Razor is an ASP.NET programming syntax used to create dynamic web pages with the C# or VB.NET programming languages. Razor was in development in June 2010{{cite web|url=http://weblogs.asp.net/scottgu/archive/2010/07/02/introducing-razor.aspx|title=ScottGu's Blog - Introducing "Razor" – a new view engine for ASP.NET|work=asp.net|date=3 July 2010 }} and was released for Microsoft Visual Studio 2010 in January 2011.{{cite web|url=http://blogs.msdn.com/b/webdevtools/archive/2011/01/12/how-to-get-razor-syntax-support-in-visual-studio-2010.aspx|title=MSDN Blogs|publisher=Microsoft|work=msdn.com|access-date=2011-07-08|archive-url=https://web.archive.org/web/20120702131534/http://blogs.msdn.com/b/webdevtools/archive/2011/01/12/how-to-get-razor-syntax-support-in-visual-studio-2010.aspx|archive-date=2012-07-02|url-status=dead}} Razor is a simple-syntax view engine and was released as part of MVC 3 and the WebMatrix tool set.
Razor became a component of AspNetWebStack and then became a part of ASP.NET Core.{{cite book |last1=Chadwick |first1=Jess |title=Programming Razor: Tools for Templates in ASP.NET MVC or WebMatrix |date=9 September 2011 |publisher="O'Reilly Media, Inc." |isbn=978-1-4493-1716-4 |url=https://books.google.com/books?id=z3QlDSjr0jYC&q=ASP.NET+Razor |language=en}}
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.{{clarify|date=June 2013}} 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.{{cite web|url=http://www.asp.net/mvc/videos/mvc-3/mvc-3-razor-view-engine|title=MVC 3 - Razor View Engine|author=Jon Galloway|work=The Official Microsoft ASP.NET Site|date=19 February 2020 }} 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. Other advantages that have been noted:{{cite web|url=https://stackoverflow.com/questions/1451319/asp-net-mvc-view-engine-comparison|title=ASP.NET MVC View Engine Comparison|work=stackoverflow.com}}
- Supports IntelliSense – statement completion support
- Supports "layouts" – an alternative to the "master page" concept in classic Web Forms (.aspx)
- Unit testable
