Get content taxonomy using Ektron API

Ever wondered how to get the taxonomies that a content item is assigned to whilst using the Framework API?

In the older APIs there was a method called Ektron.Cms.API.Content.Taxonomy.ReadAllAssignedCategory().  This worked fine, but what if we want to use the fabby new Framework API?  Well here is how:

/// <summary>
/// Return the Taxonomy ID for a given content item. Only picks
/// the first taxonomy if there are more than one.
/// </summary>
/// <param name="contentId">Content Id</param>
/// <returns>Taxonomy ID</returns>
public long GetContentItemTaxonomyId(long contentId)
{
    long taxonomyId = default(long);
    var taxItemMgr = new TaxonomyItemManager();
    var itemCriteria = new TaxonomyItemCriteria();
    itemCriteria.AddFilter(TaxonomyItemProperty.ItemId, CriteriaFilterOperator.EqualTo, contentId);

    List<TaxonomyItemData> taxonomyItemsList = taxItemMgr.GetList(itemCriteria);

    if (taxonomyItemsList.Any())
    {
        taxonomyId = taxonomyItemsList.First().TaxonomyId;
    }

    return taxonomyId;
}

This method returns the Taxonomy Id but could easily be adapted to return the TaxonomyItemData object instead.
