increasing your income and marketability! Also, remember that if you don't think the course is worth what you spent, you have a full 30 days to get a no questions asked refund!


It's time to take action!

i enjoyed it so far. its audible, explanations are clear and i'm following well with what Trevoir says

By Mudiyanselage Hiran Eranda Wijeratne on 2/11/2023

This one is great, but still need some basic knowledge about blazer web development to completely understand the course. Otherwise, it could be hard to follow. It is not like that you can start from the beginning and learn everything from the scratch by just following this tutorial series. But is is a great way to kind of go through all the basic areas of blazer web development, if you have some knowledge to begin with. Thanks.

By Carlos Paredes on 11/29/2022

It is good to follow along and just copy what you do, but as a beginner, there are many concepts I cannot understand and I don't know WHY you do certaing things. Also there are many changes between videos that sometimes are clarified way later and sometimes even in the following Section, as well as bugs you seem to correct kind of improvising, so I would have prefer that you planned your course a bit more organized instead of just improvising some lessons... I would not recommend this to beginners or people who are expecting a clean, organized and well structured solid course... other than that, I learned a lot of course.

By James on 3/4/2022

Initially I thought this was the level of complexity I was looking for until... Decent amount of Blazor, large amount of "While off camera I did some coding" which is frustrating to the point of not bothering with the course anymore. Things like dispose, garbage collection, EF tracking, generic http client would be beneficial for an advanced Blazor course, but not for someone getting started. Seems to be a disconnect between Blazor instructors on this platform and the level of complexity they should be providing to their students, shame Blazor courses on here are not up to scratch with instructors like Stephen Grider or Colt Steele - I'd even pay more money for courses by them. Also your solution to .NET 6 Identity Server didn't work so ended up not having authentication for this project, might need to revisit that on your end because I set it up exactly the way you demonstrated it and it still didn't work. Relatively disappointed but it wasn't a __complete__ waste of money

By Moomin Troll on 2/25/2022

I have completed several of Trevoir's courses now. He explains things well and I like that he makes mistakes along the way, like any of us would! Not only does he answer my many questions, he will also look at your code if you get stuck. All I can say is that I wish more teachers on Udemy were like Trevoir. I always know that when I take one of his courses it will be thorough and well worth the money.

By Raymond van Hoorn on 1/22/2022

I am sorry to say, but there are constantly mistakes made during the course and therefore are a lot of errors in the code. There are some fixes, but most you have to fix yourself. Though I learn a lot of it fixing it, I presume that is not the purpose of the course. Also the link to the source code is missing. I have found the source code on GitHub: https://github.com/trevoirwilliams/CarRentalManagement-Blazor-WASM No offense to the instructor Trevoir Williams, because he has great knowledge and the instructions and the intentions he gives are good. When questions or feedback te response is always helpful and positive. A pleasant way to learn coding.

By Byron Bennett on 10/20/2021

This was exactly the course I was looking for. It starts with the new Blazor WebAssembly project template that includes a Client, Server (API), and Shared. Trevoir does an excellent job taking you step-by-step. Trevoir, thanks for this course. It's perfect!

By Michael Thomas Wheeler on 7/27/2021

great course! I learned what I was here for. The instructor answered the question I had pretty quickly and looked like he keeps up on everyone else's also. I liked the style of lecture and explanations of what we were doing along the way. I would definitely take another course with this instructor.

By David Wasserman on 6/27/2021

Excellent course. The instructor is very clear and to the point. The material is updated and relevant. I find this course easy to follow along as everything is very well explained. He even takes time to show common errors along the way, making it easier to deal with when you hit them on your own. I highly recommend this course.

By Viswanatha Swamy P K on 5/22/2021

I am only 50%. I really liked the way author explains. That shows his command over the subject. Also I really liked one another thing is he did not edit the errors which occurs, he fixes in front of us, so that will help us learn. That is really great. Excellent Job !!!
