Why has itself and the evidence it ever existed been removed?
Only a half year ago it was promoted on channel9 as Something that should be in everyones pack -- today the Microsoft Archive is "retired" and totally keeps quiet that the API code pack ever existed.
I can't answer the question of why, nor do I wish to speculate (maybe someone else closer to the issue can tell us what happened), but thankfully it's not completely gone. It looks like the binaries have been reuploaded to NuGet by other developers, although note that none of the packages are official ones from Microsoft.
The following packages were uploaded by NuGet user aybe:
- https://www.nuget.org/packages/WindowsAPICodePack-Core
- https://www.nuget.org/packages/WindowsAPICodePack-ExtendedLinguisticServices
- https://www.nuget.org/packages/WindowsAPICodePack-Sensors
- https://www.nuget.org/packages/WindowsAPICodePack-Shell
- https://www.nuget.org/packages/WindowsAPICodePack-ShellExtensions
As usual, to install them:
Install-Package WindowsAPICodePack-Core
Install-Package WindowsAPICodePack-ExtendedLinguisticServices
Install-Package WindowsAPICodePack-Sensors
Install-Package WindowsAPICodePack-Shell
Install-Package WindowsAPICodePack-ShellExtensions
Someone has uploaded it to GitHub.
A zip file containing the same files as the original executable self-extractor (i.e. the source, binaries and docs) is located here: https://github.com/jamie-pate/KeepSync/blob/master/contrib/Windows%20API%20Code%20Pack%201.1.zip.
Here's link (or this link) to original Windows API CodePack 1.1.
Seems like someone also posted it on CodePlex.
The original links are dead, but an Microsoft employee has uploaded the v1.1 original codepack to nuget. Search for winapicp at nuget, or use this link:
