Your forums advise to use HTMLAgilitypack for reading HTML file in a VS 2010 WPF application. I have downloaded Nuget package to get latest version of HTMLAgilitypack.
My question is whether these two softwares i.e. Nuget and HTMLAgilitypack are free?
Yes they are:
HtmlAgilityPack uses Microsoft Public License (Ms-PL) https://htmlagilitypack.codeplex.com/license
Nuget uses Apache License 2.0 (Apache) https://nuget.codeplex.com/license
