Build folder should not be deleted.
When building a project in VS, the build process will fail if Application.ico is missing from the /Build/Windows/ folder.
User reported seeing this when checking in/checking out a project on different machines after following "Using Perforce..." documentation.
Tested by deleting Build folder for local project and attempting to build.
1. Create new code based project and build.
2. After project is created, delete Build/ folder inside project directory
3. In VS, attempt to build the project again
Build process will fail with "Error 1 error RC2135: file not found: ../../../../Build/Windows/Application.ico"
