I'm not sure if this is a Nuget issue or a NEST issue, but every time I open my solution that uses the latest version of NEST, Visual Studio shows me http://nest.azurewebsites.net/nuget-install.html.
I'm using:
NEST version 1.0.0-beta1 (Prerelease)
Visual Studio Ultimate 2013 Version 12.0.21005.1 REL
NuGet Package Manager 2.7.40911.287
