That doesn't sound correct. You may want to rethink that assertion.

See System.Environment.ProcessorCount.

But, per my previous comment: the idea that a particular piece of
software simply can't operate at all if there's only one CPU core
doesn't really make much sense. If in fact there is any
CPU-count-related limitation to your program, there should be a more
direct, results-oriented way to measure that and handle, as opposed to
selecting some arbitrary measure such as CPU cores.
