You can do it in code:

Global.asax.cs

protected void Application_BeginRequest(){
    if (!Context.Request.IsSecureConnection)
        Response.Redirect(Context.Request.Url.ToString().Replace("http:", "https:"));
}

Or You could add the same code to an action filter:

public class SSLFilter : ActionFilterAttribute {

    public override void OnActionExecuting(ActionExecutingContext filterContext){
        if (!filterContext.HttpContext.Request.IsSecureConnection){
            var url = filterContext.HttpContext.Request.Url.ToString().Replace("http:", "https:");
            filterContext.Result = new RedirectResult(url);
        }
    }
}
