How do you handle concurrency tokens?
PICTURE THIS: A SENTENCE BECOMES TOKENS
The model does not read letters like humans. It reads these pieces, then predicts the next one.
Simple meaning
I mark a rowversion or token property and EF includes it in WHERE on update.
WHY — EF Core instead of guessing?
Why interviewers care about EF Core:
question about EF Core.
trade-offs, and what you would actually do on a .NET project - not buzzwords.
Name the idea, why it exists, then one short example.
End with when you use it and one common pitfall.
STEPS — What happens with tokens?
Before the model can read a sentence, it goes through these steps:
- 1I mark a rowversion
or token property and EF includes it in WHERE on update.
- 2Token IDs
Conflicts throw DbUpdateConcurrencyException.
- 3Embeddings
UI can reload and retry.
- 4Context mix
Attention looks at nearby tokens together.
- 5Next token
The model scores what should come next.
- 6Decode
IDs turn back into readable text.

Note: Adapt this scaffold to your own project — keep it under 60–90 seconds.
Key takeaway
I mark a rowversion or token property and EF includes it in WHERE on update. Conflicts throw DbUpdateConcurrencyException.
