We have an original zip library which uses the SharpZipLib and .NET 2.0. We need to research what is now possible in .NET 4.5 using System.IO.Compression and System.IO.Compression.ZipArchive.
Should we use .NET 4.5 libraries or use a 3rd party open source library?
Also, we need to be able to zip/unzip files larger than 4GB.
Samples, blogs, any help is welcomed.
