How to make a .NET application “large address awar

问题:

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?

回答1:

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.

回答2:

From what I can tell you have to use the editbin utility shown in the existing answer. There does not appear to be any way to set the flag using Visual Studio .NET, it looks like they encourage people to compile for 64 bit if possible instead of using the flag

Add those lines to Post build:

editbin /largeaddressaware "$(TargetPath)"

From: vsvars32.bat in Visual Studio 2017
