When I tried to used Package Manage Console to install a package, ex. Install-Package UmbracoCms, I got the messages, and it took so long without any replies.
I found out the solution for this * problem from Nuget extension (ver. 3.0.60410.213) on VS 2015 RC. You can follow the steps below to solve it.
1. Uninstall Nuget extension from Visual Studio 2015 RC
2. Delete the folder in the directory showed below
3. Download the installation file of the older version of Nuget extension from this link: Download.
4. Extract the downloaded file to a folder on your machine.
5. Open Developer Commant Promt for VS 2015
6. Type this command to install it: VSIXInstaller [your_extracted_folder_path]\NuGet.Tools.vsix /admin
Example: VSIXInstaller c:\nuget14_VisualStudio\NuGet.Tools.vsix /admin
Press enter to start installing
Open Visual Studio 2015 and try again to see ‘the magic’ 😀

Thanks! Do you think this is a bug with Umbraco or NuGet? Cause other packages seems to work for me.
Anyways, thanks again. This solution works perfectly until the real version of VS is released.
I think Nuget, Nuget team’s still working on it, and many bug has been reported. Anyways, this is still a testing version 😀
I’ve created a new issue for this as assuming that people are working on something is always a bad idea (how would they know it’s an issue if nobody tells them) 🙂

Ps: Thanks for figuring out a solution to this, would never have thought of reverting to an older NuGet version!
Just a note for anybody who happens across this that the issue appears to have been fixed (based on the link you posted).
TOP!!!
EXCELLENT fix! I’ve been fighting with Visual Studio for three days trying every other solution. Yours worked PERFECTLY! Thank you so much!
Thanks a billion, it worked
