Answer 1

You need the asynchronously wait (with await) the Task returned from FromAsync:

public async Task FooAsync()
{
    AceVqbzServiceClient aceVqbzClientService = new AceVqbzServiceClient();
    await aceVqbzClientService.OpenAsync();
    IAceVqbzService aceVqbzTypeService = aceVqbzClientService as IAceVqbzService;

    await Task.Factory.FromAsync(
                       aceVqbzTypeService.BeginSaveUserOrganizationLinking,
                       aceVqbzTypeService.EndSaveUserOrganizationLinking,
                       objUser_OrganizationDetail, TaskCreationOptions.None);

    await aceVqbzClientService.CloseAsync();
}
