LLVMSharp are strongly-typed safe LLVM bindings written in C# for .NET and Mono, tested on Linux and Windows. They are auto-generated using [ClangSharp](http://www.clangsharp.org) parsing LLVM-C header files.
If you're on Windows, consider using the [**LLVMSharp 3.6 NuGet Package**](http://www.nuget.org/packages/LLVMSharp/3.6.0) - built from LLVM 3.6 Release.
