I have found this interesting for debugging, but also fun to hear web pages

Preserving State in Server-Side Blazor applications

Server-side Blazor is a stateful application framework. Most of the time, your users will maintain an ongoing connection to the server, and their state will be held in the server's memory in what's known as a "circuit". Examples of state held for a user's circuit include:

• The UI being rendered (i.e., the hierarchy of component instances and their most recent render output)
• The values of any fields and properties in component instances
• Data held in DI service instances that are scoped to the circuit

Occasionally, users may experience a temporary network connection loss, after which Blazor will attempt to reconnect them to their original circuit so they can continue.

I have a program that parses data from both delimited files and Excel spreadsheets. I was trying out Span to speed up parsing the delimited files, but the ref struct restrictions mean I can't just hide the two different file formats behind an interface (without the small added overhead of repeatedly pulling Spans from Memory).

But what if I just wrote the ASCII strings from the Excel spreadsheets into a byte buffer, so that the same Span based parser could be used with both file formats? Seems like the overhead cost could be fairly low, and the Excel parsing is already intrinsically slower because of the decompression & XML parsing costs, so I'd be willing to take a small performance hit there for a big gain on the delimited files.
