That error (14028) means that one or more of the files in the g:\sources\sxs folder are corrupted so they can't be used to enable .NET 3.5.<br />
DVD writers aren't very reliable unfortunately, they can sometimes corrupt files like this. I'd recommend burning a new DVD, or maybe using a USB thumb drive as they tend to be more reliable. It would also be a good idea to check that the ISO itself hasn't been corrupted as well.

Our group policies are blocking the install of 3.5, so I tried installing from the win8 install using :<br />

dism /online /enable-feature /featurename:NetFX3 /All /Source:e:\sources\sxs /LimitAccess<br />

But it fails with error:<br />

Unable to install frame .net 3.5 on win8

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

Windows 8 is a personal computer operating system developed by Microsoft as part of the Windows NT family of operating systems, with an emphasis on improving its user experience on tablets. In particular, these changes included a touch-optimized Windows shell based on Microsoft's "Metro" design language, the Start screen, a new platform for developing apps with an emphasis on touchscreen input, integration with online services, support for USB 3.0, Advanced Format hard drives, near field communications, and cloud computing. Additional security features were introduced, such as built-in antivirus software, integration with Microsoft SmartScreen phishing filtering service and support for UEFI Secure Boot on supported devices with UEFI firmware.
