dotNETInspector Best Practices: Finding Bugs and Performance Issues

dotNETInspector vs Competitors — Feature Comparison and Use Cases

Feature / Attribute dotNETInspector dnSpy ILSpy JetBrains dotPeek JustDecompile
Primary focus Static analysis, security inspection, runtime behavior tracing Decompiling + debugging (.NET) Open-source decompiler Decompiler + assembly explorer Decompiler with plugin support
Decompilation quality High — preserves structure and symbols where possible High — popular for debugging Good — fast and extensible Very good — integrates with JetBrains tooling Good — straightforward UI
Runtime tracing / instrumentation Yes — integrates tracing for behavior analysis Limited (debugging-focused) No (static only) No No
Security analysis (vuln scanning) Built-in rules for common .NET issues Community plugins available Plugins exist Limited Plugins available
Debugging support Integrates with runtime traces; some live inspection Full debugging (CLR debugging) Limited Read-only decompiler; no debugger Read-only
Extensibility / plugins Plugin API for custom checks Extensible with plugins Highly extensible Plugin ecosystem via JetBrains Extensible via plugins
Ease of use Designed for security analysts; moderate learning curve Friendly for devs; intuitive Simple UI; developer-friendly Familiar to JetBrains users Simple and approachable
Licensing / cost Commercial (offers trial) Open-source (free) Open-source (free) Free (commercial company) Free
Best for Security audits, incident response, behavior-driven analysis Debugging, reverse engineering, patches Quick decompilation and analysis Inspecting assemblies within JetBrains ecosystem Quick inspections and plugin-driven tasks

Use cases — when to pick each tool

  • dotNETInspector: Choose for security audits, vulnerability scanning, malware/incident analysis, and scenarios requiring both static inspection and runtime behavior tracing. Good when you need built-in security rules and tracing to reproduce suspicious behavior.
  • dnSpy: Best when you need to step through decompiled code, apply runtime patches, or debug third-party assemblies during development or reverse engineering.
  • ILSpy: Use for fast, open-source decompilation and extensibility via plugins for customized workflows.
  • JetBrains dotPeek: Pick if you already use JetBrains tools and want a polished, familiar UI for decompiling and exploring assemblies.
  • JustDecompile: Good for quick decompilation tasks with a simple interface and plugin support.

Quick recommendation

  • For security-first investigations and behavior tracing: dotNETInspector.
  • For interactive debugging and patching: dnSpy.
  • For free, extensible decompilation: ILSpy or JustDecompile.
