Specific analyzer pages used for code-pattern guidance

• CA1827, updated 2023-11-14

Older but still canonical sources used cautiously

• Reduce memory allocations using new C# features, Microsoft Learn, updated 2023-10-17
  • Still useful for ref, in, readonly struct, and copy-avoidance guidance, but older than the core 2025-2026 docs.
• Intermediate materialization, Microsoft Learn, updated 2022-09-02
  • Still canonical for LINQ materialization semantics.
• Deferred execution and lazy evaluation, Microsoft Learn, updated 2022-09-29
  • Still canonical for LINQ deferred-execution semantics.
• dotnet-stack, Microsoft Learn, updated 2023-03-14
  • Used only for narrow stack-snapshot guidance because the page is stale compared to the other diagnostics docs.

Explicit exclusions

• Framework-specific tutorials were intentionally excluded.
• GUI-first analysis flows were intentionally excluded.
• MCC-specific paths, code, and hot-path examples were intentionally excluded.
