Tools and libraries to generate .NET bindings for native C/C++ APIs, enabling interoperability with C# and C++/CLI.
CppSharp is a tool and library suite that generates .NET bindings for native C/C++ APIs. It automates the process of creating glue code to expose C/C++ libraries as managed APIs, solving the problem of manual and error-prone interoperability between native and .NET code. It supports C# and C++/CLI as target languages.
Developers working in the .NET ecosystem who need to integrate or expose existing C/C++ libraries, such as those building game engines, multimedia applications, or system-level tools.
Developers choose CppSharp for its accuracy (backed by Clang's parser), support for complex C++ features like multiple inheritance, and its extensibility through custom passes, which reduces maintenance overhead compared to hand-written bindings.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Leverages Clang's parser to create a detailed syntax tree, ensuring high-fidelity bindings even for complex C++ codebases.
Works on Windows, macOS, and Linux with both .NET and Mono runtimes, making it versatile for diverse deployment environments.
Supports C++ virtual method overriding, multiple inheritance via C# interfaces, and std::string, reducing manual work for sophisticated libraries.
Allows customization through user passes and type mapping, enabling tailored binding behavior for specific project needs.
Configuring CppSharp requires deep understanding of C++/.NET interop and Clang tooling, which can be time-consuming for new users.
Generated bindings introduce marshaling and managed-unmanaged transition costs, which may not suit performance-critical applications.
Being tied to Clang means unsupported C++ features or breaking changes in Clang can limit compatibility and require updates.
