Blazor "session" storage

[mrlife]

Is your feature request related to a problem? Please describe.

Ability to save simple values (e.g. string, int) that are available between route changes and page refreshes and understand how to implement it

Is there a convention that is detailed somewhere?

Describe the solution you'd like

I've read the popular issues here on this topic and haven't been able to find a solution. Things are alluded to but no path finds an actual solution.

There are recommendations for:

• HTML5 localStorage or sessionStorage but no locatable, built-in way to implement them via ASP.NET Core/Blazor
• ConnectionContext.Items, which I couldn't get to work due to DI errors
• adding actual ASP.NET HttpContext session to _Host.cshtml.cs, which is a limited workaround
• using a ClaimsPrincipal, which requires adding Authentication.

One of these will be fine if it solves it, but I can't tell if they are overkill. Ideally, there would be a package that gives access to the browser's sessionStorage (the one I'm likely to use), is used like a dictionary, and implements Data Protection.

There is a protected browser storage #18755 planned for 5.0.0-preview2 requested by @danroth27.
