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

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

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

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

Enterprise Library Enterprise Library v1.1 released Jun 2005 Incorporates patches over 1.0 Compatible with .NET 2.0 What it is: Free source code Supported by PSS Architecture Neutral Not: Part of .NET Framework

Enterprise Library Vision Customer Y library Partner X library p&p Enterprise Library Customer Z library p&p blocks Partner blocks Customer blocks Block Specification Community blocks

Enterprise Library v1 Legend Dependency Plug-in Caching Exceptions Security Data Access Logging Dependency Crypto Plug-in Configuration Config Tool

Configuration Application Block Scenarios Read/Write Configuration Shared Configuration Integrated Configuration User Interface Encryption Block Provides De-couples code from storage Events for configuration change Framework for rich configuration user interface

Data Access Application Block Scenarios Connection Lifetime Management Unified Data Access API Configurable connections Block Provides Best-practice for using ADO.NET Connection string encryption Single line data access

Security Application Block Scenarios Authenticate users Authorise users Determine a user’s role Manage user profiles Cache credentials Block Provides Provider model for security A set of implementations Defaults to best practice

Cryptography Application Block Scenarios Encrypt data with symmetric keys Encrypt information for local access Hash passwords before storage Block Provides A simple object model for crypto Supports .NET crypto classes Supports DPAPI for keyless crypto Runtime configurable

Logging and Instrumentation Application Block Scenarios Logging Distributed logging Tracing Variable levels of detail Block Provides Single line model for logging Runtime configuration change with UI Sinks: EventLog, DB, .TXT, MSMQ, email, WMI …

Exception Handling Block Scenarios Consistent exception handling Exception transformation A way to add context to exceptions Block Provides Standard exception handling pattern Policy-based exception handling Built-in Actions: Wrap/Replace/Log.

Caching Application Block Scenario Offline persistent/encrypted data Local thread-safe data cache NOT a distributed cache Block Provides Provides optionally persistent/encrypted cache Supports plug-in cache persistence model Configured via Configuration Tool Thread-safe

Using Enterprise Library Enterprise Library is provided “as-is” Own the code Migration options Do nothing Side by side Rewrite

Future plans Enterprise Library V2 Coming up Enablement Migration into Framework Smart Client Enablement Guidance and Automation Toolkit Deeper community penetration .NET 2.0 / Visual Studio 2005 release Blocks revved to adhere to best practices of new platform Integration with new VS2005 experiences
