In VS 2010 it is the default setting that you step over properties and operators(like F10) even if you want to step into(F11). So here is the solution:
- Go to Tools > Options menu in Visual Studio.
- Go to Debugging > General menu item in left pane.
- In right view you will see an option Step over properties and operators (Managed only). Uncheck this option and then you are all set.
