Console.WriteLine("Task Group Count: " + project.TaskGroups.Count);
foreach (var group in project.TaskGroups)
{
    Console.WriteLine("Index: " + group.Index);
    Console.WriteLine("Name: " + group.Name);
    Console.WriteLine("Show In Menu: " + group.ShowInMenu);
    Console.WriteLine();

    Console.WriteLine("Resource group Name: " + group.Name);
    Console.WriteLine("Resource group ShowInMenu" + group.ShowInMenu);
}

var otherProject = new Project(DataDir + "Blank2010.mpp");

// clear other project's groups
otherProject.TaskGroups.Clear();

// copy groups to other project
var groups = new Group[project.TaskGroups.Count];
project.TaskGroups.CopyTo(groups, 0);

foreach (var group in groups)
{
    otherProject.TaskGroups.Add(group);
}

// add custom task group
var customGroup = new Group
{
    Name = "Custom Group",
    ShowInMenu = true
};

if (!otherProject.TaskGroups.Contains(customGroup))
{
    if (!otherProject.TaskGroups.IsReadOnly)
    {
        otherProject.TaskGroups.Add(customGroup);
    }
}

// remove all groups
List<Group> groupsToDelete = otherProject.TaskGroups.ToList();
foreach (var group in groupsToDelete)
