Remarks

This interface is used during model creation and allows the metadata to be modified. Once the model is built, IIndex 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 index.
DeclaringEntityType	Gets the entity type the index is defined on. This may be different from the type that Properties are defined on when the index is defined a derived type in an inheritance hierarchy (since the properties may be defined on a base type).
IsDescending	A set of values indicating whether each corresponding index column has descending sort order. (Inherited from IReadOnlyIndex)
IsInModel	Indicates whether this object is in a model, i.e. hasn't been removed from one. (Inherited from IConventionAnnotatable)
IsUnique	Gets a value indicating whether the values assigned to the indexed properties are unique. (Inherited from IReadOnlyIndex)
Item[String]	Gets the value of the annotation with the given name, returning `null` if it does not exist. (Inherited from IReadOnlyAnnotatable)
Name	Gets the name of this index. (Inherited from IReadOnlyIndex)
Properties	Gets the properties that this index is defined on.
