How does LINQ affect transaction isolation anomalies in high concurrency systems?

LINQ does not control isolation levels, but query timing can expose anomalies like dirty reads or phantom reads.

LINQ queries execute within database transactions defined by DbContext or explicit transaction scopes. However, if queries are split across multiple executions or contexts, they may observe different database states. This leads to anomalies such as non-repeatable reads or phantom reads, especially under lower isolation levels like Read Committed.
