I just discovered a mysterious file in my (new) Visual Studio 2012 C++/CLI project: app.aps.
What is it meant for? Can I safely delete it? Should I ignore or include it in my commits to source version control?
It's a generated file for designer efficiency, you can ignore it in source control:
File created by Microsoft Visual C++, a software development application; stores the binary representation of a resource included with the project; enables the application to load resources more quickly.
