Open Rails's source code is arranged as a Visual Studio solution which can be built with the free Visual C# Express 2010, 2012 and 2013 products and the commercial Visual Studio 2010, 2012 and 2013 products.
One of the ways that the Free Software License (GPL) protects our rights is by requiring everyone who distributes software under the GPL to make the source available also. That way, everyone who uses the software can examine it and customize it if they wish.
The entire history of project development is archived in our Subversion repository, so visitors are able to extract not just the current version but all the previous ones too back to version 1 in December 2009.
