IModel Interface

Definition

Namespace:

Microsoft.EntityFrameworkCore.Metadata

Assembly:

Microsoft.EntityFrameworkCore.dll

Package:

Microsoft.EntityFrameworkCore v9.0.0

Source:

IModel.cs

Metadata about the shape of entities, the relationships between them, and how they map to the database. A model is typically created by overriding the OnModelCreating(ModelBuilder) method on a derived DbContext.

public interface IModel : Microsoft.EntityFrameworkCore.Infrastructure.IAnnotatable, Microsoft.EntityFrameworkCore.Metadata.IReadOnlyModel

type IModel = interface
    interface IReadOnlyModel
    interface IReadOnlyAnnotatable
    interface IAnnotatable

Public Interface IModel
Implements IAnnotatable, IReadOnlyModel

Derived

Microsoft.EntityFrameworkCore.Metadata.RuntimeModel

Implements

IAnnotatable IReadOnlyAnnotatable IReadOnlyModel

Remarks

The service lifetime is Scoped. This means that each DbContext instance will use its own instance of this service. The implementation may depend on other services registered with any lifetime. The implementation does not need to be thread-safe.

See Modeling entity types and relationships for more information and examples.

Properties

Item[String]	Gets the value of the annotation with the given name, returning null if it does not exist. (Inherited from IReadOnlyAnnotatable)
ModelDependencies	The runtime service dependencies.
ModelId	This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release. (Inherited from IReadOnlyModel)

Methods

AddRuntimeAnnotation(String, Object)	Adds a runtime annotation to this object. Throws if an annotation with the specified name already exists. (Inherited from IAnnotatable)

FindEntityType(Type, String, IReadOnlyEntityType)	Gets the entity type for the given type, defining navigation name and the defining entity type. Returns null if no matching entity type is found. (Inherited from IReadOnlyModel)
FindEntityType(Type)	Gets the entity that maps the given entity class. Returns null if no entity type with the given CLR type is found or the given CLR type is being used by shared type entity type or the entity type has a defining navigation.
FindEntityTypes(Type)	Gets the entity types matching the given type.
FindLeastDerivedEntityTypes(Type, Func<IReadOnlyEntityType,Boolean>)	Returns the entity types corresponding to the least derived types from the given.
FindRuntimeAnnotation(String)	Gets the runtime annotation with the given name, returning null if it does not exist. (Inherited from IAnnotatable)
FindRuntimeAnnotationValue(String)	Gets the value of the runtime annotation with the given name, returning null if it does not exist. (Inherited from IAnnotatable)
FindRuntimeEntityType(Type)	Gets the entity that maps the given entity class, where the class may be a proxy derived from the actual entity type. Returns null if no entity type with the given CLR type is found or the given CLR type is being used by shared type entity type or the entity type has a defining navigation.
FindTypeMappingConfiguration(Type)	Finds the pre-convention configuration for a given scalar Type.
GetAnnotation(String)	Gets the annotation with the given name, throwing if it does not exist. (Inherited from IReadOnlyAnnotatable)
GetAnnotations()	Gets all annotations on the current object. (Inherited from IReadOnlyAnnotatable)
GetChangeTrackingStrategy()	Gets the default change tracking strategy being used for entities in the model. This strategy indicates how the context detects changes to properties for an instance of an entity type. (Inherited from IReadOnlyModel)
GetEmbeddedDiscriminatorName()	Gets the name to use for discriminator properties embedded in JSON documents. The default is "$type". (Inherited from IReadOnlyModel)
GetEntityTypes()	Gets all entity types defined in the model.
GetModelDependencies()	Gets the runtime service dependencies.
GetOrAddRuntimeAnnotationValue<TValue,TArg>(String, Func<TArg,TValue>, TArg)	Gets the value of the runtime annotation with the given name, adding it if one does not exist. (Inherited from IAnnotatable)
GetProductVersion()	Gets the EF Core assembly version used to build this model. (Inherited from IReadOnlyModel)
GetPropertyAccessMode()	Gets the PropertyAccessMode being used for properties of entity types in this model. (Inherited from IReadOnlyModel)
GetRuntimeAnnotations()	Gets all the runtime annotations on the current object. (Inherited from IAnnotatable)
GetTypeMappingConfigurations()	Gets all the pre-convention configurations.
IsIndexerMethod(MethodInfo)	Gets a value indicating whether the given MethodInfo represents an indexer access.
IsShared(Type)	Gets a value indicating whether the CLR type is used by shared type entities in the model. (Inherited from IReadOnlyModel)
RemoveRuntimeAnnotation(String)	Removes the given runtime annotation from this object. (Inherited from IAnnotatable)
SetRuntimeAnnotation(String, Object)	Sets the runtime annotation stored under the given key. Overwrites the existing annotation if an annotation with the specified name already exists. (Inherited from IAnnotatable)
ToDebugString(MetadataDebugStringOptions, Int32)	Creates a human-readable representation of the given metadata. Warning: Do not rely on the format of the returned string. It is designed for debugging only and may change arbitrarily between releases. (Inherited from IReadOnlyModel)

Extension Methods
