AnyGantt can't use MPP directly - sample located at AnyChart.Com
uses third party server side .NET MPP converter component to create proper XML for AnyGantt. If you are interested - we can provide the source of such project, but implementing it requires .NET skills and sample uses MPJX
to convert MPPs.
We provide the sample converter project to AnyGantt customers, please contact support to receive downloading instructions.
