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
SessionStateTempDataProvider instead of CookieTempDataProvider (want to store Form Model in TempData for Surface Controller form)
Since 2017(!) https://github.com/aspnet/Announcements/issues/225 The default TempDataProvider in MVC is Cookie (was SessionState)
