How do I enable NuGet Package Restore in Visual Studio

Question

There s a similar post on stack but it doesn t help with my issue possibly because I am using Visual Studio 2015   How do I get the  Enable NuGet Package Restore  option to appear in VS2015   I chose File   New Project and created an empty ASP NET Web Application  I m looking for this menu option     I should mention that I have looked for any pre-existing nuGet files in my project folder and there are none

If all else fails  or perhaps before then  you may want to check and see if NuGet is a package source   I installed VS2017  and it was NOT there by default   I thought it was kind of odd    Tools - NuGet Package Manager - Package Manager Settings Click  Package Sources  on left nav of dialog  Use plus sign     to add Nuget URL   https   api nuget org v3 index json

Use this command to restore all packages  dotnet restore

Could also be a result of running the program while you re trying to install the package  it s grayed out if you try to click it while the built in IIS is running in the background

This approach worked for me     Close VS2015 Open the solution temporarily in VS2013 and enable nuget package restore by right clicking on the solution  i also did a rebuild  but I suspect that is not needed    Close VS2013 Reopen the solution in VS2015   You have now enabled nuget package restore in VS2015 as well

As already mentioned by Mike  there is no option  Enable NuGet Package Restore  in VS2015  You ll have to invoke the restore process manually  A nice way - without messing with files and directories - is using the NuGet Package Management Console  Click into the  Quick start  field  usually in the upper right corner   enter console  open the management console  and enter command   Update-Package    reinstall   This will re-install all packages of all projects in your solution  To specify a single project  enter   Update-Package    reinstall -ProjectName MyProject   Of course this is only necessary when the Restore button - sometimes offered by VS2015 - is not available  More useful update commands are listed and explained here  https   docs microsoft com en-us nuget consume-packages reinstalling-and-updating-packages

Ivan Branets  s solution is essentially what fixed this for me  but some more details could be shared   In my case  I was in VS 2015 using Auto Package restore and TFS   This is all pretty default stuff   The problem was that when another developer tried to get a solution from TFS  some packages were not fully getting restored    Why  that I m not quite sure yet    But the packages folder contained a folder for the reference and the NuGet package  but it wasn t getting expanded  say a lib folder containing a  dll was missing    This half there  but not really quite right concept was preventing the package from being restored   You ll recognize this because the reference will have a yellow exclamation point about not being resolved   So  the solution of deleting the folder within packages removes the package restore blocking issue  Then you can right click at the top solution level to get the option to restore packages  and now it should work

In case anyone else finds this problem in Visual Studio 2017  make sure the project is opened by the  sln file and not the folder  as visual studio won t pick up the settings if it s opened by folder  This happens by default if you re using Visual Studio online services for git

If you have any problems or are missing any packages you can simply right-click in your project and select  Manage NuGet Packages for Solution      After clicking on this a screen will open where you see a menu bar saying  Restore     Click on it and the required packages will be installed automatically  I believe this is what you re looking for  this solved my problems

Microsoft has dropped support for the  Enable NuGet Package Restore  in VS2015 and you need to do some manual changes to either migrate old solutions or add the feature to new solutions   The new feature is described pretty well in NuGet Package Restore  There is also a migration guide for existing projects  as previously mentioned  here  NuGet Migration Guide When upgrading   do not delete the  nuget directory  Delete the nuget exe and nuget targets files  Leave the nuget config  Purge each of the project files of any reference to the NuGet targets by hand   The Powershell script mentioned seemed to do more damage than good   When creating a new project   In your Visual Studio 2015 solution  create a Solution Directory called  nuget   Create an actual directory of the solution directory  where the  sln file lives  and call it  nuget  note that the solution directory is not the same as the actual file system directory even though they have the same name    Create a file in the  nuget directory called nuget config   Add the  nuget config  to the solution directory created in step  2   Place the following text in the nuget config file    lt  xml version  quot 1 0 quot  encoding  quot utf-8 quot   gt    lt configuration gt     lt config gt       lt add key  quot repositorypath quot  value  quot               Packages quot    gt     lt  config gt     lt solution gt       lt add key  quot disableSourceControlIntegration quot  value  quot true quot    gt     lt  solution gt   lt  configuration gt      This configuration file will allow you to consolidate all your packages in a single place so you don t have 20 different copies of the same package floating around on your file system   The relative path will change depending on your solution directory architecture but it should point to a directory common to all your solutions  You need to restart visual studio after doing step 5  Nuget won t recognize the changes until you do so  Finally  you may have to use the  Nuget Package Manager for Solutions  to uninstall and then re-install the packages   I don t know if this was a side-effect of the Powershell script I ran or just a method to kick NuGet back into gear   Once I did all these steps  my complicated build architecture worked flawlessly at bringing down new packages when I checked projects out of TFVC
