What is required to run NuGet?
NuGet requires Visual Studio 2010 Pro/Premium/Ultimate (or newer), Visual Web Developer Express 2010, or any Express SKU of Visual Studio 2012 (or newer). The NuGet Package Manager Console requires that PowerShell 2.0 be installed. Powershell 2.0 is already installed if you have the following operating systems:
If you have the following operating systems, you must manually install Powershell 2.0.
Do I have to install ASP.NET MVC to get NuGet?
Not at all. For information about how to install NuGet without MVC , see Installing NuGet.
Does NuGet support Mono?
The command-line application (nuget.exe) builds and runs under Mono (version 3.2 or later) and allows you to create packages in Mono. This is especially true for Mono on Windows, but there are some known issues for Mono on Linux and OS X. To review the known issues, search for Mono in our issue list.
Is there a command-line tool for NuGet?
Yes there is! See David Ebbo's Blog post entitled Installing NuGet Packages directly from the command line.
Keep in mind that the focus of NuGet is to let you modify your projects and add references to Visual Studio projects. The command line tool, NuGet.exe, will download and unpack packages, but it won't automate Visual Studio and modify your project files. Within Visual Studio, there are two clients for NuGet: the PowerShell-based Package Manager Console and the Manage NuGet Packages dialog box. Both are wrappers around the NuGet API, which is written in managed code. NuGet.exe is also used to create and publish packages.
How do I check the exact version of NuGet installed?
In Visual Studio go to the Help > About Microsoft Visual Studio menu and look for NuGet Package Manager. The version is displayed next to that entry.
Alternatively, you can launch the Package Manager Console and type in
$host to output information about NuGet
Powershell host including the version.
What languages are supported by NuGet?
What project templates are supported by NuGet?
NuGet has full support for a variety of project templates like Windows, Web, Silverlight, SharePoint, Wix and so on. The support for LightSwitch and Cloud templates is minimal at this point of time.
How do I update packages that are part of visual studio templates ?
You can do an "Update All" from the "Manage NuGet Packages" dialog. More details here or use the "Update-Package" command from NuGet Package Manager Console. This will get the latest version of all the packages that are part of the template.
However, if you want to update the template in one go, instead of doing it for every project, you will have to manually update the template repository. Check out Xavier Decoster's blog on the same.
Please be noted that manually updating the template repository should be done at your own risk. It might corrupt the template files or the latest version of the packages may not be compatible with each other.
You sure can! As discussed in the question on command line tools for NuGet, the primary focus of NuGet is Visual Studio, but the core NuGet API has no dependencies on Visual Studio. There are multiple NuGet clients that work completely outside of Visual Studio:
How do I get the latest version of NuGet commandline?
Once you have the command-line, use "NuGet.exe Update" to self update the exe to the latest version.
Is it possible to extend NuGet commandline?
Yes, it is possible to add custom commands to NuGet.exe. Check out this post by Rob Reynolds for a quick walkthrough.
How do I get access to the DTE object in the Package Manager console?
The console provides a variable named
$DTE that returns the
DTE object. See the
Get-Project command in
Package Manager Console Powershell Reference.
Why does the Package Manager Console or the Manage NuGet Packages dialog box crash or show an exception?
Check the Known Issues page. Typically, the issue is due to having an older version of the Reflector add-in installed or not having PowerShell 2.0 installed (as in the case of Windows XP).
I try to cast the $DTE variable to the type DTE2, but I get an error: Cannot convert the "EnvDTE.DTEClass" value of type "EnvDTE.DTEClass" to type "EnvDTE80.DTE2". What's wrong?
This is a known issue with how PowerShell interacts with a COM object. Try the following:
$dte2 = Get-Interface $dte ([EnvDTE80.DTE2])
Get-Interface is a helper function added by the NuGet PowerShell host.
How do I get my package in the feed?
See the Creating and publishing a package page.
I have multiple versions of my library that target different versions of the .NET Framework. How do I build a single package that supports this?
See the section titled "Supporting Multiple .NET Framework Versions and Profiles" in Creating a Package.
How do I set up a local repository or feed?
How can I bulk upload packages to my NuGet feed ?
How can I create package out of a project or solution ?
You can use Nuget.exe Pack command to create a NuGet package out a project.
This command will take care adding all the NuGet packages installed in the project as package dependencies and referenced projects as "Reference" assemblies in the package. You can invoke this command in post build event to automate the build process.
What is the difference between a project-level package and a solution-level package?
A solution-level package has to be installed only once in a solution to be available for all projects in the solution. A project-level package must be installed separately in each project where you want to use it. For solution-level packages, NuGet doesn't change anything in a project, whereas in a project-level package it does. Typically, a solution-level package installs new commands that can be called from within the Package Manager Console window.
Is it possible to install NuGet package without internet ?
Yes you can! See Scott Hanselman's Blog post entitled How to access NuGet when NuGet.org is down (or you're on a plane).
How to install packages in a different location from the default "Packages" folder?
This can be done by setting the "repositoryPath" settings in nuget.config. More details here.
How do I avoid checking in packages folder to source control?
You can turn off source control integration for the Packages folder by setting the "disableSourceControlIntegration" propety in the nuget.config to "true".
This key works at the solution level and hence need to be added to the NuGet.config file present in the "$(SolutionDir).nuget directory". Enabling package restore from VS would add the .nuget\nuget.config file automatically.
How do I turn off package restore?
You can disable package restore at the machine wide using the package manager settings or by setting an environment variable "EnableNugetPackageRestore" to "false". However, to disable just at sln level, you would have to manually delete the .nuget folder from the Solution and the file system and revert the changes in the csproj file related to package restore.
Why do I get an "Unable to resolve dependency error" when installing a local package with remote dependencies?
Select the All node when installing your local package. The all* node aggregates all the feeds. When you select a specific repository under the Online tab, that restricts installation to just that node. The reason for this behavior is that in many cases, users of a local repository don't want to accidentally install a remote package due to corporate polices.
Is it possible to reserve names for packages that will be published in future?
It is not possible to squat package names. If you feel that an existing package has taken the name which suits your package more, try [contacting the owner of the package](https://nuget.org/packages/[package ID]/ContactOwners?). If you didnt get response within a couple of weeks, you can contact support and the NuGet Gallery team will look in to it.
How do I claim ownership for packages ?
Check out the blog post Managing Package Owners on nuget.org for details.
Is it recommended to upload my test packages to NuGet.org ?
