Release Notes

  • Released two sets of components - compiled with VS2008/.NET 3.5 and VS2010/.NET 4.0
  • Added Visual Studio 2010 Solution and Project files (with .2010 suffix). Binaries are compiled to /bin/2010 folder. Using .NET framework 4.0
  • Started CoNatural.Dto project to support basic DTO functionality, including self tracking DTOs and DTO collections (work in progress).
  • BeforeExecute event added to IConnection to intercept commands before execution (for tracing, debugging)
  • Type mappers now support parameter mappings to indirect references (to scalar properties). ITypeMapperFactory caches indirect references to be used later in the mappings.
  • New useBatch flag in all IConnection.Execute methods that can generate a batch script.
  • Cloning data commands in data command factory (issues when reusing parameters fixed).
  • New option in Visual Studio AddIn - Command Designer : To deploy command as stored procedure.
  • New Visual Studio AddIn option - To create new (empty) CoNatural commands from project/folder popup menus. Created Command.tt T4 template to generate new empty commands or commands from existing stored procedures.

Refactoring:

  • Replaced HandleException virtual method with "Error" event.
  • Created execution context for single command and batch execution (for better code reuse and common interface for events).
  • Renamed method that executed commands as data readers returning first record as instance of T from T ExecuteScalar<T>(..) to 3 versions of overloaded T Execute<T>(...).
  • Materializer interface changed to receive materializer factory as first parameter (to create new materializers inside callbacks). Interface members renamed to "Materialize".
  • New batch execution method receiving binder callback that returns tuples of <object, ICommand> for more flexible transformations from source objects. (e.g. when binding entities to commands from RIA services ChangeSetEntries list).
  • ITypeMapper interface changed, and MapperCallback removed. Support for indirect references.
  • Refactored SqlClient db provider and ConnectionBase (to reuse more code).
  • Created CommandHost type as custom templating host.
  • Ignoring dynamic assemblies when compiling optimized materializers.


Important: If you are generating commands with the Visual Studio Add-In using VS2010/.NET 4.0 and the T4 templates included in this package, you must remove the language directive referencing .NET 3.5.
