Sachin Singh · Answer

Blazor :- Blazor lets you build interactive web UIs using C# instead of JavaScript. 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. Tag Helpers:- Tag Helpers enable server-side code to participate in creating and rendering HTML elements in Razor files. For example, the built-in ImageTagHelper can append a version number to the image name.

Hello Chittaranjan, The tag Helpers are Razor page specific. Blazor uses components. From the usage perspective, they both look same. For example, when you have a tag helper, you can use that same like an HTML element where the tag helper properties can be used like regular HTML attributes. Blazor uses components. And components can be used same like HTML elements too. A component's properties can be accessed like an HTML attribute. So, when someone look into the usage code, he/she wont be bale to differentiate if an element is a Blazor component or tag helper. But, the way tag helper is created is different than blazor. Tag helpers render pure HTML but the Blazor component is not directly an HTML renderer. Rather Blazor component works integrated with the Blazor ecosystem. Theoretically, a razor page tag helper should have been usable in Blazor, but until today, Blazor cannot recognize Razor tag helpers (which is unfortunate). On the contrary, a blazor component can be used within the Razor page using the component element. For example, here is a sample usage of the Blazor component within Razor pages. "typeof(BugDetails)" param-IpAddress= "2.36.3.12" param-Id= "3" render-mode= "Server" /> Here, the BugDetails is the name of the Blazor component, and IpAddress, Id, etc are the properties of the component.
