Definition

Namespace:

Microsoft.EntityFrameworkCore

Microsoft.EntityFrameworkCore.dll

Package:

Microsoft.EntityFrameworkCore v5.0.0

Source:

ConventionPropertyExtensions.cs

Sets the factory to use for generating values for this property, or null to clear any previously set factory.

static member SetValueGeneratorFactory : Microsoft.EntityFrameworkCore.Metadata.IConventionProperty * Func<Microsoft.EntityFrameworkCore.Metadata.IProperty, Microsoft.EntityFrameworkCore.Metadata.IEntityType, Microsoft.EntityFrameworkCore.ValueGeneration.ValueGenerator> * bool -> Func<Microsoft.EntityFrameworkCore.Metadata.IProperty, Microsoft.EntityFrameworkCore.Metadata.IEntityType, Microsoft.EntityFrameworkCore.ValueGeneration.ValueGenerator>
