I've been using AntDesign Blazor with AI-assisted programming for efficient full-stack development. However, I occasionally encountered issues with outdated property usage. Yesterday, an inspiration struck: I could create a CLI tool using .NET to query the JSON artifacts generated during our documentation build, and then add an MCP service for AI editors to call. Taking AntDesign.Cli as an example, this tool queries the latest API information for Ant Design Blazor components, effectively solving the problem of outdated model training datasets.

Radzen Blazor Components
Radzen Blazor is a set of 70+ free native Blazor UI components packed with DataGrid, Scheduler, Charts and robust theming including Material design and FluentUI.
Sure, why not use Blazor? It makes life easier for the developers who are primarily backend, to work on the frontend as well. Seems like the better choice. So what's next? The UI library. No shade to the long-time standing Bootstrap, but it's 2023 and there are so many other libraries one could use outside of Bootstrap; TailwindCSS, Bulma, Materialize CSS, just to name a few. Forget that for a minute, maybe we can use a Blazor component library to speed up development; there are a few in the market: MudBlazor, Telerik, Syncfusion, Radzen. Ultimately, we go with what we already have a license for, Telerik.

On the frontend, Blazor helps us maximize code reuse across chat and voice interfaces. With Blazor’s component model, we can build shared UI elements, manage state consistently, and even reuse validation and business logic across both modalities. For Blazor, we are using Bit Platform as we believe it has the state-of-the-art configuration to get the best from Blazor, both in functionality and performance.
