Implementation of the MusicBrainz API version 2.0 (requires .NET framework 4.5 or above).

• First class MusicBrainz entities Artist, ReleaseGroup, Release and Recording supporting asynchronous Get (lookup by MBID), Search and Browse.
• Advanced Search using Lucene query syntax (see search documentation for supported fields).
• Support for sub-queries in lookup requests (see MusicBrainz wiki for a list of supported inc parameters).
• Limited support for entity relationships.

More information about the MusicBrainz webservice can be found here.

Take a look at the wiki or the Hqub.MusicBrainz.Client example project.
