2. Your First Look at Code First
Introducing EF to the Domain ClassesPutting the Pieces Together in an ExampleConvention for Table, Schema, and Column NamesConvention for KeysConvention for String PropertiesConvention for Byte ArrayConvention for BooleansConvention for One-to-Many RelationshipsOverriding Convention with ConfigurationsConfiguring with Data AnnotationsUnderstanding How Model Changes Impact Database InitializationData Annotations and Validation-Aware UIsConfiguring Code First with the Fluent APIOrganizing Fluent ConfigurationsSummary
3. Using Conventions and Configurations for Property Attributes
Working with Property Attributes in Code FirstLengthData TypeNullability and the Required ConfigurationMapping KeysCode First Convention Response to Unconventional Key PropertiesConfiguring the Key with Data AnnotationsUsing HasKey to Configure a Key Property in the Fluent APIConfiguring Database-Generated PropertiesConfiguring Database-Generated Options with Data AnnotationsConfiguring Database-Generated Options with the Fluent APIConfiguring TimeStamp/RowVersion Fields for Optimistic ConcurrencyCode First Convention and TimeStamp fieldsUsing Data Annotations to Configure TimeStampConfiguring TimeStamp/RowVersion with Fluent APIConfiguring Non-Timestamp Fields for ConcurrencyConfiguring for Optimistic Concurrency with Data AnnotationsConfiguring for Optimistic Concurrency with Fluent APIMapping to Non-Unicode Database TypesAffecting the Precision and Scale of DecimalsConvention for Precision and ScaleData Annotations for Precision and ScaleFluent Configuration for Precision and ScaleWorking with Complex Types in Code FirstDefining Complex Types by ConventionConfiguring Unconventional Complex TypesSpecifying complex types with Data AnnotationsSpecifying complex types with the Fluent APIWorking with More Complicated Complex TypesConfiguring Properties of Complex TypesConfiguring Complex Types with Data AnnotationsConfiguring Complex Type Properties with the Fluent APISummary
