It has moved to https://github.com/NLog/NLog.Framework.logging.

You could have at least kept the rc1-final build of the package on nuget.org :(

@marcind can you use https://github.com/NLog/NLog.Framework.logging (though I'm not sure what NuGet feed that is on, if any)? @304NotModified has been working on that.

It was actually a mistake that we ever published the NLog provider we wrote - it was always intended as just a sample to prove out the design of ILogger. Of course you could just take the old sample code from here and re-use it...

Nah, it's all good. The sudden disappearance of the package broke our automated deployment, but turns out we're not using it anyway.
