For some time I have used the K150 PIC programmer but I was tired of some strange behaviour so I purchased an Original PICKIT3 programmer/debugger.
During programming a 16F648A I receive the following message. "You're attempting to program a release platform with a debug build. Do you want to rebuild? This message keeps appearing time after time.
I do not understand the reason nor can I find a solution to this problem.
After indicating that I do not want to rebuild the programming continues without problems. Reprogramming results in the same message.
When moving over to the debugger the program reports: Target Device (00001100) does not match expected Device ID (00001120). For this I also can not find an explanation. The same message happens with different projects that are all running without a problem.
So two questions.
1. Why do I keep a sustained warning message during programming?
2. Why can there be a device mismatch?
I looked all over but can not find the reason.
Extra information:
The program is generated in debug mode since that is what i require for the on line debug procedure.

First, check that you aren't really trying to program a release platform with a debug build. You haven't said anything about whether you are in fact building in debug mode or release mode.
The second problem is because you have MPLAB set up for a 18F2510 target instead of the 16F648A that is actually connected to the programmer.
There is also the possibility of a bad connection between the programmer and the chip. Check the cable and the connectors. If all that looks fine, then maybe you are having a crosstalk problem. Try adding resistors and capacitors close to the PIC as I describe in my In-circuit Serial Programming writeup.
