My asp.net-application parse mpp-file and save data in db. Then I want to generate xml project-file with the same data using mspdi. All work good besides main first task. In process of parsing I get one task which is hidden in ms project and this task is parent of all others tasks. What is it? How can I add this "main hidden task" programmatically? Usual addition make it wrong.
UPD: I use mpxj.
