MudBlazor是一个基于 Material Design风格开源、免费（MIT License）、功能强大的Blazor组件框架，注重易用性和清晰的结构。它非常适合想要快速构建Web应用程序的 .NET 开发人员，无需费力地处理 CSS 和 JavaScript。由于MudBlazor完全使用C#编写，因此你可以自由地调整、修复或扩展该框架。文档中有大量示例代码，能够帮助开发者快速理解和学习MudBlazor框架。
Blazor是一个使用 .NET框架和C#编程语言Razor语法构建Web应用程序的UI框架，它可以用于构建单页应用（SPA）和 Web服务，它使用编译的C#来操纵HTML DOM来替代JavaScript。Blazor 的目标是让开发人员使用C#编程语言来编写 Web 应用程序，使得C#程序员可以在一个熟悉的编程语言中完成整个应用程序的开发。这样既可以提高开发效率，也可以减少学习成本。
