Content Management Systems are a dime a dozen. Often organisations roll their own or extend existing solutions. Come hear about three popular ASP.NET CMS solutions from advocates that work closely with these products.
N2CMS is a light weight open source CMS built with C# and designed to run either with ASP.NET WebForms or ASP.NET MVC. While reasonably new, it’s approachable and easy to understand while also ensuring that extensibility points are available for power developers to create powerful .NET CMS websites.
Umbraco 4.5 is a open source CMS that supports ASP.NET User and Custom Controls natively. It is designed to run ASP.NET WebForms. The upcoming version 5 release (due next year) is based on ASP.NET MVC.
