The this.Frame.CanGoBack property changed between the time it entered and the time it got to the next line. A property that is implemented like the following: get { var result=backingvalue; backingvalue=!result; return result; } Would do it. Try changing the code to the following: var bool1=this.Frame!=null; if (bool1) { var...

Compilers are pretty smart; if either is actually faster in practice, both &1 and %2 will quite possibly compile to the same - faster - code. With a stupid compiler, I'd place a bet on &1 being at least as fast as the alternative since it maps to bit operations...
