Is it possible to allocate executable memory? Are there alternatives for VirtualAlloc and friends?

Question

From http://msdn.microsoft.com/en-us/library/windows/apps/br205762(v=VS.85).aspx it seems that Metro Apps which want to go on the Store cannot use Win32 Virtual Memory Management routines like VirtualAlloc, VirtualProtect, etc. Are there WinRT alternatives for similar functionality? Is it possible to dynamically allocate and mark a particular area in memory as executable?

Answer 1

The Virtual* family of APIs is not a part of the metro SDK. 

Answer 2

Based on the limitations that they are putting on metro apps, and the verification they want to do before putting them in the app store, I would be very surprised if they were willing to let you dynamically generate code (thereby getting around all of those restrictions).
