Configure Visual Studio auto complete

I recently installed Visual Studio 2015 on W10, and I noted it’s auto complete was a bit different from usual. For example, I always write OnTriggerEnter code like this:

    void OnTriggerEnter(Collider hit)
    {
        //Do something
    }

Now, everytime I try to use OnTriggerEnter, the autocomplete writes the code like this:

    private void OnTriggerEnter(Collider other)
    {
        //Do something
    }

How can I configure the autocomplete into my own templates?

Hey did you manage to figured this out? Cause i know the answer unless you already found a solution
