✅ Exception is caught, but not?

I have this piece of code

        try
        {
            await _dbContext.RunningTotals.AddAsync(new RunningTotal
            {
                Value = runningTotalDto.Value
            });

            await _dbContext.SaveChangesAsync();
            
            return new Result<OptionNone>(OptionNone.Default);
        }
        catch (Exception e)
        {
            return new Result<OptionNone>(e);
        }

        try
        {
            await _dbContext.RunningTotals.AddAsync(new RunningTotal
            {
                Value = runningTotalDto.Value
            });

            await _dbContext.SaveChangesAsync();
            
            return new Result<OptionNone>(OptionNone.Default);
        }
        catch (Exception e)
        {
            return new Result<OptionNone>(e);
        }

on await _dbContext.SaveChangesAsync(); I am getting exception. Breakpoint hits catch (Exception e) it goes into return new Result<OptionNone>(e); and then it just skips execution... it shows on IDE that exception is still present I don't understand nothing from it 😦

And what happens when you keep continuing?

oh I am using Rider one moment exception is goes through application but anyway, this is "break when exception is called" what I am saying it's Exception after catch it's still present. Like there was no catch :/ that's why I am confused

Or better yet, a simple unit test that shows the exception escapes to the async caller

@TeBeConsulting @phaseshift sorry for late response. I didn't get notifications 😦 there you go recording 🙂

fasadin•2y ago

that will be difficult as this is connecting with DB

Why did you stop the recording there?

there is lightning sign, which indicates that exception is "on going" one moment I will make new one

phaseshift•2y ago

It's still in scope When you exit the method, then it will be gone

hmmm ok you are guys right execution it's correct but that lightning was confusing to me because it does not disappear
