Use this skill to understand how .NET code works internally by decompiling compiled assemblies.
Decompiles .NET assemblies with ILSpy via dnx to inspect internal API implementations, NuGet packages, framework code, and binaries. Use for understanding compiled .NET behavior.
Inspects .NET packages, assemblies, types, members and APIs. Compares API versions, traces SourceLink provenance, and resolves dependencies with structured evidence.
Finds evidence for .NET packages, platform libraries, local assemblies, APIs, dependencies, SourceLink/symbol provenance, and version-to-version API changes.

Note: ILSpyCmd options may vary slightly by version.
Always verify supported flags withilspycmd -h.
