• ASP.NET (C#,VB.NET, Frameworks 1.x-2.x)
• ADO.NET (XML)
• SQL Server
• Web Services (SOAP, XML)
• etc.

• Role Based Security (exposed as namespace classes and web services)
• Bulk email, text messaging & faxing (exposed as namespace classes and web services)
• Other Namespace Classes (for dynamic SQL using ADO.NET Datasets, client and server side edit processing, dynamic scalability logic for server tier context switching, web service utilization statistics, etc.)

Many of these services can/are required on nearly all projects (regardless of the business solution).  For example, most solutions require some sort of role based security, most require dynamic reads/writes to and from a database, most need to be built to allow for unlimited scalability (application potentially spread across several servers), many will want to capture web service utilization statistics, etc.).
