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.

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)
Model

Gets the model in which this function is defined.

ModelName

Gets the name of the function in the model.

StoreFunction

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.

TypeMapping

Gets or sets the type mapping for the function's return type.
