Read and get acquainted with the entity model design features, the Entity Developer
To create the Entity Developer model for Visual Studio project, right-click the
project in the Solution Explorer and choose Add -> New Item from the popup
menu. In the displayed dialog select the type of the Devart model, e.g. Devart Entity
Model. Then specify the model name in the Name box and click OK. A
Create Model wizard will open.
Tip: You may design entity models with Entity Developer without Visual Studio
To generate model from existing database, choose Database First approach in Create
Model Wizard wizard and click Next. Choose the data provider and specify
the connection settings on this page, then click Next.
Select the check boxes to the right of the database objects to include them to the
model. You may include tables, views, stored procedures and functions, and Oracle
packages to your models.
Entity Developer allows flexible tweaking for the generated names of the entity
sets, classes, methods and their members. You may configure removing and adding
of prefixes and suffixes, case and pluralization.
After you finished configuring naming rules, click Next, set namespace and
Entity Container name, and click Next again. Now you may generate code for
the model immediately or clear the Run generator for model check box and
click the Finish button.
Diagram is the central part of Entity Developer that introduces visual model representation.
Diagram control contains classes with their properties, relations between them,
and complex types.
Tip: You can zoom in/zoom out diagram by using mouse wheel while holding
CTRL button or by specifying scale in the Zoom box.
Tip: Double-click any object on the diagram to open an editor dialog box
Tip: You can click Layout Diagram button to layout diagram automatically.
To create a complex type, parent or child class from a group of existing class properties,
just drag these properties from the class to the diagram sheet and choose the corresponding
action in the Choose Action dialog box.
Entity Developer allows you both to map classes to storage entities and to entity
SQL query. To set class mapping, right-click the class on the diagram and select
Mapping Details from the popup menu.
Tip: Mapping details can also be set for associations. Use the same way to
set mapping for the association.
With Entity Developer it is easy to map Create/Update/Delete operations to the stored
routines, added to the model. Right-click the class on the diagram and select Configure
Behavior from the popup menu. Then use appeared dialog box to set up the mapping.
Tip: For more information on using stored routines in the Entity Framework
models see our blog article.
When you are editing the model, Entity Developer automatically highlights all model
errors on the diagram and in the Model Explorer, and places the error and warning
messages in the Error List window.
Tip: If you have corrected your errors, but they still are in the Error List,
click the Validate Context Model button on the Model toolbar to refresh error
When designing model, and especially when debugging it, it is often necessary to
emulate model execution - to execute LINQ and Entity SQL queries. You can check
correctness of the entity mapping and view data returned by the model. Also, you
can view SQL, generated by LINQ and Entity SQL queries.
Tip:To create a query click the Create New Query button on the Standard
toolbar or press CTRL+Q.
Tip: Use Query Type combobox on the Query toolbar to select query
You can create own unique templates for the application code generation or use one
of the existing. New T4 like template language features the full power of C# or
Visual Basic in the templates, allowing virtually anything you may want for code
Tip: To open a template for viewing and, if applicable, editing, in the
Model Explorer area, expand the Templates node and double-click the
After you save the model and close the Entity Developer, the model code is automatically
updated in the Visual Studio, so you may use the model code in your application.
Tip: Double-click the model to open it in the Entity Developer if you need
to make some changes to it.
