Mono.Cecil is a C# library for inspecting, modifying, and generating .NET assemblies in ECMA CIL form. It provides a powerful object model over .NET binaries without requiring assembly loading via Reflection.
Use cases
- analyze .NET assemblies without loading them via reflection
- rewrite IL code in existing .NET binaries
- inject instrumentation or logging code into assemblies at build time
- build static analysis tools for .NET programs
- generate new .NET assemblies programmatically
- strip or modify metadata in compiled libraries
When to choose
- you need to read or rewrite .NET IL without loading assemblies into the runtime
- you're building a weaver, analyzer, or post-build IL transformer
- you need fine-grained control over .NET metadata and CIL generation
When to avoid
- you only need to inspect loaded types at runtime - use System.Reflection instead
- you're generating dynamic code at runtime - Reflection.Emit or source generators may fit better
- you need source-level rather than IL-level transformation
