I get a message saying the following:
Error 1 Package restore is disabled by default. To give consent, open
the Visual Studio Options dialog, click on Package Manager node and
check 'Allow NuGet to download missing packages during build.' You can
also give consent by setting the environment variable
'EnableNuGetPackageRestore' to 'true'.
When I go to Tools -> Options, I do not see Package Manager and underneath I see Package Sources and Recent Packages. I do not see anywhere where I can set Allow Nuget to download missing packages during build though.
The option to give consent in the UI has been added with NuGet Package Manager 1.8. It's the 3rd item under Tools-> Options-> Package Manager-> General : "Package Restore : Allow NuGet to download missing packages during build".
Please make sure NuGet is up-to-date in Tools->Extension Manager.
Alternatively you can give consent by setting the EnableNuGetPackageRestore Environment variable to true.
I found I needed an extra couple of steps to get it to download the packages
Check Allow NuGet to download missing packages during build
Check Always show solution in Projects and Solutions
Right click on solution and Enable NuGet Package Restore
Open Manage NuGet Packages and click Restore
I did not seem to have the "Package Manager" node under Tools->Options [this was in Visual Studio 2013 :-)]. To get that node in there, I browsed to Tools -> Extensions and Updates and searched for nuget. Installing "NuGet for Visual Studio 2013" got me the node and the option to allow package restore!
I am using Visual Studio 2010 and NuGet 2.0.
Someone had checked in a solution that used NuGet for various packages. When I checked out the solution and built it, I got the same errors. What's more, when I viewed the NuGet Package Manager from the Tools -> Options window, the Package Restore already had the appropriate check boxes checked.
I tried clicking the Clear Package Cache button. After doing that, everything built correctly.

Does NuGet support global package installation like NPM and Composer? If so, how do I do that? Also, how do I reference globally installed packages in my Visual Studio projects?
So learning from #Lance's tips, I went ahead and checked %userprofile%\.nuget\packages folder, and indeed it contains all the packages that I have downloaded in the past. Unfortunately though, Visual Studio (I'm using Community 2019) does not allow you to install any of these packages into a new project. The Browse page in NuGet Package Manager UI displays online results only from nuget.org.
But then I found another clue. In Visual Studio Tools > Options > NuGet Package Manager > Package Sources, you can add custom sources. So I went ahead and added my cache folder as an alternate source.
Note that there is a separate "Machine-wide package sources" entry too that cannot be modified. I checked that folder and it contains mostly Microsoft's own packages (one exception that I found there was NewtonSoft.json). I have no idea how this folder is different from the nuget cache folder and how I can download a package to this folder.
So far so good. The Package Manager now shows all previously downloaded packages from cache when I select this source from the drop down (sources dropdown is in top-right corner). I can then select a package and install it from local source instead of downloading it from the Internet.
Hope this helps someone down the line.
I know there's an answer for this question from 2016 but it's not working today. I have VS2013 with the latest CU installed.
My Nuget package source settings:
I want to install the nu-get package "Serilog.Sinks.MSSqlServer". First, I ensure nuget is up to date by navigating to the ".nuget" folder of the solution's folder and running "nuget update -self":
Unfortunately, I still get the error when trying to add the package:
If I try to update nuget from the "Extensions and Updates" page of VS then I get a 403 error as shown below:
The 403 does suggest a proxy issue but other packages can be installed to the same dev box ok. I just installed "Apache log4net" from the Manage NuGet Packages window - no problem
Any ideas of a work-around for this please?
This might be related to the fact that you now (with the new NuGet CLI tool version) need to use the new NuGet API.
from nuget.org
NuGet feed v3 (VS 2015 and later / NuGet v3.x and above): https://api.nuget.org/v3/index.json
NuGet feed v2 (VS 2013 and earlier / NuGet 2.x): https://www.nuget.org/api/v2
You can check (and edit) your NuGet Package Sources under Tools, Options, NuGet Package Manager, Package Sources.
