I know this is an old post  but thought this could be useful   If you have a need to ignore specific packages during the update process  like any packages that update JavaScript references   use the following PowerShell script  make sure your package source is set to  All  in Package Manager Console    EDIT 2014-09-25 10 55 AM EST - Fixed a bug in the script   packagePath    packages config   projectName    MyProjectName    packagesToIgnore           bootstrap        jQuery        jquery-globalize        jquery mobile        jQuery jqGrid        jQuery UI Combined        jQuery Validation        Microsoft jQuery Unobtrusive Validation        Modernizr        Moment js      xml  packageFile   gc  packagePath  packagesToProcess    packageFile packages package   Where-Object   packagesToIgnore -notcontains    id    packagesToProcess       Update-Package -reinstall -projectname  projectName -id      id

There is another  newer and quicker way to do this from within Visual Studio   Check out  this post by David Ebbo  and reference the comments section if you run into trouble   Basically  you do the following in Package Manager prompt   PM gt  Install-Package NuGetPowerTools PM gt  Enable-PackageRestore   Afterwards  when you build your solution the packages will be automatically installed if they re missing   Update   This functionality is built into Nuget 1 6 with visual studio integration so you don t even need to install NuGetPowerTools or type commands   All you have to do is      Right click on the Solution node in Solution Explorer and select   Enable NuGet Package Restore    Read this article for more details

I m using visual studio 2015 and the solutions given above didn t work for me  so i did the following   Delete the packages folder from my solution and also bin and obj folders from every project in the solution and give it a rebuild   Maybe you will have the next error       unable to locate nuget exe   To solve this  Change this line in your NuGet targets file and setting it to true    lt DownloadNuGetExe Condition      DownloadNuGetExe           gt true lt  DownloadNuGetExe gt    Reference https   stackoverflow com a 30918648 and https   stackoverflow com a 20502049

For those arriving here due to the build server falling foul of this  you can create an MSBuild target running the exec command to run the nuget restore command  as below  in this case nuget exe is in the  nuget folder  rather than on the path   which can then be run in a TeamCity build step immediately prior to building the solution   lt Target Name  BeforeBuild  gt     lt Exec Command      nuget nuget restore    MySolution sln   gt   lt  Target gt

I believe the first thing you need to do is enable the package restore feature   See also here   This is done at the solution  not project  level   But that won t get you all the way -- I ran into a similar issue after having enabled the restore feature    VS2013  NuGet 2 8    It turned out I had  unintentionally  committed the packages to source control when I committed the project -- but Visual Studio  and the source control plugin  had helpfully ignored the binaries when performing the check-in   The problem arose when I created a release branch   My local copy of the dev main trunk branch had the binaries  because that s where I had originally installed downloaded the packages  However  in the new release branch    the package folders and  nupkg files were all there -- so NuGet didn t think there was anything to restore  but at the same time  none of the DLLs were present -- i e  the third-party references were missing -- so I couldn t build    I deleted all the package folders in   SolutionDir  packages  under the release branch  and then ran a full rebuild  and this time the build succeeded      and then of course I went back and removed the package folders from source control  in the trunk and release branch    I m not clear  yet  on whether the repositories config file should be removed as well   Many of the components installed for you by the project templates -- at least for web projects -- are NuGet packages  That is  this issue is not limited to packages you ve added  So enable package restore immediately after creating the project solution  and before you perform an initial check-in  clear the packages folder  and make sure you commit the  nuget folder to source control    Disclaimer  I saw another answer here on SO which indicated that clearing the packages folder was part of the resolution   That put me on the right track  so I d like to give the author credit  but I can no longer locate that question answer   I ll post an edit if I stumble across  it   I d also note that Update-Package -reinstall will modify the  sln and   csproj  vbproj files   At least that s what it did in my case   Which IMHO makes this option much less attractive

You can use nuget exe to restore your packages or with NuGet 2 7  or above  installed you can simply compile your solution in Visual Studio  which will also restore the missing packages   For NuGet exe you can run the following command for each project   nuget install packages config   Or with NuGet 2 7 you can restore all packages in the solution using the command line   nuget restore YourSolution sln   Both of these will pull down the packages  Your project files will not be modified however when running this command so the project should already have a reference to the NuGet packages  If this is not the case then you can use Visual Studio to install the packages   With NuGet 2 7  and above  Visual Studio will automatically restore missing NuGet packages when you build your solution so there is no need to use NuGet exe   To update all the packages in your solution  first restore them  and then you can either use NuGet exe to update the packages or from within Visual Studio you can update the packages from the Package Manager Console window  or finally you can use the Manage Packages dialog   From the command line you can update packages in the solution to the latest version available from nuget org   nuget update YourSolution sln   Note that this will not run any PowerShell scripts in any NuGet packages   From within Visual Studio you can use the Package Manager Console to also update the packages  This has the benefit that any PowerShell scripts will be run as part of the update where as using NuGet exe will not run them  The following command will update all packages in every project to the latest version available from nuget org   Update-Package   You can also restrict this down to one project   Update-Package -Project YourProjectName   If you want to reinstall the packages to the same versions as were previously installed then you can use the -reinstall argument with Update-Package command   Update-Package -reinstall   You can also restrict this down to one project   Update-Package -reinstall -Project YourProjectName   The -reinstall option will first uninstall and then install the package back again into a project   Or  you can update the packages using the Manage Packages dialog   Updates    2013 07 10 - Updated with information about nuget restore in NuGet 2 7 2014 07 06 - Updated with information about automatic package restore in Visual Studio and brought the answer up to date with other changes to NuGet  2014 11 21 - Updated with information about -reinstall

In Visual Studio 2017 - When you compile using IDE - It will download all the missing nuget packages and save in the folder  packages    But on the build machine compilation was done using msbuild exe  In that case  I downloaded nuget exe    During each build process before executing msbuild exe  It will execute -  nuget exe restore NAME OF SLN File  if there is only one  SLN file then you can ignore that parameter
