ASP.NET Razor

Design

The Razor syntax is a template markup syntax, based on the C# programming language, that enables the programmer to use an HTML construction workflow.^{[clarification needed]} Instead of using the ASP.NET Web Forms (.aspx) markup syntax with <%= %> symbols to indicate code blocks, Razor syntax starts code blocks with an @ character and does not require explicit closing of the code-block.

The idea behind Razor is to provide an optimized syntax for HTML generation using a code-focused templating approach, with minimal transition between HTML and code.^[5] The design reduces the number of characters and keystrokes, and enables a more fluid coding workflow by not requiring explicitly denoted server blocks within the HTML code.^[3] Other advantages that have been noted:^[6]

• Supports IntelliSense – statement completion support
• Supports "layouts" – an alternative to the "master page" concept in classic Web Forms (.aspx)
• Unit testable
