Yeah, I saw that - you're probably going to have to roll a custom pipe peek-and-read, which shouldn't be too difficult with C# given that it does provide enough abstraction to get at what you'd need to get at.

BTW, your code steered me in the right direction on how to properly send a SIGINT or SIGBREAK to a running console application, so apparently we're helping each other, hahaha... (The key turned out to be to do an AttachConsole to hook my app to the miner, disable signal handling in my app, send the signal, then unhook from it.)
