For Blazor developers, waiting for a full rebuild just to see a minor UI change has long been a top friction point. With .NET 9, Microsoft\u2019s Hot Reload for Blazor is finally mature delivering near-instant code updates and dramatically accelerating the dev cycle.<\/p>\n<p><\/p>\n<h2 class=\"wp-block-heading\">What Is Blazor Hot Reload?<\/h2>\n<p><\/p>\n<p>Blazor\u2019s promise full-stack .NET with C# everywhere has always been compelling.
