This method expects an error code from an exception that your app has caught. IsDeviceLost will return true if the device is indeed lost, and the error code actually corresponds to device removal.

Copy
try { DrawStuff(); }
catch (Exception e) where canvasDevice.IsDeviceLost(e.ErrorCode)
{
    canvasDevice.RaiseDeviceLost();
}
