Rectangle rabid = BFS.Monitor.GetMonitorBoundsByWindow(windowHandle);
//Rectangle rabid = BFS.Window.GetBounds(windowHandle);
int cbx = rabid.x;
int cby = rabid.y;
}
}

I just want the current monitors top left coordinate (adjusted for taskbar etc)
GetBounds works
GetMonitorBoundsByWindow throws error

Compile Failed.
Line 10: 'System.Drawing.Rectangle.x' is inaccessible due to its protection level
Line 11: 'System.Drawing.Rectangle.y' is inaccessible due to its protection level

.x and .y need to be .X and .Y

Fixed.
