MSDN-style core DNN documentation
Mr. Ernst Peter Tamminga has created a help (.CHM) DNN Core reference file, based on the inline code documentation comments found on the DNN source code. Pretty useful, if you want to have a quick browse at all the DNN classes. The latest download is based on DNN 4.8.4.
