Blazor was released almost five years ago, on September 23rd, 2019. Since then, the Blazor framework has evolved to introduce variations using web sockets via SignalR, WebAssembly (Wasm), and server-side rendering. Each approach has its benefits. However, developers have gravitated toward the simplicity of the Wasm model, likely due to a clear separation of client and server, an existing architecture of business APIs, and support for partly connected scenarios, amongst other reasons. As Rider developer Andrii Rublov explained in “How JetBrains Rider Implemented .NET WebAssembly Debugging”, the ..read more

The recording for Blazor Best Practices Borrowed From ReactJS, with Principal Consultant at Accenture, Brandon Pugh is now available on JetBrainsTV. Blazor took a lot of design decisions from React and other frontend frameworks and as a stateful component-based UI framework there is quite a bit of experience that can be transferred from one to the other. With any new technology, there is going to be a learning period as we experiment and gain experience and learn from mistakes made. After having deployed production Blazor apps for two different clients, I realized I was able to avoid some cos ..read more

We’ve captured insights from 26,348 developers worldwide in our annual Developer Ecosystem Survey 2023. This recap focuses on C# and .NET, but you can see what’s trending in other languages as well. Enjoy the results and commentary, and let us know what you think! Top Discoveries We know that ASP.NET Core is the most used .NET framework by C# developers – 56% use it. But Blazor just simply hasn’t had the uptake that Microsoft was hoping for. Blazor Server is only 16% of the ASP.NET development landscape with Blazor WebAssembly at 12%. More developers use the Minimal API feature (20%), released ..read more
