See Model building conventions for more information and examples.

The current value for the property is stored in the ChangeTracker rather than being stored in instances of the entity class. (Inherited from IReadOnlyNavigationBase)

Extension Methods

AddAnnotations(IConventionAnnotatable, IEnumerable<IConventionAnnotation>, Boolean)	Adds annotations to an object.
GetAnnotation(IConventionAnnotatable, String)	Gets the annotation with the given name, throwing if it does not exist.
SetOrRemoveAnnotation(IConventionAnnotatable, String, Object, Boolean)	Sets the annotation stored under the given name. Overwrites the existing annotation if an annotation with the specified name already exists. Removes the existing annotation if `null` is supplied.
FindInverse(IConventionNavigation)	Obsolete. Gets the navigation property on the other end of the relationship. Returns null if there is no navigation property defined on the other end of the relationship.
GetIsEagerLoadedConfigurationSource(IConventionNavigation)	Returns the configuration source for IsEagerLoaded(INavigation).
GetTargetType(IConventionNavigation)	Obsolete. Gets the entity type that a given navigation property will hold an instance of (or hold instances of if it is a collection navigation).
SetIsEagerLoaded(IConventionNavigation, Nullable<Boolean>, Boolean)	Sets a value indicating whether this navigation should be eager loaded by default.
GetPropertyAccessModeConfigurationSource(IConventionPropertyBase)	Returns the configuration source for GetPropertyAccessMode().
SetField(IConventionPropertyBase, String, Boolean)	Sets the underlying CLR field that this property should use. This may be `null` for shadow properties or if the backing field for the property is not known. Backing fields are normally found by convention as described here: http://go.microsoft.com/fwlink/?LinkId=723277. This method is useful for setting backing fields explicitly in cases where the correct field is not found by convention. By default, the backing field, if one is found or has been specified, is used when new objects are constructed, typically when entities are queried from the database. Properties are used for all other accesses. This can be changed by calling SetPropertyAccessMode(IConventionPropertyBase, Nullable<PropertyAccessMode>, Boolean).
SetPropertyAccessMode(IConventionPropertyBase, Nullable<PropertyAccessMode>, Boolean)	Sets the PropertyAccessMode to use for this property.
AnnotationsToDebugString(IAnnotatable, Int32)	Gets the debug string for all annotations declared on the object.
GetAnnotation(IAnnotatable, String)	Gets the annotation with the given name, throwing if it does not exist.
SetIsLoadedWhenNoTracking(INavigationBase, Object)	Calls SetLoaded(Object, String, Boolean) for a INavigationBase to mark it as loaded when a no-tracking query has eagerly loaded this relationship.
FindInverse(INavigation)	Obsolete. Obsolete. Gets the navigation property on the other end of the relationship. Returns null if there is no navigation property defined on the other end of the relationship.
GetCollectionAccessor(INavigation)	Gets the IClrCollectionAccessor for this navigation property, which must be a collection navigation.
GetTargetType(INavigation)	Obsolete. Obsolete. Gets the entity type that a given navigation property will hold an instance of (or hold instances of if it is a collection navigation).

IsDependentToPrincipal(INavigation)	Obsolete. Obsolete. Gets a value indicating whether the given navigation property is the navigation property on the dependent entity type that points to the principal entity.
IsEagerLoaded(INavigation)	Obsolete. Obsolete. Gets a value indicating whether this navigation should be eager loaded by default.
ToDebugString(INavigation, 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.
GetCurrentValueComparer(IPropertyBase)	Gets a IComparer<T> for comparing values in tracked IUpdateEntry entries.
GetFieldName(IPropertyBase)	Gets the name of the backing field for this property, or `null` if the backing field is not known.
GetGetter(IPropertyBase)	Gets a IClrPropertyGetter for reading the value of this property. Note that it is an error to call this method for a shadow property (IsShadowProperty(IPropertyBase)) since such a property has no associated MemberInfo.
GetIndex(IPropertyBase)	Gets the property index for this property.
GetMemberInfo(IPropertyBase, Boolean, Boolean)	Gets the PropertyInfo or FieldInfo that should be used to get or set a value for the given property. Note that it is an error to call this method for a shadow property (IsShadowProperty(IPropertyBase)) since such a property has no associated MemberInfo.
GetPropertyAccessMode(IPropertyBase)	Gets the PropertyAccessMode being used for this property. `null` indicates that the default property access mode is being used.
IsIndexerProperty(IPropertyBase)	Gets a value indicating whether this is an indexer property. An indexer property is one that is accessed through an indexer on the entity class.
IsShadowProperty(IPropertyBase)	Obsolete. Gets a value indicating whether this is a shadow property. A shadow property is one that does not have a corresponding property in the entity class. The current value for the property is stored in the ChangeTracker rather than being stored in instances of the entity class.
