I think Sharp Architecture solves this quite well. What they do is put the unit of work inside an ASP .Net MVC Action Filter. Basically you can define a transaction Action filter such as

public class TransactionAttribute : ActionFilterAttribute
{
      public override void OnActionExecuting(ActionExecutingContext filterContext)
      {
         UnitOfWork.Start();
      }

      public override void OnActionExecuted(ActionExecutedContext filterContext)
      {
         UnitOfWork.Stop();
      }
}

and in your controller class put the Transaction attribute on your Action Result method
