What is WCSF?

Microsoft Patterns & Practice best practice and standards guidance for web applications

What is WCSF?

Why to use it?

Value for Business: Common and consistent interface

reduced training costs Easy rollout of new functionality and

tasks Value from Architecture teams

Enables baseline architecture Create and distribute to developers

common development architecture Common appearance and behavior Modular approach

Why to use it?

Value for Development Teams: Great starting point - Iteration “0” – out of box Provides automation

Proven solution and project structure Integrate ASP NET site map, role manager and EntLib

security AB – out of box Creates test project Designer for page flow

Value for Operations Teams: Xcopy deployment; easy versioning across modules Module specific configuration files Consolidate number of common components Base service control from server side Common exception management system
