Oscillation due to long wires can kill a MOSFET. A resistor in series with the gate (as close to the gate as possible) will help supress oscillations, but you still need to keep all wires as short as possible, and bypass the supplies, as recommended by others. A good ground plane is also recommended.
With all due respect, kinarfi, if gate dv/dt were a problem, it would have been discovered a long time ago. Do you know how long MOSFETs have been around, and how many man-hours have been spent studying them? Your long wire and switch may have killed your MOSFET, but it was not due to gate dv/dt.
And I wasn't referring to you when I mentioned the ignored "challenge". I was referring to unclejed613.
