dotConnect for DB2 2.5 is released!

Post by Devart » Tue 24 Dec 2019 09:30

Dear users,

Devart is glad to announce the release of dotConnect for DB2 2.5, Devart ADO.NET data provider for DB2 with support for Entity Framework ORM. The new version offers you support for Entity Framework Core 3.1.

After Microsoft released Entity Framework 3 only for .NET Core 3 (.NET Standard 2.1), it caused certain criticism because of not supporting Full .NET Framework. Microsoft reacted to this criticism by making Entity Framework Core 3.1 compatible with .NET Standard 2.0, and thus, allowing developers to use it in projects, targeting Full .NET Framework as well as .NET Core.

So finally we also can support Entity Framework Core 3 for Full .NET Framework too, and we have added this support to all of our ADO.NET providers for cloud apps and for major databases.

dotConnect for DB2 now includes a new Devart.Data.DB2.Entity.EFCore.dll assembly for Entity Framework Core 3.1 support on Full .NET Framework. You can find it in the \Entity\EFCore3 subfolder of the provider installation folder.

dotConnect for DB2 also keeps supporting Entity Framework 6, and we have updated it to support Entity Framework 6.4.

Here is the complete list of dotConnect for DB2 2.5.909 features:
  • Visual Studio 2019 version 16.5 Preview is supported
  • The bug with using Toolbox component DB2DataSource in web projects of Visual Studio 2013, 2015, 2017, 2019 is fixed
