The most popular JavaScript client-side web frameworks have been Angular, React, Vue, and others. In this course, we keep it .NET 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 are composed of 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 can run your client-side C# code directly in the browser, using WebAssembly (WASM). Because it is real .NET running on WebAssembly, you can reuse code and libraries from server-side parts of your application. We will be exploring many intricacies of the Blazor lifecycle, data flow, JavaScript interoperability, and general development activities and nuances. By the end of the course, you will have the skills and knowledge to build a web application using Blazor.
