UppercuT – Mark an Application Executable to Use More Than 2GB of Memory (Large Address Aware) - If you’ve ever built a .NET application that runs out of memory constantly, it’s because you are hitting a 2GB limit. You may have known about marking an assembly “/largeaddressaware”. You may have not. The process of doing this is actually somewhat easy once you learn about it. I would instead like to concentrate on automating this with UppercuT so I no longer have to think about it.
