dotConnect for MySQL 6.00 is released!

Post by Devart » Tue 30 Nov 2010 13:56

Dear users,

Devart is glad to announce the release of the new version of dotConnect for MySQL, enhanced database connectivity solution built over ADO.NET architecture that offers Entity Framework and LINQ to SQL support. New dotConnect for MySQL offers new greatly improved Entity Developer 3.00 and LinqConnect 2.00.

LinqConnect 2.00

LinqConnect continues to improve, and now in version 2.00 it has many new features:
  • Batch Updates
    Now LinqConnect can execute DML statements in batches on SubmitChanges call, which improves performance of update operations.
  • Table Per Type inheritance
    New kind of inheritance hierarchy - Table per Type is supported now in addition to Table Per Hierarchy support.
  • ASP.NET Dynamic Data
    New templates for ASP.NET Dynamic Data projects are now included into LinqConnect package. This allows you to create ASP.NET Dynamic Data applications, using LinqConnect.
    LinqConnect 2.00 supports Parallel LINQ, which offers performance improvements for your applications, using LinqConnect.
  • Visual Studio Debugger Visualizer for DataQuery objects
    Now you can view SQL code, generated for your LINQ queries, while debugging your application. Debugger visualizer highlights SQL syntax of your query for better readability.
Entity Developer 3.00

The new version of Entity Developer delivers advanced Model First support and Update model from database functionality.
New Entity Developer provides advanced Model First support for both Entity Framework 1 and 4, for LinqConnect, and for LINQ to SQL. Model First approach implementation in Entity Developer offers automatic synchronization of mapping and storage part with the conceptual part of the model and easy to use wizards for synchronizing database with the model.
  • Synchronizing Database with the Model
    Entity Developer offers you two options for creating database based on your model. You may either generate a create script, that creates a new database, or use Update to Database Wizard that synchronizes an existing database with the model. This wizard makes only necessary changes to the database and retain the data if possible. Even changes inside entity are detected and resulted in ALTER statements, the table doesn't need to be dropped and created again. The wizard displays the tree of the changed objects and their changes, allowing you to choose which database objects need to be synchronized with the model, specify the renamed objects, etc.
  • Mapping Synchronization
    When automatic mapping synchronization is enabled, changes to the conceptual model are automatically applied to its mapping and storage part. For example, when you add a class to the conceptual part, a corresponding table is created in the storage part, and the class is automatically mapped to this table. Even the most complex conceptual part changes are supported - complex types, many-to-many associations, complex hierarchies. All these changes can be automatically reflected in the storage part. However you may make manual changes to the storage part, and they will be preserved when editing conceptual part.

Updating Model from Database

Update From Database Wizard was the most demanded feature at our UserVoice forum. The opinion of our users is important to us, so this feature was implemented in Entity Developer 3.00 as soon as possible.

Update From Database Wizard allows synchronizing your model with the database for Entity Framework, LinqConnect, and LINQ to SQL in a fast and convenient way. Unlike standard Visual Studio Update Wizard, Entity Developer Update From Database Wizard tries to preserve manual changes to the model where possible. The wizard detects all the database changes that can affect the model, e.g. created and deleted tables and views, their columns and foreign keys, column datatype changes, created and deleted stored procedures and functions, changes to their parameters etc.
