Here is a snap example of using the CSFreeDB in order to get the information about ab Audio CD using C# in async mode:

CSFreeDB-Snap-Example.cs

//Init the component
freeDB1.UserName = "Your email";
freeDB1.UserKey = "Your registration key";

// Tracks names:
foreach (string trckFreeDB in freeDB1.GetFreeDBInfoAsync(cboDevice.SelectedIndex).FreeDBTracksInfo)
{
    lstTracks.Items[cntr].SubItems[1].Text = trckFreeDB.ToString();
    cntr = cntr + 1;
}

//Album / Artist name:
if (cntr > 0)
{
    lblArtist.Text = "Artist: " + freeDB1.GetFreeDBInfoAsync(cboDevice.SelectedIndex).Artist;
    lblAlbum.Text = "Album: " + freeDB1.GetFreeDBInfoAsync(cboDevice.SelectedIndex).AlbumName;
    lblAlbumDiscID.Text = "DiscID: " + freeDB1.GetFreeDBInfoAsync(cboDevice.SelectedIndex).DiscID;
}
