We have discontinued this product because newer ASP.NET versions already include a similar attribute-based routing mechanism.
Getting started with MVC Extensions
Cobisi MVC Extensions (formerly SEO Extensions, which stands for Search Engine Optimization) is an advanced tool for software developers which allows to optimize ASP.NET MVC 3.0 and 4.0 web applications and sites for search engines. It comes with a powerful routing engine, which extends the standard ASP.NET routing module to provide a much more flexible way to define search optimized routes, and a complete set of classes that make customizing the entire routing infrastructure very easy.
By using MVC Extensions, applications register their routes in a new way and developers gain complete control over the URLs for these routes, have an easier routing configuration and see an overall increase in manageability over the target ASP.NET MVC applications.
MVC Extensions optionally integrates with Visual Studio (by way of the free Routing Assistant extension) and allows developers to easily explore the routes exposed by their websites, while also offering coding assistance for declarative routes (more about that in the next chapters) without leaving the IDE!
