SharpDX - A new Managed DirectX/Multimedia API Library (one with Win8/Metro in mind too!)

SharpDX

"SharpDX is a full DirectX framework for the .NET Platform, including the newest DirectX technology. The top three features of SharpDX:

• SharpDX is providing the latest DirectX and Multimedia API to .Net with true AnyCpu assemblies, running on .Net and Mono.
• SharpDX is ready for next generation DirectX 11.1 technology and Windows 8 Platform. You can start to develop DirectX Metro style App in C# under Win8!
• SharpDX is the fastest Managed-DirectX implementation.

SharpDX is using a custom code generator from C++ headers in order to generate an efficient .Net interoperability with C++ DirectX API.

Features

The key features and benefits of this API are:

• Support for the following DirectX API:
  • Direct3D9 & Ex
  • Direct3D10
  • Direct3D10.1
  • Direct3D11 and Effects11
  • Direct3D11.1 (Win8 only)
  • Direct2D1 (including custom rendering, tessellation callbacks)
  • Direct2D1.1 (Win8 only)
  • DirectCompute
  • DirectWrite (including custom client callbacks)
  • D3DCompiler
  • DXGI
  • DXGI 1.1
  • DXGI 1.2 (Win8 only)
  • DirectInput 8
  • XInput
  • RawInput
  • DirectSound 8
  • X3DAudio
  • XACT3
  • XAudio2
  • XAPO
  • WIC
• API is generated from DirectX SDK headers : meaning a complete and reliable API and an easy support for future API.
• Managed platform independent .NET API : assemblies are compiled with AnyCpu target. You can run your code on a x64 or a x86 machine with the same assemblies, without recompiling your project.
• Lightweight individual assemblies : a core assembly - SharpDX - containing common classes and an assembly for each subgroup API (Direct3D10, Direct3D11, DXGI, D3DCompiler...etc.). Assemblies are also lightweight.
• Fast Interop : the framework is using a genuine way to avoid any C++/CLI while still achieving better performance than existing managed API. Check this benchmark.
• API naming convention mostly compatible with SlimDX API.
• Raw DirectX object life management : No overhead of ObjectTable or RCW mechanism, the API is using direct native management with classic COM method "Release".
• Easily mergeable / obfuscatable : If you need to obfuscate SharpDX assemblies, they are easily obfusctable due to the fact the framework is not using any mixed assemblies. You can also merge SharpDX assemblies into a single exe using with tool like ILMerge.
• Easily deployable as SharpDX are plain .NET assemblies, there is no need to install VC runtime or .NET GAC install.
• An integrated math API directly ported from SlimMath

I like the approach this project takes in that it's a pretty slim wrapper for the DirectX API, that's its foundation is tight coupling to he C++ headers.
