and I try another way,
ICurrentTenant currentTenant = this.LazyServiceProvider.LazyGetRequiredService<ICurrentTenant>();
ITenantRepository tenantRepository = this.LazyServiceProvider.LazyGetRequiredService<ITenantRepository>();
if (allTenants == null)
{
using (currentTenant.Change(null))
{
allTenants = await tenantRepository.GetListAsync();
}
}
got the same error again: Object reference not set to an instance of an object.

Volo.Abp.Identity.Pro.Domain need standard 2.1?
So I must change all of my projects with Domain from NET Standard 2.0 to NET Standard 2.1.
