Namespace:

Microsoft.EntityFrameworkCore.ValueGeneration

Properties

GeneratesStableValues	Gets a value indicating whether the values generated are stable. That is, the value will always be the same for a given property in a given entity, and does not depend on what other values may have been generated previously. For example, discriminator values generated for a TPH hierarchy are stable. Stable values will never be marked as unknown. (Inherited from ValueGenerator)
GeneratesTemporaryValues	Gets a value indicating whether the values generated are temporary or permanent. This implementation always returns false, meaning the generated values will be saved to the database.

Methods

Next(EntityEntry)	Gets a value to be assigned to a property.
NextAsync(EntityEntry, CancellationToken)	Template method to be overridden by implementations to perform value generation. (Inherited from ValueGenerator<TValue>)
NextValue(EntityEntry)	Gets a value to be assigned to a property. (Inherited from ValueGenerator<TValue>)
NextValueAsync(EntityEntry, CancellationToken)	Gets a value to be assigned to a property. (Inherited from ValueGenerator<TValue>)
WithConverter(ValueConverter)	Wraps this ValueGenerator such that it processes values converted with the given ValueConverter. (Inherited from ValueGenerator)
