Nuget config and dnu restore on fresh windows install - nuget

After getting a new server up and running, I tried to get a dnx project working. I ran dnu restore on a project, and get this error.
Errors in C:\apps\ElasticIndexer\app\project.json
Unable to locate Dependency TestApplication >= 1.0.1
Feeds used:
https://api.nuget.org/v3-flatcontainer/
My issue is that I am unable to change the nuget feed used, as we host our nuget packages on a different server. I searched in %appdata% and there was no folder for nuget. I then decided I would do a search for nuget.config on the whole server and there was no nuget.config file.
I don't want to install Visual Studio on this server, but is there a reason why I don't have a nuget folder in my %appdata% folder? How does dnu know to search api.nuget.org by default? When installing latest dnvm is it supposed to create the nuget location as well, or do I need to manually create the folder and config file?

If there isn't a nuget.config file on your server you could try running nuget install. If that doesn't work try updating the sources via the command line:
NuGet.exe Sources Add -Name <feedName> -Source <pathToPackageSource>

NuGet CLI not restore the package for the packagereference

I have created a new .net core project with Visual Studio 2017, then add a nuget package Newtonsoft.Json to the project. After that I know the package will cached at the folder C:\Users\<UserName>\.nuget\packages.
For some reason, I have to delete it, then I want to restore it, but I could not restore it with nuget.exe. nuget.exe restore, command can be executed successfully, but the package is not downloaded to that folder.
I also have tried the command MSBuild /t:restore, but it still does not work, package not download.
Any suggestion?

Restoring NuGet packages

I have a C# solution containing several projects. Some of projects has referenced nuget packages. Whole solution (but no downloaded dlls) is tracked by git repository.
After cloning it to other place and trying to build nuget asks if it should download missing packages. After downloading there are still several referenced library missing.
I can fix it one by one doing following steps:
Remove reference
Remove package in packages.config file
Install this package again by nuget
Is there any better way to do this? I tried reinstalling all nuget packages, but my Visual Studion crashes. After restarting and retrying it left me with more missing packages.
Another way to do this is running:
PM> Uninstall-Package {Name}
PM> Install-Package {Name}
for each missing package. By missing package I mean all packages with yellow mark. I can't install it without uninstall command, becasue nuget says it is already referenced.
If you try running the following from the command line does it restore all the packages?
nuget.exe restore YourSolution.sln
If not then it sounds like there's some packages that are missing from your project's packages.config file.
You could try the updating the packages with the reinstall parameter from the PowerShell console.
Update-Package –reinstall <packageName>
You can also restrict this to one project if you want to by using the -ProjectName parameter.
This is probably because of the incorrect path of the .dll in your .csproj. The package restore downloads the packages to the local directory.
It doesn't change the reference path of the assembly in the .csproj, meaning that the project will still try to locate dlls on the local directory. The yellow mark means the project is unable to locate the assembly.
Unload the project, right click on project and select "Edit .csproj", and verify the path of missing dlls.
For example - If you have NUnit,
<Reference Include="nunit.framework">
<HintPath>..\packages\NUnit.3.6.1\lib\net45\nunit.framework.dll</HintPath>
</Reference>
verify if the dll is present inside "\packages\NUnit.3.6.1\lib\net45" directory.

how to get all nuget dependencies for offline installation

I two computers, one with internet connection and the other one without.
I want to install a Nuget package (Nuget.server) with all its dependencies on the offline computer.
Unfortunately it is not possible just to download the package itself and I have to download all dependencies manually and there are dozens of them.
How can I create a package on the computer with internet connection that contains all dependencies?
Thanks.
I just went through the pain of this and wanted to find a solution using only the NuGet CLI. Turns out it's pretty simple really:
> nuget.exe install <PACKAGENAME> -OutputDirectory <OUTPUTDIR>
The key is the -OutputDirectory switch which makes the CLI install the specified package into a directory that doesn't have a project file in it. Running this command will download the package and all of its dependencies into the output directory, with each package put into a separate sub-folder. You can then grab all of the .nupkg from the output directory and do whatever you need to do with them.
Update: As Igand points out in the comments, the -OutputDirectory switch is not actually required. If omitted nuget.exe will just download into the current folder. Still best to not download it into a folder with a project file in it (unless that is what you're after).
I had a similar need, so I created NuSave.
Cache a single NuGet package with dependencies
nusave cache package "Newtonsoft.Json#12.0.3" --targetFrameworks ".NETStandard#1.0,.NETStandard#1.3" --cacheDir "C:\path\to\my-local-feed"
Cache multiple NuGet packages from a .csproj file
nusave cache csproj "C:\path\to\project.csproj" --cacheDir "C:\path\to\my-local-feed"
Cache multiple NuGet packages from an .sln file
nusave cache sln "C:\path\to\solution.sln" --cacheDir "C:\path\to\my-local-feed"
Restore & build a solution offline using my local cache
cd C:\path\to\my-solution
dotnet restore --packages C:\path\to\my-local-feed
dotnet build --no-restore
On the computer with internet access the NuGet packages (.nupkg) should be in the local machine cache. On Windows this is in the directory similar to:
C:\Users\YourUsername\.nuget\packages
So you should be able to copy the .nupkg files from there to the computer without internet access. I would create a directory on that computer and setup a new package source pointing to that directory. Alternatively you could copy the .nupkg files to the local machine cache, just be aware there is a limit of 200 NuGet packages in the cache. Then you can create a package source pointing to the cache.
Use the dotnet restore command with the --packages flag, which will download the packages to a specified directory.
dotnet restore --packages <TargetDirectory> <ProjectPath>
Ref: dotnet restore
Specifies the directory for restored packages.
A little late to the discussion here but I just ran into the same issue. I work with a medium size software development shop that works offline. Many new NuGet packages have very large dependency trees. Trying to walk the tree manually and download all required packages was very cumbersome. In the end, I wrote the NuGet Dependency Downloader. With it you give a package ID, optionally a version, and choose if you want to allow pre-release packages. After you click "Start" it will pull down the listed package and any dependencies it needs to run. As an example, when I put in "Microsoft.AspNet.Mvc" and selected "pre-release", this tool brought down 158 packages for MVC 6.0 RC1. Hopefully this will help those working in an offline environment.
https://github.com/StuffOfInterest/NuGetDependencyDownloader
In your csproj file:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>
<PropertyGroup>
Or dotnet publish with all assemblies references.

