FatalExecutionEngineError with SimConnect C#

[Kaiii3]

Hey,

I got from time to time CTDs with my C# Application using the v45HF3 SimConnect DLL:

Exception:

Code: Select all

FatalExecutionEngineError

Stacktrace:

this is my code:

private IntPtr HandleSimConnectEvents(IntPtr hWnd, int message, IntPtr wParam, IntPtr lParam, ref bool isHandled)
        {
            isHandled = false;
            switch (message)
            {
                case WM_USER_SIMCONNECT:
                    {
                        if (this.SimConnect != null)
                        {
                            try
                            {
                                this.SimConnect.ReceiveMessage();
                            }
                            catch (Exception e)
                            {
                                Console.WriteLine(e.Message);
                                Console.WriteLine(e.StackTrace);
                            }

                            isHandled = true;
                        }
                    }
                    break;

                default:
                    break;
            }

            return IntPtr.Zero;
        }

Anyone an idea how to handle that, or what could cause this?
