According to this question:
using nuget.exe commandline to install dependency
The command line NuGet tool does not follow dependencies intentionally. While I could understand this as the default behavior, it seems odd to me that there is no choice to have the tool follow the dependencies. Is anyone aware of the reasoning behind this?
That answer is specific to running nuget install packages.config.
When specifying packages.config, only explicitly listed packages are installed.
However, if you try installing a specific package: nuget install My.Package.Id then NuGet will install the package and any dependencies.
EDIT Additional info as to why there's a distinction.
nuget install should really be called nuget download. It doesn't really install in the traditional sense. That is, it doesn't add references to your project files, it doesn't run install.ps1, it doesn't update packages.config, etc. You need to either use the NuGet GUI or Package Manager console to get a true install.
Since the true install updates packages.config, this file already includes all the dependencies that were installed. So specifying the file means, I want to download these specific packages. NuGet doesn't need to think about it since it's basically pre-calculated.
If you want to install/download multiple packages and have NuGet follow dependencies, just create a batch file and issue multiple commands:
nuget install My.Package.Id
nuget install Another.Package.Id
This will cause NuGet to fetch the package an any dependencies it may have.
Hope this clarifies things.

I have a Visual Studio, C# solution with several projects. Some of those point to older versions of some packages. my local nuget repo has more current, stable versions. e.g.
What I want to do is update all those old 3.0.246-alpha references to the latest stable version, 3.1.0
What is the best way to do that?
Output window after clicking Install:
errors at top of screen:
This is what I want to fix. There is no version 3.0.246 of that module, so I want Nuget to overide it with latest stable version, 3.1
Due to the limitation, I post this as an answer, but may include some comments.(Sorry for that)
As I searched online(nuget.org), I found no packages called TBSM.*, perhaps they were created by yourself/your company… and just used(saved) locally?
From the error message, it reported that the NuGet package was not found on source XXXXX, so did you perform some operations to remove the old version of the NuGet packages? (Maybe also removed the NuGet cache files?)
I did some tests:
Since I don’t know the specific structures of your projects/NuGet Package, I just created two NuGet packages for test locally with same names(ID) and different versions, and then added the package source path to the settings, and installed the first NuGet package into one project, after that deleted this NuGet package and the cache files. Then tried to Update it, NuGet Package manager could still update it to the latest version successfully, even if I uncheck these options: Allow NuGet to download missing packages and Automatically check for missing packages during build in Visual Studio from VS > Tools > Options > NuGet Package Manager > General.
Of course, I may not remove all of the NuGet packages’ cache files, or the issue is cause by the specific NuGet packages’ structures(cause I used two NuGet packages, but yours maybe used the same one with something updated)…
What I suggest:
1). If it is possible, you can have a try Uninstall and then Install the relates version.(remember to make a backup before this)
2). Try to select this two options in VS(Tools > Options > NuGet Package Manager > General), “Allow NuGet to download missing packages” and “Automatically check for missing packages during build in Visual Studio”, and then click Clear All NuGet Cache(s) button. Make sure you have added the right path source from VS > Tools > Options > NuGet Package Manager > Package Sources and try to install/update the NuGet packages again.(Generally, clear cache will not cause errors, but please remember to make a backup before clearing cache)
I setup an internal NuGet server to host internal dll packages. The setup went smoothly. The spec and nupkg were created successfully. However, when I launch a test project and attempt to install it from Manage NuGet Packages it fails.
The internal package shows up under Manage NuGet Packages with an install button. I hit install but it does nothing. I check my references folder and saw nothing added.
If I check the Manage NuGet Packages at solution level, it has a green check mark indicate that it's installed but doesn't give me a Manage option to see which project it was installed to.
My issue is somewhat similar to this post below. The only difference is that I don't have sub folders for my library. I just have 1 dll and I'm putting the nupkg file directly under the Packages folder.
NuGet package fails to install
I'm not sure what I did wrong. Any suggestions?
