Hello, @hilmoinb In the 8ce48f446c92faef8124349e5c5d8d0e95c0ae59 commit, I implemented this. Try to build from source and check. If successful, I will publish the nuget package. 

if(_twain32.Capabilities.CustomDSData.GetCurrent()) {
    _twain32.CustomData = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8, 8 };
    var _data = _twain32.CustomData;
}

download zip-archive from github unpack in vs add exist project to your solution add reference in your project (you must remove the nuget-package before)

Sorry i'm late to awnser, i tested it yesterday night and it's ok after a quick fix : twain32.cs TwRC _rc = this._dsmEntry.DsInvoke(this._AppId, this._srcds, TwDG.Control, TwDAT.CustomDSData, TwMSG.Get, ref _data); replace by TwRC _rc = this._dsmEntry.DsInvoke(this._AppId, this._srcds, TwDG.Control, TwDAT.CustomDSData, TwMSG.Set, ref _data);
