Blazor apps are composed of reusable web UI components implemented using C#, HTML, and CSS. Both client and server code is written in C#, allowing you to share code and libraries. If you are interested in some more detailed case studies about Blazor you can visit the Blazor Customers Showcase from Microsoft.
This site is hosted on Microsoft Azure and was developed by the experts at Devessence using Oqtane, a CMS and application framework for Blazor and .NET MAUI. The site allows anyone to submit a Url for a Blazor site. It validates if the Url is valid and is in fact running Blazor (Server, WebAssembly, or the new Server-Side Rendering mode for .NET8). If so, it dynamically generates a 1280X1280 screen shot (configured with a 10 second delay to ensure the page is fully rendered). Please note that the screen shot service has difficulty with CSS specifications using 100vh. On a weekly basis it also has a scheduled job which re-validates the site and captures the latest screen shot (sites which are no longer valid are removed from the showcase).
