analyzing-dotnet-performance
Scans .NET code for ~50 performance anti-patterns across async, memory, strings, collections, LINQ, regex, serialization, and I/O with tiered severity classification. Use when analyzing .NET code for optimization opportunities, reviewing hot paths, or auditing allocation-heavy patterns.

# .NET Performance Patterns
Scan C#/.NET code for performance anti-patterns and produce prioritized findings with concrete fixes. Patterns sourced from the official .NET performance blog series, distilled to customer-actionable guidance.
## When to Use
- Reviewing C#/.NET code for performance optimization opportunities
- Auditing hot paths for allocation-heavy or inefficient patterns
- Systematic scan of a codebase for known anti-patterns before release
- Second-opinion analysis after manual performance review
## When Not to Use
- **Algorithmic complexity analysis** — this skill targets API usage patterns, not algorithm design
