Only a single value comparer is allowed for a given property.")]
public static void SetKeyValueComparer (this Microsoft.EntityFrameworkCore.Metadata.IConventionProperty property, Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer? comparer, bool fromDataAnnotation = false);static member SetKeyValueComparer : Microsoft.EntityFrameworkCore.Metadata.IConventionProperty * Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer * bool -> unit[<System.Obsolete("Use SetValueComparer. Only a single value comparer is allowed for a given property.")>]
static member SetKeyValueComparer : Microsoft.EntityFrameworkCore.Metadata.IConventionProperty * Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer * bool -> unit<Extension()>
