Handling Zip Files Without Third Party Lib in .NET 4.0?

Question

There is a similar question for 3.5 here:

Is there a built-in zip library in .NET 3.5?

that speculated that 4.0 would have it, but I can't find any info about it. If not, does anyone know why not? Seems like it would be fairly high on the list of things to include support for.

Answer 1

Take a look at the System.IO.Packaging namespace, which contains support for ZIP files, but not all of the features of ZIP files.

Still, it might be enough for your needs.

Answer 2

You may have already moved along, but ZiP API is added in .NET 4.5