Thanks to #MattWard for mentioned that the package got installed at the solution level. I went back to the official documentation here: https://docs.nuget.org/create/creating-and-publishing-a-package to review the differences with creating solution level package vs project level package and most important of all is the nuget naming convention when creating packages (the lib, content, etc. folder). I re-package my dll again with the naming convention and it works!
I am running a private Nuget Server locally on IIS.
I am creating packages and uploading them all via commadline using nuget.exe (Later on I have to put this on build server, hence the command line). However there is one issue I am stuck at.
I am trying to declare dependencies. I generate the nuspec file in the folder where the .csproj file is there. Then I manually edit the nuspec file to add this under the metadata tag:
<metadata>
<dependencies>
<group targetFramework=".NETFramework4.5">
<dependency id="DemoProject" version="2.0.0.0" />
</group>
</dependencies>
</metadata>
DemoProject, version 2.0.0.0 is present on the Nuget Server.
The project I am creating package for, MyProj.csproj does not have the reference to the DemoProject added to it via Visual Studio. It is just at the packing time I want to create the dependency. It sounds strange but is needed for some initial validation.
Then I run pack command:
"C:\nuget\NuGet.exe" pack MyProj.csproj -IncludeReferencedProjects -Prop Configuration=Release
Then I push it to NuGet server using command line.
When I do an install via command line, then only MyProj package is present at the install location.
When I use Nuget Package Explorer and create a package, I can use the Package Dependency Editor to specify the dependency. It asks for the URL of my local Nuget Server and then adds the dependency. And when I install that package, it works !!
There seem to be no difference in the generated nuspec file in both the cases.
Obviously Nuget Package manager is doing something which I am missing out on.
Any hints?
More details: When I create a lib folder in the Package manager console and put my dll manually, lib->net45->MyProj.dll, then when I install the package thus created also "does not" install the dependency. Back to reading documentation again.
I know this doesn't directly answer your question but I had an issue with NuGet dependencies and my solution may possibly provide a hint.
DLL#1 was had no NuGet Dependencies. Pushed that to my private repo.
DLL#2 referenced DLL#1 NuGet package. Pushed that to my private repo.
All fine and dandy except from the Application project when I go to "Manage NuGet Packages...", the NuGet Package for DLL#2 is listed on the Browse tab but it shows no dependencies. I was forced to install both DLL#1 AND DLL#2 nuget packages. I desired to install DLL#2 nuget package and get DLL#1 automatically.
The way I fixed this was uninstalling all NuGet packages from DLL#2 solution.
Then going to Tools > Options > NuGet Package Manager > General. Then set the Default package management format to Packages.config and then unchecking the option "Allow format selection on first package install".
Then i installed all the needed NuGet packages. Now when i pack it up and push it up to the server, it shows the proper dependencies when going to "Manage NuGet Packages...".
nuget pack doesn't see the dependencies because its looking for them in the \packages folder. That folder didn't exist because I was using PackageReference for package management.
All worked after switching to Packages.config for package management.
I know the problem I had wasn't the same as yours but if you're not using Packages.config for package management, perhaps its related.
Late answer but the issue with this nuspec is <group targetFramework=".NETFramework4.5">. I feel confident that ".NETFramework4.5" is an invalid targetFramework. A full list of the available Target Frameworks is here.
When working with the Dependency section, you may not need to use the group tag. Any users who encounter similar errors would do well to read through that section. They have samples of proper usage.
I'm trying to use nuget.exe outside of Visual Studio as part of our build infrastructure. The idea is that the various build tools are fetched by a bootstrapper script that initializes a working copy. The bootstrapper does this by using a file that specifies the required tools and their version.
Broken approach 1 - use manually edited packages.config
At first, it seemed like a good idea to keep a manually edited packages.config file and use nuget restore to install them during bootstrapping. However, this does not work for tools that have dependencies, unless I list every single dependency in the packages.config as well, a much to arduous approach to be feasible, because I found no easy way to recursively find all dependencies of a package.
See also using nuget.exe commandline to install dependency .
