Examples and additional notes

Related issue: TASKSNET-3334 - Implement a macro (VBA) removal operation.

MPPSaveOptions.ClearVba property can be used to specify that VBA macros should be removed when saving a project to MPP format:

var project = new Project("fileWithVBA.mpp");
project.Save("cleared.mpp", new MPPSaveOptions() { ClearVba = true });

Related issue: TASKSNET-11170 - Add writing of Group definitions to MPP format.

Starting with this release group data can be written to an MPP (MS Project 2003 and newer formats) file. Please note that MPPSaveOptions.WriteGroups property should be set to true in order to write group data. Otherwise, original group data will persist.
