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 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 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.
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'm trying to get nuget package restore working in a solution that is looking for packages in the regular, public nuget feed and in a local feed located on a shared network drive.
What I've tried so far is enabling nuget package restore on the solution, then editing the Nuget.targets and changing the PackageSources variable, but that doesn't seem to work. Is this possible?
My Nuget.targets file looks like this for the package sources section:
<ItemGroup Condition=" '$(PackageSources)' == '' ">
<!-- Package sources used to restore packages. By default, registered sources under %APPDATA%\NuGet\NuGet.Config will be used -->
<!-- The official NuGet package source (https://nuget.org/api/v2/) will be excluded if package sources are specified and it does not appear in the list -->
<PackageSource Include="https://nuget.org/api/v2/" />
<PackageSource Include="\\mynetworkshare\Development\NugetPackages" />
</ItemGroup>
The error I get on build is "Unable to find version '1.0.0' of package 'MyCustomPackage'. I have verified that the nupkg exists at \\mynetworkshare\Development\NugetPackages\MyCustomPackage.1.0.0.nupkg.
The fix for me was bhuvak's answer plus I had to rename some packages.
I had been creating symbols packages (named similar to MyCustomPackage.1.0.0.symbols.nupkg) and using those from my local package feed folder. However, package restore doesn't seem to pick those up. I had to rename them, removing the .symbols portion of the file name.
After I did that, package restore works great.
Updating the sources in NuGet.targets should work.
Make sure you have added both official NuGet source and local feed explicitly in the targets file.
What error are you noticing ?
We had a similar issue to #evan. We're using the CreateNewNuGetPackageFromProjectAfterEachBuild package to create our NuGet packages on a TFS 2013 build server. We have a local, share based package source and copy the nupkg files from the build output to this share. We found that builds that reference these packages fail because NuGet package restore fails to find the packages in the local source.
Running NuGet from the command line on the build server we get strange behaviour:
nuget.exe list <search-term-for-our-packages> -allversions
always succeeds and lists each version of our packages. However, when we go to a failed build's \src folder and run
nuget.exe restore .\oursolution.sln
we always get:
Unable to find version '1.0.6.341' of package 'our.package.name'.
I tried all sorts of things to resolve this, playing with nuget.config and swapping between versions of nuget.exe but the fix was simply to do with the naming of our nupkg files. By default CreateNewNuGetPackageFromProjectAfterEachBuild names the nupkg that it generates as the package Id plus the build configuration and target. E.g.
our.package.name.1.0.6.341.Release.AnyCPU.nupkg
With this file in our package source nuget list works but nuget restore fails. When I rename the package to
our.package.name.1.0.6.341.nupkg
then nuget list and nuget restore work as expected.
Our fix is simply to modify the config file of CreateNewNuGetPackageFromProjectAfterEachBuild to prevent it including the build configuration and target. But why does nuget restore depend on the package file name whereas nuget list doesn't?
Let's say I have a project with this structure:
MyLibrary\
MyLibrary.sln
MyLibrary.Core\
MyLibrary.Core.csproj
MyLibrary.Extensions\
MyLibrary.Extensions.csproj
MyLibrary.Tests\
MyLibrary.Tests.csproj
I want to create a single NuGet package which packages MyLibrary.Core.dll and MyLibrary.Extensions.dll. I can't seem to figure out how to get NuGet to do this. I've tried building a spec file manually and I've tried building one using "nuget spec MyLibrary.Core.csproj". I've tried adding all of the DLLs to a lib/ folder which I understand to be the convention-based mechanism for adding DLLs to the package. In every case I can get the MyLibary.Core.dll to get into the package but the MyLibrary.Extensions.dll does not end up packaged along with it.
TLDR: What is the best practice for creating a NuGet package with multiple projects / assemblies? Is there a tutorial out there that focuses on this? The tutorials I've found all focus on simple single-project demos.
You'll run NuGet on a single project (or nuspec file), but it supports pointers to other projects via the file element. This element uses the names of your project's References, so you avoid having to a) find the location of other project files, and b) copy files to a particular place as a post-build step.
Supposing you have a nuspec file for MyLibrary.Core.csproj, and it references MyLibrary.Extensions and MyLibrary.Tests such that they end up in the bin directory after a build:
<package xmlns="http://schemas.microsoft.com/packaging/2010/07/nuspec.xsd">
<metadata>
...
</metadata>
<files>
<file src="bin\Release\MyLibrary.Extensions.dll" target="lib\net40" />
<file src="bin\Release\MyLibrary.Tests.dll" target="lib\net40" />
</files>
</package>
With this setup, all of your references should end up in the appropriate place in the NuGet package. You still have the hard-coded 'Release' in there, but I'd wager most probably don't distribute NuGet packages of their debug builds anyway.
