- ABP Framework version: v4.1.0-RC2
 - UI type: Blazor
 - DB provider: EF Core
 - Tiered (MVC) or Identity Server Seperated (Angular): yes
 - Exception message and stack trace: The following errors were detected during validation. - The SocialSecurityNumber field is required.
 - Steps to reproduce the issue:
 
Uncomment rows in _ModuleExtensionConfigurator.ConfigureExtraProperties
    private static void ConfigureExtraProperties()
    {
           ObjectExtensionManager.Instance.Modules()
              .ConfigureIdentity(identity =>
              {
                  identity.ConfigureUser(user =>
                  {
                      user.AddOrUpdateProperty<string>( //property type: string
                          "SocialSecurityNumber", //property name
                          property =>
                          {
                              //validation rules
                              property.Attributes.Add(new RequiredAttribute());
                              property.Attributes.Add(new StringLengthAttribute(64) {MinimumLength = 4});
                          }
                      );
                  });
              });
    }
No changes in UI (no columns or fields SocialSecurityNumber like https://docs.abp.io/en/abp/latest/Module-Entity-Extensions) After press Save button in Edit form we see error message: The following errors were detected during validation. - The SocialSecurityNumber field is required.

Hello,
I have the same issue.
What would it be the workaround at this moment if we need to add a new field to the AbpUser table using Blazor?

hi nparejod
I suggest you wait for Blazor's implementation.
You can also refer to the implementation of MVC. https://github.com/abpframework/abp/blob/dev/modules/identity/src/Volo.Abp.Identity.Web/Pages/Identity/Users/CreateModal.cshtml#L32
