Hello, in my service i have condition that if true then must make some changes to database, but because i'm using UserFriendlyException it rollback all changes made, so i tried unitOfWork.Complete() but unfortunately the same behaviour
///////////////////////////////////
/////////// rest of code /////////
///////////////////////////////////
if (condition)
{
using (var unitOfWork = _unitOfWorkManager.Begin())
{
patient.IsActive = false;
_patientRepository.Update(patient);
unitOfWork.Complete();
}
throw new UserFriendlyException(18, L("CannotBookAppointmentIsAgeRestriction"), "");
}
/////////// another conditions /////////
///////////////////////////////////
/////////// rest of code /////////
///////////////////////////////////

UserFriendlyException is an exception and it rollbacks the transaction. this is by design. I suppose you want that this should work even other changes are rolledback:
using (var unitOfWork = _unitOfWorkManager.Begin()) { patient.IsActive = false; _patientRepository.Update(patient); unitOfWork.Complete(); }If so, use _unitOfWorkManager.Begin(TransactionScopeOption.RequiresNew) which will create an isolated UOW.

actually i tried as you mention
using (var unitOfWork = _unitOfWorkManager.Begin(TransactionScopeOption.RequiresNew)) { patient.IsActive = false; _patientRepository.Update(patient); unitOfWork.Complete(); }but i got this error

far away of this problem i always got this warning Abp.Logging.LogHelper - Can not find 'InternalServerError' in localization source 'AbpWeb'!
although i extended AbpWeb sources as explained here but it doesn't work [http://www.aspnetboilerplate.com/Pages/Documents/Localization#DocExtending])
thank you

An entity can not be shared by multiple dbcontext and multiple transaction. This is an exception of Entity Framework. In the second UOW, get entity from repository and then update it.
For the second problem, please provide additional info (like how you extended it), because this works for us.
