Should I remove these sync repositories methods and then change to async methods?

abp/modules/tenant-management/src/Volo.Abp.TenantManagement.Domain/Volo/Abp/TenantManagement/ITenantRepository.cs

Lines 16 to 28 in 88ded4e

	Tenant FindByName(
	string name,
	bool includeDetails = true
	);
	Tenant FindById(
	Guid id,
	bool includeDetails = true
	);
	Task<List<Tenant>> GetListAsync(
	string sorting = null,
	int maxResultCount = int.MaxValue,

abp/modules/background-jobs/src/Volo.Abp.BackgroundJobs.Domain/Volo/Abp/BackgroundJobs/IBackgroundJobRepository.cs

Lines 8 to 11 in 4ce0381

	public interface IBackgroundJobRepository : IBasicRepository<BackgroundJobRecord, Guid>
	{
	List<BackgroundJobRecord> GetWaitingList(int maxResultCount);

Do you have intend to make GetListAsync of CrudAppService to async query? @hikalkan

[hikalkan]

Isn't it already async? Can you write more detail?
