4. Re-inventing the wheel…
Logging to a text file?
Saving configuration?
…wishing Microsoft had done some of this for you?

5. Application Blocks What are Application Blocks?
Designed to address ‘wheel reinvention’
Have been around for a couple of years
Ranged from very simple helpers like the original data access block to powerful frameworks like UIP
Have evolved – input from lots of internal and external teams, but particularly from customer feedback

6. Feedback We love XML configuration We love “blog documentation”
We like deploying EVERYTHING
API job security

7. Enterprise Library Philosophy
Interoperable but independent
Minimize dependencies
Easier configuration
Scenario driven
Documented
Consistent
