    public class RevertService : IRevert

    {

        public void Revert(string listName, int listItemId)

        {

            SPList oList = SPContext.Current.Web.Lists[listName];

            SPListItem oItem = oList.GetItemById(listItemId);

            if (oItem.Versions.Count > 1)

            {

                oItem.Versions.Restore(1);

<%@ServiceHost Language="C#" Debug="true"

    Service="WcfService.RevertService, $SharePoint.Project.AssemblyFullName$"

    Factory="Microsoft.SharePoint.Client.Services.MultipleBaseAddressBasicHttpBindingServiceHostFactory, Microsoft.SharePoint.Client.ServerRuntime, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

Add to this .csproj file:-
