Features related to Entity Framework support
|
| |
To use the Entity Framework (v1 (.NET 3.5 sp1) or v4 (.NET 4)), you have all the designer features
at your disposal. Choosing the Entity Framework v1 or v4 as target framework allows you to generate code from the entity model in your
project. The following list gives an overview of the various aspects of that generated code, what options are available to you and which
functionality is available to you to configure the generated code and control what the generated code looks like.
- The Databases which are supported for Entity Framework:
- SQL Server 2000 and higher (EF v4 requires SQL Server 2005 or higher), CE Desktop 3.5 or higher
- Sybase iAnywhere / ASA
- MySql (DevArt provider)
- PostgreSql
- DB2
- Firebird
- Configure the generated code using a wide range of settings.
For Entity Framework v1 and Entity Framework v4, the
designer offers specific settings. For more details see
Entity Framework v1 settings
and
Entity Framework v4 settings
- Support for POCO entities, Self-tracking entities and 'Entity Framework v1 style entities'.
Through the selection of 'presets', you can select what kind of code is generated: code which uses POCOs, code which
uses self-tracking entities or code which is equal to the code generated by the Microsoft Entity Framework v1 designer.

- Designer constructs and their effect on the generated code
- Entities can be mapped onto a table or view and are available as normal classes.
- Fields mapped onto a related field are available at the entity class level.
- Value Type Definitions are generated as 'Complex Types', which is the term the entity framework uses
- Typed Lists are generated as linq queries. This allows you to design projections over model elements in the LLBLGen Pro designer
and use them using linq in your code.
More information...
- Action stored procedure calls are generated as methods on the generated datacontext class and use normal ADO.NET to call
the stored procedure.
More information...
- Retrieval stored procedure calls are also generated as methods on the generated datacontext and return
un-typed data in datatables/sets.
More information...
- Typed Views mapped onto a stored procedure resultset are resulting in a method onto the generated datacontext to call the
stored procedure and obtain a typed resultset.

- Generated code is compatible with Microsoft's own generated code.
If you are used to the generated code generated with
Microsoft's own T4 templates, using the generated code produced by LLBLGen Pro is very easy as the features found in Microsoft's own
generated code are also found in LLBLGen Pro's generated code.
- Generated code is source-control friendly and well documented.
The generated code is designed to be generated in the same form every
time so elements appear at the same position and are named the same. Every element is documented with XML document elements to make it
easy to produce XML Doc reference manuals.
- Generated code is extensible.
The generated code is designed to be extensible: both with generic base classes which can be used
to add code to all generated classes of a given kind (e.g. all entity classes) and through a partial class per generated class to implement partial methods
and add own custom code. The EDMX file is extensible through user code regions so you can
add your own XML to the EDMX file at various places inside safe regions which are preserved by the code generator across code generation
cycles.
