  • ORM platform unification for usage in both server-side and client-side applications
  • Optional Session auto-activation
  • Optional Transactions
  • 'Unit of work' pattern support in UI applications
  • Greatly reduced number of assemblies (only 3 assemblies instead of 17)
  • F# language support
  • Visual Basic language support
  • Xtensive Practices initiative
  • and much more...
For further information see DataObjects.Net 4.4 Beta 1 Release Notes.

Due to major changes in API, usage of this release in projects, based on the previous version of DataObjects.Net, might require some fixing of assembly references or namespaces. Migration path is described in the Release Notes file.
