[Migration] Figure out a story for sharing session state with ASP.NET apps

[pranavkm]

As part of #40078, we want to figure out if there is a way to allow a frontend ASP.NET Core app and a backend System.Web based app to share session state.

• Can we support one of the existing session state providers such as SQL Server state provider?
• Could we build a state state provider using IDistributedCache? Is that sufficient for large apps?
• Are there framework components such as MVC's TempDataProvider that need to be investigated for compatibility?

Thanks for contacting us.

We're moving this issue to the .NET 7 Planning milestone for future evaluation / consideration. We would like to keep this around to collect more feedback, which can help us with prioritizing this work. We will re-evaluate this issue, during our next planning meeting(s).
If we later determine, that the issue has no community involvement, or it's very rare and low-impact issue, we will close it - so that the team can focus on more important and high impact issues.
To learn more about what to expect next and how this issue will be handled you can read more about our triage process here.
