    SessionStateTempDataProvider instead of CookieTempDataProvider (want to store Form Model in TempData for Surface Controller form)

    Since 2017(!) The default TempDataProvider in MVC is Cookie (was SessionState)

    I want to store Form data in TempData. This is what my SurfaceController did in v7.

    I can serialize the Form model to TempData. BUT this creates MULTIPLE LARGE cookie in the browser which results in HTTP 400 Request Headers too large when I POST the form!

    There does not seem to be the possibility to change the provider in Startup.cs
