Definition of Razor Pages:

Razor Pages is a fresh, more straightforward approach to developing online applications. Using a file-based routing technique eliminates most of the ceremony of ASP.NET MVC. Every endpoint is represented by a Razor Pages file in the Pages directory. We can begin by installing the ASP.NET Razor Pages template.

Razor Pages is a lightweight and flexible framework, and it gives the developer complete control over the HTML that is generated. For cross-platform server-side HTML production, Razor Pages is the framework of choice.

For server-side programming, Razor Pages uses the popular C# programming language and the simple Razor templating syntax for embedding C# in HTML mark-up to generate content for browsers dynamically.

Razor Pages are ideal for basic data entry or read-only pages. MVC has recently become popular in most programming languages for online applications, and there are advantages and disadvantages to it. As an MVVM solution, ASP.NET WebForms was created.

Instead of using controllers and views as a standard ASP.NET MVC application, Razor Pages focuses on page-based scenarios for web application development. When an HTTP request is received, it is routed through the middleware pipeline until it reaches a middleware component that can handle and process it.

Razor pages are more well-organised; they group files according to their function and design for the problem they solve. Each class it defines for functionality is backed by closely integrated code. They’re ideal for simple data entry pages because they’re read-only.

Razor Pages’ Benefits include the following:

• Any MVC programme includes Razor Pages by default.
• There are no controllers in a simple structural context.
• Flexibility to accommodate any application you choose to create
• It’s more organised and has special codes hidden under each page.
• As with ASP.NET Webforms, you can create web apps in less time.
• It provides total control over both HTML and URLs.
• There are fewer issues to deal with and more control with only one controller. 
• Look for any mistakes in the validation. 
• Dependency injection is used to keep track of dependencies.
• IDE’s built-in test features can be used to conduct testing.
