Updating table with composite primary key using LINQ

I have a table named tblUserNetwork. It contains composite primary key on UserID and ConnectedToUserID

When i update the table networks.Update(networks), it gives error like this: 

Table dbo.tblUserNetwork contains a composite primary key field

What is the problem in updating.

I am updating many other table they don't have composite primary key they are updating well and good. But this does't, I cant understand this problem.

Is there ant problem with composite primary key
