It is also possible to get the DefaultNameSpace from the DTE. Very usefull if you are developing a Visual Studio Extension.

EnvDTE.DTE dte = GetService(typeof(DTE)) as DTE;
EnvDTE.Projects projects = dte?.Solution.Projects;
if (projects != null)
{
  foreach (EnvDTE.Project project in projects)
  {
    string defaultNameSpace1 = project.Properties.Item("DefaultNameSpace").Name;
    foreach (EnvDTE.ProjectItem projectItem in project.ProjectItems)
    {
      string defaultNameSpace2 = projectItem.Properties.Item("DefaultNameSpace").Name;
    }
  }
}
