How to remove primary key from strongly typed Dataset

Question

How can I remove primary key or foreign key from strongly typed data-set in designer view ? I tried followings without success,

• Change unique key attribute to false
• Delete dataset and add it again

I am getting duplicate values for ID so it's intended but how can I stop this annoying error ?

If i preview the data there is no nulls being returned so it's just duplicate value i think..
