Dear users,

Devart is glad to announce the release of dotConnect for MySQL 8.7, Devart ADO.NET data provider for MySQL with support for Entity Framework, LinqConnect (LINQ to MySQL) 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 MySQL in Entity Framework, 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 MySQL 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.Mysql.Entity.EFCore.Design.dll assembly to the project references in addition to other necessary provider assemblies.

JSON Functionality Support in Entity Framework

dotConnect for MySQL now supports the JSON functionality of the MySQL 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

Other Improvements

Additionally, dotConnect for MySQL 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 MySQL performance.

Here is the complete list of dotConnect for MySQL 8.7.794 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
  • The bug with looking up a column with decimal(19,4) type for MySQL is fixed
