Debugging on a 64-Bit Platform
This topic applies to:
Pro, Premium, and Ultimate
You can run Visual Studio 2010 on a 64-bit x64 platform under WOW64, which allows 32-bit Windows applications to run on 64-bit Windows operating systems. However, Visual Studio 2010 does not support IA-64 WOW. To debug IA-64 applications, you must debug remotely. For more information, see How to: Debug 64-Bit Applications.
When you debug a 64-bit application under WOW64, Visual Studio seems to perform normal local debugging. However, Visual Studio uses the remote debugging mechanism to connect to the 64-bit application, even on the same computer. Therefore, all considerations that apply to remote debugging apply to local debugging on a 64-bit operating system. For example, the external console window does not work on a 64-bit operating system.
