Unable to find Nuget package "entityframework"

Question

I am pretty new to EF and have tried to install entityframework from the Package Manager console. But I get this error:

PM> install-package entityframework
install-package : Unable to find package 'entityframework'.
At line:1 char:1
+ install-package entityframework
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Install-Package], InvalidOperationException
    + FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PowerShell.Commands.InstallPackageCommand

Not sure why I am getting this error.

This is my settings for Package Source;

Is the Package Source setup correctly, if it is, what is the issue with installing EF?

Please advise.

Can you install other packages? Also, can you install anything via the Manage NuGet packages... window (just right click on the project in Solution Explorer)? — Peter Szekeli

Doesn't matter, try NewtonSoft.Json. Just to see if the issue is with EF only or with the connection to NuGet in general. — Peter Szekeli

Try updating your NuGet package Manager (via Tools -> Extensions and updates and then add a new feed with https://api.nuget.org/v3/index.json as source.

UPDATE

NuGet Package Manager
Go to Tools -> Extensions and updates, in the popup, select the Updates -> Visual Studio Gallery submenu. Check if NuGet is listed there. If so, update it.

Adding a new NuGet feed
Go to Tools -> Options -> NuGet Package Manager -> Package sources. Click on the green plus icon to add a new source. You can enter any name you want (e.g. nuget.org) and enter https://api.nuget.org/v3/index.json as source.

After this is done, in Package Manager Console, you'll see the newly created entry in the dropdown Package source.

I apologize for my ignorance. Could you please elaborate what you meant by adding a new feed? Replacing the existing Package Sources with the url you mentioned above? I went in extensions and updates, and was told Nuget Package Manager already existed, I only have the option to remove it.

See me comment with the extended description.

Thanks Szeki. Adding the new feed in Tools->Option works! Thanks!

Simply restarting Visual Studio worked for me (for some reason).