How to update packages using Nuget.exe

For my little sample projects in .NET (built directly on the command line without employing Visual Studio) I want to use directly Nuget.exe to retrieve the libraries I need, without having to commit them in the source repository.
I've been able to install them using the command
nuget install packages.config -o $destinationFolder
specifying the needed packages in a packages.config (like Nuget in Visual Studio).
However, I'm unable to update installed packages. I've tried to use this command
nuget update packages.config -r $destinationFolder
but Nuget.exe complains that is
unable to locate project file for '...packages.config'`.
I've searched on the Internet but I only find a similar question in the Nuget discussion forums without answers.
I've read the relevant source files in the Nuget project and I've discovered that for the update to succeed Nuget.exe needs to find a Visual C#/Basic/F# project.
I then created an empty csproj file in the folder and I've been able to update the packages I've installed before.
I've made a small sample at https://github.com/edymtt/nugetstandalone that shows how to install and update packages with Nuget.exe. I've also used a workaround to make sure that only the latest versions of the libraries are kept in the folder.
Update 2013-04-06 14:20 UTC I've updated the sample to show how to achieve that using the -ExcludeVersion flag of the install command.

Download Nuget Packages Without VS/NuGet Package Manager

How can I download NuGet Packages outside of visual studio? so it can be used to create offline packages.
How to download NuGet Package without Visual Studio or Nuget Package Manager:
Search your desired package at NuGet Official Site.
Copy the end of the URL of the package page.
For Example: http://nuget.org/packages/EntityFramework => Package Name is "EntityFramework"
Enter the URL: http://packages.nuget.org/api/v1/package/{Package Name}
For Example: http://packages.nuget.org/api/v1/package/EntityFramework
You can download NuGet packages outside of Visual Studio using:
NuGet Package Explorer
NuGet Package Explorer is a ClickOnce application which allows
creating and exploring NuGet packages easily. After installing it, you
can double click on a .nupkg file to view the package content. You can
also load packages directly from the official NuGet feed.
Open a package from online feed:
And export the package to the desired location:
Install the NuGet command line program:
The NuGet command line may be installed onto a machine in a few possible ways.
Direct download of the executable from https://dist.nuget.org/win-x86-commandline/latest/nuget.exe. The executable may be placed anywhere on the file system, and in most cases should be placed in a directory that is listed in the PATH environment variable.
Install the NuGet.CommandLine package from the NuGet Visual Studio client and either move nuget.exe to a common location or execute it in the context of your project.
Install the NuGet.CommandLine Chocolatey package using the Chocolatey client. More information on Chocolatey can be found at [http://chocolatey.org].
Then run nuget install package to download and install package in the current directory.
More about the NuGet command line program:
Command Line Reference
Chrome Plugin "NuTake" provides a direct download link.
Rename extension to .zip and extract
You can download nuget packages using - vnuget.org.
On this website you can also view content of nuget package - http://vnuget.org/packages/Microsoft.AspNet.Mvc/5.2.3.
Here are a few examples that can add to DeePak's answer:
This one downloads AutoMapper from NuGet.org
nuget.exe install AutoMapper -OutputDirectory c:\Temp\LotsOfPackages -Version 6.2.2
This one downloads MyCustomPackage from an internal TFS Nuget feed
nuget.exe install MyCustomPackage -OutputDirectory c:\Temp\LotsOfPackages -Source "http://tfs.myCompany.com:8080/tfs/TFSArea/_packaging/FeedName/nuget/v3/index.json" -Version 1.0.0.2
Notes
Keep in mind that the install command will get the package in question AND all its NuGet dependencies. So, be careful about just dumping this into the directory where you running. Thus, I added OutputDirectory to the command.
For internal Nuget packages/feeds, the Source URL is available via TFS. Go to your packages tab and find your specific feed URL. If it has any spaces that have been encoded with %20, you need to replace them with spaces.
