I'm trying to insert records in two tables, but getting the exception. Could you please help me to resolve the issue.

First I tried the below code.

await _testRepository.InsertAsync(test);

await _xyzRepository.InsertAsync(xyz);

Then I tried this code, But nothing is working for me.

try

{

var test = new Test();

using (var uow = _unitOfWorkManager.Begin(TransactionScopeOption.RequiresNew))

{

int? tenantId = _unitOfWorkManager.Current.GetTenantId();

using (_unitOfWorkManager.Current.SetTenantId(tenantId))

{

await _testRepository.InsertAsync(test);

var xyz = new XYZ();

await _xyzRepository.InsertAsync(xyz);

await _unitOfWorkManager.Current.SaveChangesAsync();

await uow.CompleteAsync();

}

}

}

catch (Exception ex)

{

throw new UserFriendlyException(ex.Message);

}

Exception