Broken approach 2 - use nuget install to update packages.config
The second idea was then to use nuget install to install the packages, and let that command update the packages.config, very similar to the Install-Package cmdlet in the package manager console. But, surprisingly, nuget install does not support this! It either takes a packages.config or a package ID as parameter, but I found no way to update the packages.config with the new package and its dependencies.
This problem can also be found in another (two year old) SO question, see nuget.exe install not updating packages.config (or .csproj)?.
Is there a working (and non-hacky) approach at all?
This must be a problem that many people face when using nuget outside of VS, so what is the best approach in that case?
Of course, I could just parse the packages.config and emit a nuget install for each package, but I really don't want to re-invent the dependency management part of nuget, this is what I'm using nuget for in the first place. So I'm left with the feeling that either an -WithDependencies switch on nuget restore or an -UpdatePackagesConfig switch on nuget install is missing...
Note that there are other SO questions regarding the broken approaches described above. What I'd like to know it what the best approach is to solve the root problem, i.e. manage packages with dependencies outside of VS.
nuget install does not currently make changes to the project file.
nuget install can be used to either restore the NuGet packages listed in a packages.config file or download and extract them.
If you do not need the project being modified then your solution of reading the packages in the packages.config file and calling nuget install seems like a reasonable approach.
If you need the project to be modified then you could look at one of the following:
Ripple - a command line tool that adds extra features to NuGet. It has a ripple install command line which is similar to nuget install but it also updates the project file. It has a lot of other features for supporting build servers so this might be a good fit.
NuGet packages outside of Visual Studio with SharpDevelop - this was an experiment I put together to see whether full NuGet support could be achieved, including PowerShell scripts, from the command line without using Visual Studio. It uses PowerShell and quite a bit of SharpDevelop.
Customise NuGet.exe to do what you need. nuget update, for example, does modify the project file, at least for file references, but will not run PowerShell scripts. So you could take the NuGet.exe source code and extend it.
Of the above only 3) would give you exactly what you need. The other two would require a bit of work to read the packages from the packages.config file or some other list and then install them.
See my answer to Why does the nuget command line tool not follow dependencies?
nuget install My.Package.Id will follow dependencies. However, if you want to install multiple packages, you will need to create a batch file with a separate nuget install command for each package. These are top-level packages. You don't need to "install" the dependencies, as they will get downloaded automatically.
If you ultimately want a packages.config file, I imagine you can generate one by enumerating all the packages that were downloaded. However, you would have to take care not to include multiple versions of the same package.
I believe that how nuget 3 works with project.json files may do what you are looking for. Essentially my understanding is that the unit of dependency becomes the package and not necessarily individual assemblies. From what I recall, the idea is the have only one place to manage these types of package references which the project (IDE/Editor), package manager, and other command line tools can use.
What I don't understand and feel somewhat frustrated about is that it appears that the project.json concept is being canceled. I don't know if plans are to reintroduce it at anytime in the future. In the mean time I keep on hearing updated info on tooling that takes advantage of project.json such as nuget so where you can actually rely on this is something that is unclear to me at this point.
I have created versions of NuGet packages,uploaded and it is working fine.
I have set of libraries in my package which has been populated in different directories inside the package.
Some users might require a particular directory of my NuGet package, and some of the libraries might not be needed. While installation I should prompt users that which part they need to install.
One Solution:Logical seperation of packages may be one solution. Like packing libraries in separate packages, and required packages can be installed.
But If it has been made selective installation, then it would be more easier. I have no idea whether NuGet have such an option. Any help would be appreciated.
NuGet has support for framework versions and platforms using conventions, you can read up on them in the docs. You can group them by target framework version or by target framework profile.
If you want to selectively install libraries, you are saying you want to selectively install dependencies: you should split them up in separate NuGet packages and declare your dependencies. These dependencies also can be grouped.
If your condition cannot be defined using framework version or profile, you should come up with your own entry-level NuGet packages and bring down the proper dependency chain (or use PowerShell hooks for this).
