How to write my data into MS Project (.MPP) using C#

I am developing one application that will read and write MS Project File (i.e .MPP).

I am using .net framework 2.0 for it.Initially i was using MPXJ for reading .mpp file and i am able to read .mpp file successfully,but i can't create mpp file using MPXJ.

So currently i am searching a solution to write or create a .MPP file and insert task that i am having in my system.

Can you suggest my any solution to create MSProject File using C# and reading too.In short i can say that i want to export my data into mpp format.
