Blazor uses the Razor template engine that generates HTML and serves to the web browsers. We can use both HTML and C# syntax all together in the Razor templates and Razor engine then compiles the Razor templates to generate the HTML. In Blazor Components we can use In-Line coding for the logics or we can separate it and can write the component functions into a separate C# class file. We use @code {} block for writing the C# functions along with HTML.
Blazor uses the “. razor” extension for Component identification.
