How to make a .NET application "large address aware"?

Assuming I have booted a 32-bit Windows Server with the /3GB switch, how can I make a .NET application use the additional address space?

Solution

  • The flag is part of the image header, so you need to modify that using editbin.

    editbin /LARGEADDRESSAWARE <your exe>

    Use dumpbin /headers and look for the presence of Application can handle large (>2GB) addresses to see if the flag is set or not.
