DataObjects.Net 4.4.2 RC 2 is published

Today we are releasing DataObjects.Net 4.4.2 RC 2. The main advantage of DataObjects.Net v4.4.2 branch is migration to the latest version of PostSharp library (v2.1) that significantly improves compilation speed.

List of changes comparing to DataObjects.Net 4.4.2 RC 1:

• Fixed: Query translation error : group by with key of generic type
  
• Fixed: Bug with type cast if use Contains() method
  
• Fixed: DirectSqlAccessor.CreateCommand doesn't bind it to transaction
  
• Fixed: Memory leak when using compiled queries
  
• Improved: Tuple.Format() and TupleDescriptor.Parse() methods are up to 4x faster
  
• Fixed: Sorting in subqueries is omitted under certain conditions
  
• Added: Option to disable inclusion of SQL text in thrown exceptions
  
• Fixed: Legacy methods Query.Execute() don't work as expected
  
• Updated: PostSharp is updated to 2.1.5.12 version
  
• Fixed: Syntactic sugar (shortcuts) in Prefetch API doesn't work
  
• Fixed: Documentation contains outdated information
  
• Improved: Project upgrade tool is reworked
  

Migration path

Note: If a previous version of DataObjects.Net was installed (via installer), uninstall it and install the current version of DataObjects.Net. The easiest and recommended way is to utilize our ProjectUpgrader tool which resides in %DataObjectsInstallationPath%\Common\ProjectUpgrader directory. Select a project and hit "Run" and that's it.

However, you may also try to update the project file manually. To do that, update references to the latest DataObjects.Net components as well as to PostSharp library. When it is done, the project should reference Xtensive.Aspects.dll, Xtensive.Core.dll, Xtensive.Orm.dll version 4.4.2.0 and PostSharp.dll version 2.1.0.0
