  Hi,

  First of all thanks :).

  You need to create a new session of yours like this.

  public class AspNetZeroAbpSession : ClaimsAbpSession
  {
      public ITenantIdAccessor TenantIdAccessor { get; set; }
  
      public override int? TenantId
      {
          get
          {
              if (base.TenantId != null)
              {
                  return base.TenantId;
              }
  
              //Try to find tenant from ITenantIdAccessor, if provided
              return TenantIdAccessor?.GetCurrentTenantIdOrNull(false); //set false to prevent circular usage.
          }
      }
  
      public AspNetZeroAbpSession(IMultiTenancyConfig multiTenancy) 
          : base(multiTenancy)
      {
  
      }
  }
  

  public class TenantIdAccessor : ITenantIdAccessor, ISingletonDependency
  {
      private const string HttpContextKey = "AbpZeroCurrentTenantCacheItem";
  
      private readonly ITenantCache _tenantCache;
      private readonly IIocResolver _iocResolver;
  
      private readonly AsyncLocal _currentTenant;
      private readonly Lazy _abpSession;
      private readonly Lazy _tenancyNameFinder;
  
      private int? CurrentTenantId
      {
          get
          {
              if (HttpContext.Current != null)
              {
                  _currentTenant.Value = HttpContext.Current.Items[HttpContextKey] as int?;
                  return _currentTenant.Value;
              }
  
              return _currentTenant.Value;
          }
  
          set
          {
              _currentTenant.Value = value;
              if (HttpContext.Current != null)
              {
                  HttpContext.Current.Items[HttpContextKey] = _currentTenant.Value;
              }
          }
      }
  
      public TenantIdAccessor(
          ITenantCache tenantCache,
          IIocResolver iocResolver)
      {
          _tenantCache = tenantCache;
          _iocResolver = iocResolver;
  
          _currentTenant = new AsyncLocal();
          _abpSession = new Lazy(() => _iocResolver.Resolve(), true);
          _tenancyNameFinder = new Lazy(() => _iocResolver.Resolve(), true);
      }
  
      /// 
  
      /// Gets current tenant id.
      /// Use  wherever possible (if user logged in).
      /// This method tries to get current tenant id even if current user did not log in.
      /// 
      /// Set false to skip session usage
      public int? GetCurrentTenantIdOrNull(bool useSession = true)
      {
          if (useSession)
          {
              return _abpSession.Value.TenantId;
          }
  
          return CurrentTenantId;
      }
  
      /// 
  
      /// This method is called on request beginning to obtain current tenant id.
      /// 
      public void SetCurrentTenantId()
      {
          var tenancyName = _tenancyNameFinder.Value.GetCurrentTenancyNameOrNull();
          if (tenancyName == null)
          {
              CurrentTenantId = null;
              return;
          }
  
          CurrentTenantId = _tenantCache.GetOrNull(tenancyName)?.Id;
      }
  }
  

  Then replace IAbpSession with your session on your core module's PreInitialize method.

  Configuration.ReplaceService();
  

  Finally, use below code in your Global.asax's Application_AuthenticateRequest.

  if (User?.Identity != null && User.Identity.IsAuthenticated)
  {
      return;
  }
  
  using (var currentTenantAccessor = AbpBootstrapper.IocManager.ResolveAsDisposable())
  {
      currentTenantAccessor.Object.SetCurrentTenantId();
  }
