Remarks
This interface is used during model creation and allows the metadata to be modified. Once the model is built, IKey represents a read-only view of the same metadata.
See Model building conventions for more information and examples.
Properties
| Builder |
Gets the builder that can be used to configure this key. |
| DeclaringEntityType |
Gets the entity type the key is defined on. This may be different from the type that Properties are defined on when the key is defined a derived type in an inheritance hierarchy (since the properties may be defined on a base type). |
| IsInModel |
Indicates whether this object is in a model, i.e. hasn't been removed from one. (Inherited from IConventionAnnotatable) |
| Item[String] |
Gets the value of the annotation with the given name, returning |
| Properties |
Gets the properties that make up the key. |
Methods

Adds annotations to an object. (Inherited from IConventionAnnotatable) |

| GetKeyType() |
Returns the type of the key property for simple keys, or an object array for composite keys. (Inherited from IKey) |
| 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) |
| GetPrincipalKeyValueFactory() |
Gets a factory for key values based on the key values taken from various forms of entity data. This method is typically used by database providers (and other extensions). It is generally not used in application code. (Inherited from IKey) |
| GetPrincipalKeyValueFactory<TKey>() |
Gets a factory for key values based on the key values taken from various forms of entity data. This method is typically used by database providers (and other extensions). It is generally not used in application code. (Inherited from IKey) |
| GetReferencingForeignKeys() |
Gets all foreign keys that target a given primary or alternate key. |
| GetRuntimeAnnotations() |
Gets all the runtime annotations on the current object. (Inherited from IAnnotatable) |
| IsPrimaryKey() |
Returns a value indicating whether the key is the primary key. (Inherited from IReadOnlyKey) |
| RemoveAnnotation(String) |
Removes the annotation with the given name from this object. (Inherited from IConventionAnnotatable) |
| RemoveRuntimeAnnotation(String) |
Removes the given runtime annotation from this object. (Inherited from IAnnotatable) |
| SetAnnotation(String, Object, Boolean) |
Sets the annotation stored under the given name. Overwrites the existing annotation if an annotation with the specified name already exists. (Inherited from IConventionAnnotatable) |
| SetOrRemoveAnnotation(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 |
| 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 IReadOnlyKey) |
