Microsoft has released more of its ASP.NET Web development technology to open source

ASP.NET is a free web framework for building great web sites and applications.
Microsoft has opened the kimono a bit more on its ASP.NET technology in releasing the source code for ASP.NET Web API and ASP.NET Web Pages, also known as Razor.

In the past, Microsoft made the source code for ASP.NET MVC available under an open-source license. Now, the company has open-sourced another hearty chunk of its ASP.NET technology to the delight of some open-source players.

Microsoft has made the source code of ASP.NET MVC available under an open source license since the first V1 release. Microsoft have also integrated a number of great open source technologies into the product, and now ship jQuery, jQuery UI, jQuery Mobile, jQuery Validation, Modernizr.js, NuGet, Knockout.js and JSON.NET as part of it.

Microsoft will also release the source code for ASP.NET Web API and ASP.NET Web Pages (aka Razor) under an open source license (Apache 2.0)

Microsoft will also for the first time allow developers outside of Microsoft to submit patches and code contributions that the Microsoft development team will review for potential inclusion in the products. M/S announced a similar open development approach with the Windows Azure SDK last December, and have found it to be a great way to build an even tighter feedback loop with developers – and ultimately deliver even better products as a result.
