Unit Testing for x86 LargeAddressAware compatibility

Question

Answer 1

So far I have only come across suggestions to mess with the Microsoft binaries listed in the question (i.e. use editbin.exe to manually "patch" them). But this has the following disadvantages:

• I need to repeat the patching once any future service pack is installed for Visual Studio
• I can no longer test in parallel: "regular" x86 and "extended" x86 with LAA

It seems a proper long-term solution would have to be implemented by microsoft?:
