Hi, Harry.
Since UltiDev Cassini hosts all application in its own process, crash of an application looks exactly like a crash of the server - Windows reports our service EXE as crashing. In order to get information on what is causing the crash, please take a look at Windows Event Viewer (Application). An attempt of using 32-bit ODBC driver in Cassini 64-bit process could cause the crash. In case you are running your application on a 64-bit system, be sure that MySQL driver you are using are 64-bit as well.
Please let us know if this information was helpful.
Best regards,
UltiDev Team.
