ID3.NET is a set of libraries for reading, modifying and writing ID3 and Lyrics3 tags in MP3 audio files.

The core library is a portable class library compatible with the .NET Framework 4 and higher, Silverlight 4 and higher, Windows Phone 7.5 and .NET for Metro style apps. It also contains non-portable libraries that provide additional platform-specific support.

ID3.NET also provides an extensible metadata discovery framework that can discover specific ID3 frame data (like album art, lyrics, etc.) from various online services such as Amazon,, Discogs and more.

ID3.NET has been moved to CodePlex. The code in the SourceForge SVN repository has been frozen and all further commits will happen on the CodePlex repository.
However, we will continue to provide current releases in SourceForge.
