Is there a way to tell Windows that it shouldn't swap out a particular processes' memory to disk?

Its a .Net windows service with fairly large memory usage. I got lot of physical RAM but the OS seems to move part of the process memory to the pagefile anyway.

You can use VirtualLock to prevent memory from being paged to disk, but I really think you're better off letting the OS manage the system's memory. It's pretty good at it, and I wouldn't second guess why the OS was swapping things to disk unless I really knew what I was doing.
