09-Dec-11 New features in LinqConnect 3.1

Entity Developer

• Capability for customizing the default Type Mapping Rules is implemented
• Capability for setting diagram options either globally for all diagram documents or separately for a particular one is implemented: the Diagram Appearance and Printing options can now be set through the Options dialog box
• Capability for setting such options as Environment, Diagram and Servers' to adjust the Entity Developer behavior, Model diagram behavior and Type Mapping Rules to your needs is implemented
• Capability for setting and defining the class property validation rules based on different engines (Data Annotation, Enterprise Library, NHibernate Validator) is added
• The 'Numeric Primary Key As Identity' Oracle option is added: if this option is checked, the "StoreGeneratedPattern" will be set to Identity by default for Number primary keys
• The 'Integer Primary Key As Identity' SQLite option is added: if this option is checked, the "StoreGeneratedPattern" will be set to Identity by default for Integer primary keys
• The documentation generation for Enum members is implemented
• The algorithm for forming the Navigation Properties names, when there are several FOREIGN KEY constraints between the same tables, is changed
• The documentation generation for navigation properties is implemented
• The "Recreate Model" option, allowing to rebuild the model from a scratch, is added to the "Update Model From Database" wizard
• The "GeneratePartialClass" template property to generate a partial class, which will not be overwritten by the designer, for each class in the model is added
• The behaviour is changed: the Navigation Property will not be displayed on the diagram and in Model Explorer if "Generate" is set to false for the appropriate association end
• The behaviour is changed: the Validate Max Length attribute is synchronized with the Max Length attribute of Property by default now
• The behaviour is changed: the Validate Required attribute is synchronized with the Nullable attribute of Property by default now
• The behaviour is changed: when selecting a property in the Model Explorer, the corresponding entity on the diagram does not expand if it is collapsed
• The behaviour is changed: the DATETIME2 data type is now used for columns, corresponding to System.DateTime properties, for Microsoft SQL Server 2008 and later
• The behaviour is changed: the 'Real' SQLite data type is now mapped to System.Double by default
• The behaviour is changed: database column comments are transfered to the Summary attribute of the Documentation property now
