Answer 1

I had problem with restoring package with error 401 unauthorised. I found the solution by unchecking available local package sources. Debug > Options > NuGet Package Manager > Package Sources

Only allow nuget.org packages

Answer 2

For others this option is available in the Nuget settings section in Visual Studio Options

As it turns out, the real solution is to migrate to Automatic Package Restore. We experienced issues with NuGet after upgrading to VS 2015 after working in 2013 for a while. Turns out the old way of doing NuGet completely hoses the new way of doing it.

The solution is simple, though tedious. Apparently the NuGet.targets file signals VS to use the old NuGet way of doing things, and it's absence means that you are now using "Automatic Package Restore". You can migrate to Automatic Package Restore by following these steps:

1. Delete .nuget/NuGet.exe
2. Delete .nuget/NuGet.targets
3. For each project:
   1. Unload the project
   2. Right click -> Edit the project
   3. Delete all references to the NuGet.targets file, i.e. the following:

<RestorePackages>true</RestorePackages>  
...
<Import Project="$(SolutionDir)\.nuget\nuget.targets" />  
...
<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">  
    <PropertyGroup>
        <ErrorText>This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>
    </PropertyGroup>
    <Error Condition="!Exists('$(SolutionDir)\.nuget\NuGet.targets')" Text="$([System.String]::Format('$(ErrorText)', '$(SolutionDir)\.nuget\NuGet.targets'))" />
</Target>

There is also a powershell script that will perform the migration for you, if you are feeling bold. You can find it on github.

Well it is pretty simple with VS2015, all i had to do was to right click on my project solution and click on restore nuget.

Answer 5

My Visual Studio 2015 Professional was installed using the default settings. The options for "Allow NuGet to download missing packages" and "Automatically check for missing packages during build in Visual Studio" were already checked by default, but I still could not download the packages. I was getting an error that a package version could not be found.

I needed to click a checkbox under Tools > Options > NuGet Package Manager > Package Sources to enable NuGet Package Restore to work as expected.

I had the same problem as you and the way I solved it was to delete the packages folder from my solution and also bin and obj folders from every project in the solution and give it a rebuild.
