Publisher tag isn't working for WMA files, works fine for FLAC, MP3, and WAV files

[jemiller00]

I'm trying to set the Publisher tag on WMA files as well as FLAC, MP3, and WAV files. FLAC, MP3, and WAV are all working fine, but, WMA is not.

Previously, I was using a different library from Microsoft to set the tags and found that the publisher tag is stored as "WM/Publisher".

If I read the tags out of the file, I find that the Tag.Publisher property is null. However, I can see that WM/Publisher is set in the file and I'm able to retrieve the value using the following code. This was set using Microsoft's library on Windows 10.

        file = File.Create(path);
        var publisher = ((TagLib.Asf.Tag)file.Tag).SingleOrDefault(cd2 => cd2.Name == "WM/Publisher")?.ToString();

I'm thinking there is a bug and maybe it's using a different field or something?

However, if I try to save the file using TagLibSharp, it is not saving the value.

I tested the code on equivalent FLAC, MP3, and WAV files, and it works fine for all of those. Just not for WMA.

If it's a bug, I'm wondering if there is a workaround, where I can set the value as one of the extra attributes that I was able to retrieve using the ExtendedContentDescriptionObject collection?

I was to successfully set the publisher using the following code.

        var t = file.Tag as TagLib.Asf.Tag;
        if (t != null) t.SetDescriptorString(Publisher, "WM/Publisher");

And retrieve it using:

        var t = file.Tag as TagLib.Asf.Tag;
        if (t != null) Publisher = t.GetDescriptorString("WM/Publisher");

I'm wondering if the Tag.Publisher property could be fixed to do this?
