How to override nuget dependencies id in nuspec file - nuget

I have projectA and projectB in the same solution.
projectA creates its own package, but I override the package id by using a prefix:
<PackageIdPrefix></PackageIdPrefix>
<PackageId>$(PackageIdPrefix)$(MSBuildProjectName)</PackageId>
The command to generate the package is :
dotnet pack .\$(ProjectName).csproj --include-symbols --no-build -o C:\dev\UPP\Packages -p:PackageIdPrefix=MyPrefix."
Therefore the generated package name is MyPrefix.ProjectA.nupkg
projectB references projectA as a project reference since they belong to the same solution.
projectB creates its own package, in the same way:
<PackageIdPrefix></PackageIdPrefix>
<PackageId>$(PackageIdPrefix)$(MSBuildProjectName)</PackageId>
However in the nuspec of the generated MyPrefix.ProjectB.nupkg I end with :
<dependency id="ProjectA" version="1.0.0" exclude="Build,Analyzers" />
So the prefix was not used to create the dependency in the nuspec. Obviously this leads to an error when I try to install this package since the dependency ProjectA does not exist...
How can I prefix the dependency ?

Pack the whole solution into a single nupkg?

I have a number of helper libraries that I would like to turn into a single NuGet package:
ProjectA
ProjectB (references ProjectA)
ProjectC
I can make individual packages of these:
nuget pack ProjectA.nuspec
nuget pack ProjectB.nuspec
nuget pack ProjectC.nuspec
Or I can "bundles" of referencing projects:
nuget pack ProjectB.nuspec -IncludeReferencedProjects
nuget pack ProjectC.nuspec
But I'd very much like a single .nupkg file containing all the projects.
Is this possiblie to achieve?
-S
I ended up creating a "bundling project" that only references the other projects:
ProjectA
ProjectB (references ProjectA)
ProjectC
ProjectD (references ProjectA, ProjectB and ProjectC)
With this in place, I can pack everything into a single NuGet package.
nuget pack ProjectD.nuspec -IncludeReferencedProjects
Not super elegant to achieve, but it kind of makes sense to have a neutral project without its own functionality to bundle up the other diverse projects.

