Define a class like this:

internal static class NativeMethods { // Import SetThreadExecutionState Win32 API and necessary flags [DllImport("kernel32.dll")] public static extern uint SetThreadExecutionState(uint esFlags); public const uint ES_CONTINUOUS = 0x80000000; public const uint ES_SYSTEM_REQUIRED = 0x00000001; }

Put this to the main method: (make sure its before application.run call)

// Set new state to prevent system sleep. (Note: still allows screen saver) var previousExecutionState = NativeMethods.SetThreadExecutionState(NativeMethods.ES_CONTINUOUS | NativeMethods.ES_SYSTEM_REQUIRED);
