Hi Donovan,

my solution is to employ a 2-line by 5-pin header. One line is connected
to the PIC, the other line is to Your application. When the circuit is
in use, 5 jumpers are put on the headers. When programming, the 5
jumpers removed and the ICSP cable is plugged onto the appropriate line.

This works for me without any problems.

One more development to this: use a 6 pole header, the 6th pole is
connected to OSC1 and the nearby pin (the 5th) is GND in this case. When
you plug on the ICSP cable, it shorts OSC1 to GND, thus, oscillator
won't start, there's no problem with slow Vpp rise.

Your programmer will supply all the voltages during programming.

This "jumper" solution is the only rock-solid solution I could find out,
because the programmer doesn't like to see any capacitors on the pins it
handles.

Sincerely:
Bela
