All of my build rules are being ignored...?

Use Build | Start (F7) to continue a failed build or Build Next Step (F10) to build only the next step.

To start building at a specific step, use Build From Cursor (Alt+F7) or Start From Cursor (Alt+F10), and then use F10 to build step-by step, or Build To Cursor (Ctrl+F10), or set a breakpoint and use F7 to build to the breakpoint.

You can also build or rebuild an individual group of steps (the selected step and all children) via Build Step Group (Alt+F8) or Rebuild Step Group (Shift+F8).

The purpose of Rebuild Selected is to allow explicitly rebuilding steps that might already be completed, are unchecked, or whose build rule evaluates false. Comparable to rebuilding your project being recompiling even if up-to-date, while building in Visual Build is akin to building your project (only what has changed/not complete yet).