Did you generate a blank nuspec file with:
nuget spec
If you use that file and then put your dlls in a folder under it named lib, it will package them up.
I had a little trouble with trying to generate a nuspec file from a project or dll. Also, if you manually reference any files in the nuspec file, the conventions are not used. This is probably the problem with nuspecs generated from dlls or projects.
Also, if you are trying to run this from a build script that executes in a different folder, you can tell nuget the location of your .\lib folder via the -BasePath command line:
build\nuget.exe pack nuget\Company.Project.nuspec -BasePath nuget\
Have you tried NuGet Package Explorer? Might be the easiest way:
http://nuget.codeplex.com/releases/view/59864
It seems your problem is the same as this question: Why doesn't nuget include the referenced project when packing?. If so, you can use the -includereferencedprojects option (See http://docs.nuget.org/docs/reference/command-line-reference#Pack_Command).
I recently published a solution for this...
My solution enables automatic creation of NuGet packages when you build the solution where each package can contain multiple assemblies, references to both external NuGets and NuGets created during the same build and even include the source code for debugging.
In your case, all you will need to do is add a new class library project to your solution, reference the projects you want to package, then add a post build event.
You can find an article with a walk-through guide here
and the source code here.
i have some tutorial how i did it with windows and visual studio:
create local folder and call it packages like: c:/packages//lib - important to create another folder in folder call it lib and past there dll.
open nuget package explorer - https://npe.codeplex.com/downloads/get/clickOnce/NuGetPackageExplorer.application
the ui very intuitive just add dll and export it to /lib (for tutorial https://blog.zwezdin.com/2014/building-nuget-packages-with-gui-tool/ it in russian but see on pictures the flow it's about 3 clicks)
it will create nuspec file
open GIT BASH - https://git-for-windows.github.io/ and navigate to: cd c: => cd packages (the path of )
*maybe on windows you will need provide developer options for windows's linux stuff (https://www.howtogeek.com/249966/how-to-install-and-use-the-linux-bash-shell-on-windows-10/)
in GIT BASH enter command: nuget add -source [options]
where: : the full name of nuspec (include .nuspec)
and: the path of folder lib in folder (c:/packages//lib)
after the action ended successfully
in GIT BASH enter another command:
nuget pack .nuspec
not in this folder you have .nupkg file.

I had the same problem and I decided to create Nuget which will allow to create other nugets from chosen project.
Package is deployed on the Nuget.org site. After referencing it in the project You need to add nuspeck file to the projects which should generate the projects.
Project with the required nuspeck file
Last thing which should be done by you is invoke command Create-Nuspec in Package Manager. Than the powershell module will take all libraries which are result of the build it will add also the required dependencies and create the nuget in the output directory.
Description about this package is placed here.
I had an issue when adding extra dlls references to a Nuget packages, and testing the package on a sample project, the extra dlls was not being added apparently, no matter the way that I create the Nuget Package.
Then I released that when you uninstall and install again a local Nuget Package with the same version number the changes no take effect, the extra dlls are not added.
So each time you uninstall the package, close visual studio and clear the Nuget Cache,
How to clear NuGet package cache using command line?
Then open again Visual Studio and reinstall the local package to make the change takes effect.
Or make the package version to increase each time to be for Visual Studio to recognize your changes.
For example:
Package-1.0.0
Package-1.0.1
Package-1.0.2
.....
To create a Nuget package from a sample project there are some ways, for example:
Right click to your Visual Studio project and choose the "Pack" option
Then install the nuget package explorer:
https://www.microsoft.com/es-ec/p/nuget-package-explorer/9wzdncrdmdm3?activetab=pivot:overviewtab
And add manually your extra references (dlls files) to your specific targets.
Create a nuget package using a .nuspec file how specified in the documentation:
https://learn.microsoft.com/en-us/nuget/guides/create-packages-for-xamarin
<files>
<file src="Plugin.LoggingLibrary\bin\Release\Plugin.LoggingLibrary.dll" target="lib\netstandard1.4\Plugin.LoggingLibrary.dll" />
<file src="Plugin.LoggingLibrary\bin\Release\Plugin.LoggingLibrary.xml" target="lib\netstandard1.4\Plugin.LoggingLibrary.xml" />
<file src="Plugin.LoggingLibrary.iOS\bin\Release\iOsDependence.dll" target="lib\Xamarin.iOS10\iOsDependence.dll" />
<file src="Plugin.LoggingLibrary.Android\bin\Release\AndroidDependence.dll" target="lib\MonoAndroid10\AndroidDependence.dll" />
</files>
In your files part add your .dll files.
And dont forget, each time you uninstall and install again the nuget package from your local source.
Or you increase the version of the package each time:
Or close Visual Studio, clean the nuget cache and Rebuild your project.
In order to take effect the changes.
