This release of Enterprise Library Contrib is based on the Microsoft patterns & practices Enterprise Library 5.0 core and contains the following:

Common extensions

• TypeConfigurationElement<T> - A Polymorphic Configuration Element without having to be part of a PolymorphicConfigurationElementCollection.
• AnonymousConfigurationElement - A Configuration element that can be uniquely identified without having to define its name explicitly.

Data Access Application Block extensions

• MySql Provider - MySql data provider for the Data Access Application Block.
• ODP.NET Provider - Oracle ODP.NET data provider for the Data Access Application Block.

Exception Handling Application Block extensions

• SqlException Wrap Handler - Exception handler that will wrap a SqlException with different exceptions based on the SQL Server error code.

Logging Application Block extensions

• LogParser - Combines the benefits of the Enterprise Library Logging Application Block with the ability to deserialize from a human readable log text file all LogEntry objects back. This enables sophisticated log filter capabilities with LINQ on normal log files (.NET 2.0 and Orcas samples) with very few lines of code. The Log parser now includes a TimeStamp parser.

Policy Injection Application Block extensions

• PIAB Call Handlers
  • CursorCallHandler: Temporarily changes the cursor while the next handler is being processed.
  • OneWayCallHandler: Queues the call to the next handler on the ThreadPool
  • SynchronizedCallHandler: Uses ISynchronizeInvoke to invoke the next handler
  • ThreadSafeCallHandler: Synchronizes access to the next handler
  • TransactionScopeCallHandler: Wraps the next handler with a TransactionScope

Query Application Block

• Query Application Block 5.0 - Next level of integration up from the DAAB providing a common interface for data stored in a DB, XML file or Web/WCF service. A full Application Block complete with configuration console designer and Unity support.

Validation Application Block extensions

• Validators
  • CollectionCountValidator
  • CompositeRulesetValidator
  • TypeValidator<T>
  • ObjectValidator<T>
  • EnumDefinedValidator
• Designtime enhancements
  • Lightweight type picker: An alternative type-picker that allows you to enter a typename in a text-box instead of using the tree-view.
  • Test command for Validation Rules: A dialog that allows to test and play around with validators inside the configuration console.
• Other extensions
  • DefaultValidators: The DefaultValidators class provides pre-allocated validators. Use them instead of instantiating new ones every time you need common validators.
  • ArgumentValidation: Validate pre/post conditions of method calls.
