Constructors

RuntimeKey(IReadOnlyList<RuntimeProperty>)

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.

Properties

DebugView	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.
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).
IsReadOnly	Indicates whether the current object is read-only. (Inherited from AnnotatableBase)
Item[String]	Gets the value annotation with the given name, returning null if it does not exist. (Inherited from AnnotatableBase)
Properties	Gets the properties that make up the key.
ReferencingForeignKeys	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.
