I can't get to use GZipStream class in my C# ASP.NET 4.5 application.
I get the error:
The type or namespace name 'GZipStream' could not be found (are you missing a using directive or an assembly reference?)
I tried using using System.IO;
but the System.IO.Compression
is not available in the "Reference Manager" in visual studio. I right click on the object name to see if Visual Studio finds the relevant reference but it does not.
Any suggestions?
