Three Pillars

• XML Web Services
• General app to app communication
• Span implementations, firewalls, and geographic
  boundaries
• Applications Client Servers Services
• .NET Framework delivers a unified programming
  model
• Solutions become application networks
• Great user experience prevails
• Anytime, anywhere, on any device

Winforms vs Webforms

• Winforms
• Allows no-touch deployment
• GDI, sophisticated graphics
• High responsiveness
• Requires .NET framework installed
• Webforms
• No client deployment (Only Browsers)
• Server roundtrips
• DHTML for responsive UI
• Dynamic rendering
