Monodevelop debugging: watch and locals panels remains empty.

I have a simple test script containing some public and private variables and a few breakpoints.
I am attaching the debug process to Unity and then I press play in Unity.
The breakpoints are working (the script execution stops when encountering a breakpoint) but the “WATCH” and “LOCALS” panels in Monodevelop remain empty. How do these panels work? How do I set a variable to be watched?

@kokodokoGames That’s cause u don’t play the game in unity, do it first and after go to Mono, there gonna be the variables.
