Extended Model Design and Runtime Capabilities in LINQ to SQL Compatible ORM Solution
Devart is glad to announce the release of LinqConnect 2.00, the new version of LINQ to SQL compatible ORM solution with extended functionality and enhanced own visual model designer – Entity Developer.
LinqConnect supports SQL Server, Oracle, MySQL, PostgreSQL, and SQLite. It is developed closely to the Microsoft LINQ to SQL technology, while extending its functionality, thus allowing LINQ to SQL developer to easily get started with LinqConnect. In addition to LINQ to SQL features, LinqConnect provides its own advanced functionality.
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. PLINQ
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.
The important enhancement in LinqConnect 2.00 is the upgraded model designer – Entity Developer, that delivers advanced Model First support and Update model from database functionality:
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 allows synchronizing your model with the database for Entity Framework and LinqConnect 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.
