Devart is glad to announce the release of the new versions of
ADO.NET data providers, enhanced database connectivity solutions, built
over the ADO.NET architecture, that support Entity Framework and LinqConnect ORM
solutions. New versions of dotConnect data providers offer you a new version of
Entity Developer 5.5 with a large number of improvements and LINQPad support in
New versions of dotConnect for Oracle, MySQL, PostgreSQL, and SQLite provide a LINQPad
driver that allows performing queries against the corresponding databases using
LinqConnect ORM models. Both static (for precompiled DataContext) and dynamic (for
automatic generation of context and entity classes) drivers are supported.
Code Generation Improvements
Entity Developer 5.5 offers the following new templates:
MVC Controller and MVC View Advanced - templates designed for generating
an ASP.NET MVC Controller and View for using entity classes in ASP.NET MVC applications.
Our MVC View Advanced template offers significant advantages over the standard MVC
Scaffolding template. It supports such advanced features as sorting, filtering,
Data Annotations Metadata - generates Data Annotations metadata classes and
decorate entity classes and properties with Data Annotations attributes that specify
validation rules, data display settings, and define metadata for Windows Communication
Foundation, Dynamic data, and WCF RIA Services.
Data Transfer Objects - template, designed for generating Data Transfer Object
Besides, some other templates were significantly improved. DbContext and POCO templates
now have a WCF Data Contract Attributes property for managing generation
of DataContract, KnownType, and DataMember attributes for classes and properties.
These templates now also have Implement INotifyPropertyChanging and Implement
INotifyPropertyChanging properties that control whether the generated classes
implement the corresponding interfaces.
DbContext template now can generate one of the following kinds of mapping: attribute
mapping (for simple cases), fluent mapping in the OnModelCreating method, and fluent
mapping in configuration classes.
Another new feature of code generation is that now you can generate context and
entity classes to different namespaces.
Create Model Wizard Improvements
Create Model Wizard was substantially improved. Now it is able to download and install
the required 'EnityFramework' Nuget package for Entity Framework 6 models, and for
models for Entity Framework 4 and 5 in case they use the DbContext template. It
also automatically adds references to Entity Framework specific assemblies to a
project when you add a new Devart Entity model to it.
Model First Improvements
Entity Developer 5.5 provides a number of settings to ease the Model First development.
It allows you to define a set of properties that will be present in all the new
entities, and when you create a new entity, these predefined properties will be
added to it automatically.
Model initialization settings now allow you to specify if the string properties
should be mapped to columns of unicode data type by default, and to set default
facets for all the numeric properties.
Working with attributes is greatly improved. Now it is possible to edit attributes
for several selected entities or properties at once. The Attributes page of the
Model Settings dialog box has now the refresh button for refreshing the available
attribute list for the selected assemblies.
Generate Database Wizard now can generate DROP statements for database tables before
CREATE statements. Update To Database Wizard offers a Recreate Database Tables setting
to drop and recreate tables instead of altering them.
When adding a model object (a class, complex type, or enum) from Model Explorer
to a diagram, or a table from Database Explorer to a diagram, now you can add them
with all the related objects.
