Describe the solution you'd like

As you look at .NET 10 and the ability to store and restore application state if the circuit goes away, please keep in mind that not all data can be serialized via JSON.

Or to be more specific, you can serialize everything via JSON, as long as we have a hook to serialize our data into a byte[] or string that you can then put into the JSON.

In my case, I'm maintaining https://github.com/marimerllc/csla, which has its own serialization tooling. It is easy enough to convert CSLA state into a byte stream or even a string, but we'd need the Blazor API to allow us (or the app developer) to have the opportunity to use our serializer first to get the app state into a form where JSON is an option.

@rockfordlhotka thanks for contacting us.

We already have such hooks, as long as you give us a string, we will persist it (using persistent component state). We might include APIs that allow you to do your own serialization into a buffer and restore from it directly, but the ability to serialize your state into a string and pass it on to us is already there.

We will be using #26794 to track changes.

Excellent, thank you @javiercn

I was listening to Dan's recent interview where he was talking about this upcoming .NET 10 feature, and just wanted to make sure this was considered. Sounds like that feature is already implemented, which is exciting!