#Rob Bowman, in response to your comment and looking at the screenshot of your Available package sources, try edit your default nuget.org to https://api.nuget.org/v3/index.json or add a new source and make sure they're both enabled. Maybe that'll do the trick.
Update: maybe manually updating the NuGet Package Manager (since updating it through Extensions and Updates is not working) solves the problem. NuGet Package Manager for Visual Studio 2013.
Going to Visual Studio menu Help, About should display the currently installed version of this extension (and others).
To fix this I had to:
logon to a PC not connected to the corporate proxy
download the latest version of the nuget package manager (VSIX) for VS2013 from https://marketplace.visualstudio.com/items?itemName=NuGetTeam.NuGetPackageManagerforVisualStudio2013
copy the VSIX to my corporate dev VM and install
I just built a new PC, installed my dev tools, connected to TFS and downloaded my project. Now most of my references are broken to EF, jQuery, etc.
The packages folder is missing all the .dlls, if I try to use NuGet restore nothing happens. If I use NuGet manager for Solution there is no "force" reinstall option.
NuGet seems to be more a hindrance than a help.
You can run "Update-Package -reinstall" command from Package Manager Console in VS to force reinstall all the packages.
Package authors often need to reinstall the same version of package
they are developing to test the behavior. The command Install-Package
does not provide ‘-force’ option, that could forcefully reinstall a
package. So, Update-Package -reinstall is added to meet that
requirement.
I've had that same issue plenty of times when I need to re-download code after getting a new PC. Here's what worked for me:
Download the project from TFS (or in your case SVN).
Delete the "packages" folder
Make sure the "Package Manager Console" is enabled (Tools -> NuGet Package Manager -> Package Manager Console)
Open the solution file.
At the right side of the "Package Manager Console," a "Restore" button should appear. Click on the "Restore" button.
Hope that helps you.
I'm not sure if I'm supposed to share the link if I already answered a similar question or just answer again, so I'm doing both. Here's the link to the same answer from a different asker.
Edit:
If after you complete the above steps you are still getting syntax errors from missing references, right-click on References in the Solution Explorer and then just hit OK. That fixed the problem with the references for me.
I've installed Nuget Package Manager for Visual Studio 2015, yet when i try to install most packages I am met with the following error. Any ideas what this issue is would be greatly appreciated...
Your package source, in the drop down at the top left of the Package Manager Console, is currently set to Microsoft and .NET. If you change it to be nuget.org then it should work.
The Microsoft and .NET package source contains the NuGet packages that Microsoft supports which is subset of the packages available from nuget.org.
In Visual Studio go to the Tools -> Options menu, expand NuGet Package Manager, and then click on Package Sources. Ensure "Microsoft and .NET" is checked in the Machine-wide Package list.
When you next start the Package Manager make sure the Package Source dropdown at the top-right has a value selected.
I accidently added a package to my VS2010 MVC 3 project via the 'Manage NuGet Packages' tool in the 'Tools' menu and I would like to remove it, however after some research I can't seem to figure out how to do it.
I have tried opening up the 'Manage NuGet Packages' tool within the solution, but there seems to be no uninstall option so I searched online and found the following article on installing and uninstalling packages. It mentions right clicking on the project and choosing the 'Add Package Library Reference' option, but this doesn't exist. I did notice that the example's project is a Website type, where mine isn't as I am using a modified version of the MVC project template.
Anyway, I searched online again and found several mentions of starting VS2010 as an Administrator and then the option for uninstalling should be available in the 'Manage NuGet Packages' tool, however this didn't change anything and no uninstall option appears.
Can anyone suggest what might be the problem and how to remove this package?
Here's a link to the docs:
Go to the section entitled Removing a Package, you can use the console to uninstall the package you want.
From the Library Package Manager, click the Installed Packages tab, then click Manage on the package you want to remove. Clear the checkbox for the solution/project you want the package uninstalled from, then click OK.
Or, open up the Package Manager Console and type "uninstall-package YourPackageName".
