I have this method:

public MerchantModel GetMerchant(int MerchantID)
{
    MerchantModel retVal = null;

    using (TDCDataDataContext dc = new TDCDataDataContext())
    {
        var merchants = (from m in dc.tblMerchants
                            where m.RecordId == MerchantID
                            select new MerchantModel
                            {
                                RecordId = m.RecordId,
                                CategoryId = m.CategoryId,
                                Title = m.Title,
                                Icon = m.Icon,
                                Slogan = m.Slogan,
                                DateAdded = m.DateAdded,
                                Rating = m.Rating.Value,
                                WebSiteURL = m.WebSiteURL
                            }).ToList();

        retVal = merchants[0];
    }

    return retVal;
}

Do I have to use ToList to make this work? How do I query for just one Merchant and return the MerchantModel?

Thanks
