System.InvalidOperationException when starting new job

Hi,
i’m using Hangfire on my local development pc (VS 2013, IISExpress).
First time i tried to create and run job and it was successful. Later i decided to change a bit method name and parameters and after that i have every time exception like:

System.InvalidOperationException

The type shop.web.mvc.Infrastructure.DownloadDocumentRepository does not contain a method with signature EnqueueJob(JobBase)

All classes is in the web project. I tried to clear assembly cache, clean and rebuild solution, reboot and no luck so far.
Any suggestion what i’m doing wrong?

Thanks.

I think i found it, i figured out that i have 2 servers running, and the second one is running on old code base.

Update:
Solved the problem. Also, is there any way to choose which server will be used for job execution?
