Hi,

We didn't implement the drop database process because the tenant is being soft deleted. So you can revert back the deletion in the database. But despite wanting to do that, I created a gist. I drop the database right after the tenant is being deleted in TenantAppService.cs > DeleteTenant() method.

[AbpAuthorize(AppPermissions.Pages_Tenants)]
    public class TenantAppService : AbpZeroTemplateAppServiceBase, ITenantAppService
    {
        public IAppUrlService AppUrlService { get; set; }

//Inject necessary classes
         private readonly IDbContextResolver _dbContextResolver;
         private readonly IDbPerTenantConnectionStringResolver _connectionStringResolver;
//...

   public TenantAppService(IDbContextResolver dbContextResolver,
            IDbPerTenantConnectionStringResolver connectionStringResolver)
        {
            _dbContextResolver = dbContextResolver;
            _connectionStringResolver = connectionStringResolver;
            AppUrlService = NullAppUrlService.Instance;
        }

//My new drop database method
private async Task DropTenantDatabase(AbpTenantBase tenant)
        {
            var args = new DbPerTenantConnectionStringResolveArgs(tenant.Id, MultiTenancySides.Tenant)
            {
                ["DbContextType"] = typeof(AbpZeroTemplateDbContext),
                ["DbContextConcreteType"] = typeof(AbpZeroTemplateDbContext)
            };

            var connectionString = ConnectionStringHelper.GetConnectionString(
                _connectionStringResolver.GetNameOrConnectionString(args)
            );

            using (var dbContext = _dbContextResolver.Resolve<AbpZeroTemplateDbContext>(connectionString, null))
            {
                await dbContext.Database.EnsureDeletedAsync();
            }
        }


//I use the DropTenantDatabase() right after TenantManager.DeleteAsync();
    [AbpAuthorize(AppPermissions.Pages_Tenants_Delete)]
        public async Task DeleteTenant(EntityDto input)
        {
            var tenant = await TenantManager.GetByIdAsync(input.Id);
            await TenantManager.DeleteAsync(tenant);
            await DropTenantDatabase(tenant);
        }
