Running background tasks in Blazor with Web Workers: Exploring the .NET 11 preview - Part 1

This article examines the new Web Worker project template available in the .NET 11 SDK, focusing on how to add it to an existing Blazor WASM app and use it to run CPU-intensive tasks without blocking the UI. It explains the single-threaded nature of JavaScript engines, the limitations of Blazor WASM for heavy processing, and how Web Workers provide multi-threading via background threads. The post covers the template's code, message-passing communication, and practical steps to integrate it, offering a simpler alternative to previous methods. Written using .NET 11 preview 3, it is part 1 of a series aimed at Blazor developers seeking to improve app responsiveness.
