ModelBuilder.Entity Method

Definition

Overloads

Entity(Type, Action<EntityTypeBuilder>)

Performs configuration of a given entity type in the model. If the entity type is not already part of the model, it will be added to the model.

This overload allows configuration of the entity type to be done in line in the method call rather than being chained after a call to Entity<TEntity>(). This allows additional configuration at the model level to be chained after configuration for the entity type.

Entity(String, Action<EntityTypeBuilder>)

Performs configuration of a given entity type in the model. If an entity type with the provided name is not already part of the model, a new entity type that does not have a corresponding CLR type will be added to the model.

This overload allows configuration of the entity type to be done in line in the method call rather than being chained after a call to Entity(String). This allows additional configuration at the model level to be chained after configuration for the entity type.

Entity(String)

Returns an object that can be used to configure a given entity type in the model. If an entity type with the provided name is not already part of the model, a new entity type that does not have a corresponding CLR type will be added to the model.

Entity(Type)

Returns an object that can be used to configure a given entity type in the model. If the entity type is not already part of the model, it will be added to the model.

Entity<TEntity>()

Returns an object that can be used to configure a given entity type in the model. If the entity type is not already part of the model, it will be added to the model.

Entity<TEntity>(Action<EntityTypeBuilder<TEntity>>)

Performs configuration of a given entity type in the model. If the entity type is not already part of the model, it will be added to the model.

This overload allows configuration of the entity type to be done in line in the method call rather than being chained after a call to Entity<TEntity>(). This allows additional configuration at the model level to be chained after configuration for the entity type.

Entity(Type, Action<EntityTypeBuilder>)

Performs configuration of a given entity type in the model. If the entity type is not already part of the model, it will be added to the model.

This overload allows configuration of the entity type to be done in line in the method call rather than being chained after a call to Entity<TEntity>(). This allows additional configuration at the model level to be chained after configuration for the entity type.
