What is the difference between using Entity framework self tracking entities and implementing Unit of work architecture? As i understand both are keep tracking of the objects, one db call for commit changes. So i cant figure out the difference of those. can some one point me about what should used in which case?
I'm using entity framework 5 with WCF service application.

You should use google and investigate on your own. The pros and cons of each should be readily available through a well formatted search. I mean unless you want a bunch of links from someone else who does the search for you.

yes i know that self tracking is kind of unit of work. that is why i'm asking any purpose of using unit of work instead of self tracking entities.

I have find out your response it is very clear to understand the answer:
1- They are the same when you look thir purpose because they will aply the changes all together to the databse
2- You can prefere Self Tracking because: Self Tracking simply ready to use with a variety of working capasity (Because it has many implemented methods)
3- You can prefere UnitOfWork because: You can add your methods according to your needs as like as RoleBack but also you can add those to the selftracking if you agree current implementation
