No se puede convertir implícitamente el tipo 'vacío' en 'objeto'

En mi HomeController.cs configuré Session :

 public IActionResult Index(Mod m) { if (m.Password == "1234") { HttpContext.Session.SetString("Login", "True"); ViewBag.Login = "True"; } ... }

y quiero cambiar los valores de sesión en JavaScript:

 ... <input type="submit" value="Login" asp-for="Login" /> <a href="#" id="submit-link" class="button" onclick="submit();">Logout</a> ... <script type="text/javascript"> function submit() { var v = '@Context.Session.GetString("Login")'; alert(v); '@Context.Session.SetString("Login", "False")'; // ERROR --> Cannot implicitly convert type 'void' to 'object' } </script>

Session.GetString funciona bien, pero Session.SetString tiene un error. No sé cómo convertir vacío en objeto aquí.
