Dear users,

Devart is glad to announce the release of dotConnect for Oracle 9.2, Devart ADO.NET data provider for Oracle with support for Entity Framework, LinqConnect (LINQ to Oracle) and NHibernate. The new version offers you support for Database-First approach in Entity Framework Core via Package Manager Console, support for JSON functionality of Oracle in Entity Framework, Oracle Advanced Security support in the Direct mode, and other features.

Entity Framework Core Database-First Support

Entity Framework Core supports the Database-First approach via the Scaffold-DbContext command of Package Manager Console. This command scaffolds a DbContext and entity type classes for a specified database.

Now dotConnect for Oracle also supports this command allowing you to quickly generate context and entity classes for an existing schema. In order for the database-first functionality to work, add the Devart.Data.Oracle.Entity.EFCore.Design.dll assembly to the project references in addition to other necessary provider assemblies.

JSON Functionality Support in Entity Framework

dotConnect for Oracle now supports the JSON functionality of the Oracle database in Entity Framework v4 - v6.

With the new provider version you will be able to use JSON-specific functions in your LINQ to Entities queries. For the list of the supported functions and examples of how to use them, you can read our blog article: JSON Support in Entity Framework v4 - v6 in dotConnect for Oracle, MySQL, and PostgreSQL

Oracle Advanced Security Support in the Direct Mode

The new version of dotConnect for Oracle supports Oracle Advanced Security Data Encryption and Oracle Advanced Security Data Integrity in the Direct mode. This also means that with the new version of dotConnect for Oracle you can connect to Oracle Data Cloud in the Direct mode without the need of Oracle Client software.

Other Improvements

Additionally, dotConnect for Oracle can now be installed without adding its assemblies to the GAC automatically. We also have added Batch Updates support in Entity Framework Core, which will improve dotConnect for Oracle performance.

Here is the complete list of dotConnect for Oracle 9.2.162 features:

  • The 'Do not install assemblies in the GAC' check box that allows disabling placing the provider assemblies to the GAC is added to the Install Wizard
  • Oracle ANYDATA type is supported in the Direct mode
  • The InitialLobFetchSize property of OracleCommand is supported in the Direct mode
  • The bug with generating an error when using OracleMonitor on Linux is fixed
  • The bug with losing Errors of an OracleException object when performing binary serialization is fixed
  • The bug with not using parameters value in ParentRelation data in OracleDataTable.SelectCommand is fixed
LinqConnect (formerly known as LINQ to Oracle)
  • The exception message for invoking CreateDatabase() for the model which includes an association with missing end is improved
Entity Developer

  • The behaviour is changed: the errors thrown by executing SQL statement CREATE/DROP USER are ignored
  • The bug with shortening PK, FK, IX, UX names in the Code-First CreateDatabase/CreateDatabaseScript functionality when config.CodeFirstOptions.TruncateLongDefaultNames=True is fixed
  • The bug with comparison in LINQ query when config.QueryOptions.UseCSharpNullComparisonBehavior=true is fixed
  • The bug with creating database objects in the same schema by several EF6 contexts in Code-First approach is fixed
  • The bug with adding all available objects to the model (instead of the selected ones) by Entity Data Model Wizard is fixed
  • The bugs with logical expressions in EF Core are fixed
