public Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionKeyBuilder HasKey (System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Metadata.IConventionProperty> properties, bool fromDataAnnotation = false);
public Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionKeyBuilder? HasKey (System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Metadata.IConventionProperty> properties, bool fromDataAnnotation = false);
abstract member HasKey : System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Metadata.IConventionProperty> * bool -> Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionKeyBuilder
Public Function HasKey (properties As IReadOnlyList(Of IConventionProperty), Optional fromDataAnnotation As Boolean = false) As IConventionKeyBuilder
