ProjIO - where do the XML format files come from?

"Essential ProjIO is a native .NET library that enables .NET applications to read and write Microsoft Project XML-format documents without any dependence on Microsoft Project."

I have a goal of reading the contents of a .mpp file, without the need  to automate MS Project in the background, opening the .mpp file and then reading it. 

When I saw ProjIO I thought maybe this might be the solution.

Where do the "Project XML - format" files come from?

Are these created from within MSProject using their Save As XML format?


Thank you.

Hi Michael,


Thank you for your interest in Syncfusion products.


Regarding ".mpp" Project file:

Currently ProjIO does not provide support for MS Project files with extension .mpp.


Regarding XML (“.xml”) format Project file:

Currently ProjIO supports XML format MS Project files alone. Yes, the XML format project files created using Save as XML format option available in MS Project are supported in ProjIO.


For more information on ProjIO, refer below UG link:
