C# API bindings

Description

The C# libvirt bindings are a class library. They use a Microsoft Visual Studio project architecture, and have been tested with Windows .NET, and Mono, on both Linux and Windows.

Compiling them produces LibvirtBindings.dll, which can be added as a .NET reference to any .NET project needing access to libvirt.

Requirements

These bindings depend upon the libvirt libraries being installed. In the .NET case, this is libvirt-0.dll, produced from compiling libvirt for windows.

GIT source repository

The C# bindings source code is maintained in a git repository available on libvirt.org:

git clone git://libvirt.org/libvirt-csharp.git

They can also be browsed online:

http://libvirt.org/git/?p=libvirt-csharp.git;a=summary

Usage

The class library exposes the LibvirtBindings namespace. This namespace exposes all of the needed types (enum, struct), and 2 main classes, libVirt and libvirtError.

The libVirt class exposes all of the interfaces of the libvirt library for handling virtualized domains.

The libvirtError class exposes all of the interfaces of the libvirt library for handling errors raised while using the library.

Authors

The C# bindings are the work of Arnaud Champion <arnaud.champion AT devatom.fr>, based upon the previous work of Jaromír Červenka.

Notes on testing

Windows testing is performed on Windows 7, with .NET 4, Visual Studio 2010, and MonoDevelop 2.4.

Linux testing is performed on Fedora 13 i686, with MonoDevelop 2.2.
