## What it is
CppSharp is a tool and library set that parses C/C++ headers and libraries and generates glue code to expose native APIs as managed .NET APIs (C# and C++/CLI). It can also be used standalone as a C# library for parsing native code into a rich Clang-based syntax tree.

## Use cases
- generate C# bindings for a C/C++ library
- consume a native C++ library from .NET code
- parse C/C++ headers into a syntax tree in C#
- add managed scripting support to a native codebase
- create P/Invoke wrappers automatically
- override C++ virtual methods from managed code

## When to choose
- you need automated C/C++ to .NET bindings instead of hand-writing P/Invoke
- you want a Clang-accurate C/C++ parser accessible from C#
- you need multi-platform, multi-ABI binding generation (Itanium, MS, ARM, iOS)
- you want Doxygen comments translated to C# XML docs in bindings

## When to avoid
- you target languages other than C# or C++/CLI (consider SWIG or language-specific tools)
- you only need simple flat C interop that plain P/Invoke handles easily
- your project is not on the .NET ecosystem
