>>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. Instead of using the ASP.NET Web Forms (.aspx) markup syntax with `B100`F9d9<%= %>`f`b symbols to indicate code blocks, Razor syntax starts code blocks with an `B100`F9d9@`f`b 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.`:cite-ref-mvc3rve-7-0[`F5bf`_`[7`#cite-note-mvc3rve-7]`_`f] 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.`:cite-ref-introducingrazor-4-1[`F5bf`_`[4`#cite-note-introducingrazor-4]`_`f] Other advantages that have been noted:`:cite-ref-pro1-8-0[`F5bf`_`[8`#cite-note-pro1-8]`_`f]

• Supports `F33f`_`[IntelliSense`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=IntelliSense]`_`f – statement completion support

• Supports "layouts" – an alternative to the "master page" concept in classic `F33f`_`[Web Forms`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=ASP.NET_Web_Forms]`_`f (.aspx)
