How to set the datetime format for the extra properties?

I have added 2 DateTime into extra properties for the IdentityUser

`ObjectExtensionManager.Instance.Modules()
.ConfigureIdentity(identity =>
{
identity.ConfigureUser(user =>
{
user.AddOrUpdateProperty( //property type: string
"MemberStartDate", //property name
property =>
{
property.Attributes.Add(new DisplayFormatAttribute() { DataFormatString = "{0:yyyy/MM/dd/}" });
property.DefaultValueFactory = () => "";

                            //validation rules
                            property.Validators.Add(context =>
                            {
                                if (context.Value != null)
                                {
                                    var startDate = (DateTime) context.Value;
                                    var endDate =
                                        context.ValidatingObject.GetProperty<DateTime>("MemberEndDate");

                                    if (endDate < startDate)
                                    {
                                        var message = LocalizableString.Create<LMSResource>("InvalidStartDate").Name;
                                        context.ValidationErrors.Add(
                                            new ValidationResult(
                                                message,
                                                new[] { "extraProperties.MemberStartDate" }
                                            )
                                        );
                                    }
                                }
                            });
                }
                    );
                    user.AddOrUpdateProperty<DateTime>( //property type: string
                        "MemberEndDate", //property name
                        property =>
                        {
                            property.DefaultValueFactory = () => "";
                            //validation rules
                            property.Attributes.Add(new DisplayFormatAttribute() { DataFormatString = "{0:yyyy/MM/dd/}" });
                        }
                    );
                });
            });`

And I have added the display format attribute for these 2 DateTime properties as well, but seems it does not work in UI part?

You can try add new DataTypeAttribute(DataType.Date).

Current version does not seem to support DisplayFormatAttribute