NuGet: Two packages with targets files lead to incorrectly copied DLLs

I have created two NuGet packages that contain Native Libraries. The first one has two subfolders (amd64 and x86) the second one includes the DLL flat under the build directory. The NativeLibraries of the the first package are supposed to be copied into subfolders of the OutputPath. The only DLL in the second package should be copied flat under the OutputPath. I used the following stackoverflow entry as a guide for creating the package: https://stackoverflow.com/a/30316946/4496150
The first NuGet package folder structure looks like this (amd64 and x86 subfolder under build):
build
amd64
DLL1.dll
DLL2.dll
x86
DLL1.dll
DLL2.dll
packagename.targets
First targets file:
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<ItemGroup>
<NativeLibs Include="$(MSBuildThisFileDirectory)**\*.dll" />
<None Include="#(NativeLibs)">
<Link>%(RecursiveDir)%(FileName)%(Extension)</Link>
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</None>
</ItemGroup>
</Project>
Please notice $(MSBuildThisFileDirectory)** as NativeLibs Include and %(RecursiveDir) as part of Link attribute.
The second NuGet package structure looks like this (no subfolders under build):
build
DLL1.dll
packagename.targets
Second targets file:
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<ItemGroup>
<NativeLibs Include="$(MSBuildThisFileDirectory)\*.dll" />
<None Include="#(NativeLibs)">
<Link>%(FileName)%(Extension)</Link>
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</None>
</ItemGroup>
</Project>
Please notice $(MSBuildThisFileDirectory) (without **) as NativeLibs Include and missing %(RecursiveDir) in Link attribute.
If you reference both packages, the DLLs from the first package are additionally copied flat into the output folder, which is not desired. I suspect this is because the second include step also reads the DLLs from the first package, but then does not use %(RecursiveDir).
A workaround is to also include in the second package both.
and NativeLibs Include="$(MSBuildThisFileDirectory)***.dll" /> exactly as in the first package.
However, I would prefer to understand why the second package ensures that the DLLs from the first are copied flat.
If I read https://learn.microsoft.com/de-de/visualstudio/msbuild/msbuild-reserved-and-well-known-properties?view=vs-2019 correctly, $(MSBuildThisFileDirectory) points to the folder in my NuGet cache where the targets file of the NuGet package is located. So actually everything would be correct. But still (probably) wrong DLLs are copied.
Edit
I added the following snippet in both targets files to get some output:
<Target Name="OutputPackage1NativeLibs" BeforeTargets="Build">
<Message Text="Package1 %(NativeLibs.Identity)" Importance="high"/>
</Target>
For the seconds targets file I changed the target name to OutputPackage2NativeLibs and started the text Output with Packag2.
When I clean my NuGet Package Cache and rebuild the solution everything is fine. But after the third or forth rebuild operation the DLLs of the first package are copied flat under the Output path and I get the following output:
Package1 C:\Users\USERNAME\.nuget\packages\PACKAGENAME1\1.2.3.4\build\amd64\DLL1.dll
Package1 C:\Users\USERNAME\.nuget\packages\PACKAGENAME1\1.2.3.4\build\amd64\DLL2.dll
Package1 C:\Users\USERNAME\.nuget\packages\PACKAGENAME1\1.2.3.4\build\x86\DLL1.dll
Package1 C:\Users\USERNAME\.nuget\packages\PACKAGENAME1\1.2.3.4\build\x86\DLL2.dll
Package1 C:\Users\USERNAME\.nuget\packages\PACKAGENAME2\1.0.0.0\build\DLL1.dll
Package2 C:\Users\USERNAME\.nuget\packages\PACKAGENAME1\1.2.3.4\build\amd64\DLL1.dll
Package2 C:\Users\USERNAME\.nuget\packages\PACKAGENAME1\1.2.3.4\build\amd64\DLL2.dll
Package2 C:\Users\USERNAME\.nuget\packages\PACKAGENAME1\1.2.3.4\build\x86\DLL1.dll
Package2 C:\Users\USERNAME\.nuget\packages\PACKAGENAME1\1.2.3.4\build\x86\DLL2.dll
Package2 C:\Users\USERNAME\.nuget\packages\PACKAGENAME2\1.0.0.0\build\DLL1.dll
So NativeLibs are added from the other NuGet package apparently after the third or fourth rebuild.
I think you are using Packages.config nuget package format with non-sdk net framework projects. If so, that could be explained.
For packages.config nuget management format, it imports the target files directly under csproj file. In my side, I created two nuget packages called flat 1.0.0 and faltt 1.0.0 nuget packages.
You can check my csproj file:
If so, the first import targets file flat.targets file is the same as your first nuget package's targets file:
It includes the x86 and amd64 folder files into output folder\x86 and output folder\amd64 folder, that is right as we excepted.
However, under pakckages.config, since the two targets file are in the same csproj file, they can access each other(they have the same life cycle in the same CSProj), when msbuild reads faltt.targets file after flat.targets file, also you did not change NativeLibs item for the second targets file, itself has the file:
C:\Users\xxx\source\repos\flat\packages\flat.1.0.0\build\amd64\Dll1.dll
C:\Users\xxx\source\repos\flat\packages\flat.1.0.0\build\amd64\Dll2.dll
C:\Users\xxx\source\repos\flat\packages\flat.1.0.0\build\x86\Dll1.dll
C:\Users\xxx\source\repos\flat\packages\flat.1.0.0\build\x86\Dll1.dll
When reads the flatt.targets file, it also includes C:\Users\xxx\source\repos\flat\packages\flatt.1.0.0\build\x86\Dll1.dll,
So it has five files under NativeLibs item.
And then it executes <Link>%(FileName)%(Extension)</Link>, the first nuget package's dlls will be executed under the second nuget packages's node, output to the output root folder.
Because of the special nature of Packages.config import targets files, they are interlaced.
You should note that
Under PackageReference nuget management format, the import targets files are stored under obj\xxx.csproj.nuget.g.targets file, like this:
<ImportGroup Condition=" '$(ExcludeRestorePackageImports)' != 'true' ">
<Import Project="$(NuGetPackageRoot)flatt\1.0.0\build\flatt.targets" Condition="Exists('$(NuGetPackageRoot)flatt\1.0.0\build\flatt.targets')" />
<Import Project="$(NuGetPackageRoot)flat\1.0.0\build\flat.targets" Condition="Exists('$(NuGetPackageRoot)flat\1.0.0\build\flat.targets')" />
</ImportGroup>
Since the content is not in csproj file and the particularity of the file xxx.csproj.nuget.g.targets, it will read the targets files in each nuget package separately. Each file is a separate life cycle, so it does not Will affect each other. This is also one of the advantages of the latest PackagesReference nuget management format.
Sorry for not telling you at the beginning that I was using packagesReference and I didn't notice packages.config.
So if you want to get the right behavior to separate them, try the two approaches:
1) do not change the two nuget packages, right-click on the packages.config file of the main project which installs the two nuget packages-->click Migrate packages.config to PackageReference option
After that, click Rebuild option to get that.
2) modify the nuget packages--> change the NativeLibs item's name to another for the second nuget package targets file:
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<ItemGroup>
<NativeLibs1 Include="$(MSBuildThisFileDirectory)*.dll" />
<None Include="#(NativeLibs1)">
<Link>%(FileName)%(Extension)</Link>
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</None>
</ItemGroup>
</Project>
When re-pack your project, uninstall them first, delete all cache files under C:\Users\xxx\.nuget\packages. And then re-install the packages again.

Paket include-referenced-projects with project references

I have a solution that looks like this:
-> Proj A
-> proj B
Proj B references Proj A
Both projects have a paket.template that looks like this:
When I paket pack, I get two nugets created, one for each project. Fantastic.
However, I now want to make ProjA.dll be bundled inside ProjB's nuget (ProjB is an .exe/tool that needs its dependencies bundled to operate).
Adding include-referenced-projects true to ProjBs paket.template has no effect, neither does any combination of paket command line --include-referenced-projects true that I've tried.
Is this supported? Is this a bug?
Either way, how can I achieve what I want, without making separate solutions to house ProjA and ProjB?
If you look at ProjB.nuspec from resulting nuget package you see nuget reference to ProjA package. So resulting ProjB package has all needed dependencies.
You can achive what you want by several ways:
Pack ProjB by command paket pack <output> --template <path to ProjB paket.tempplate> (without --include-referenced-projects flag). Pack ProjA by separate command if you need it.
Delete paket.template from ProjA, then pack ProjB with --include-referenced-projects flag. But in this case package for ProjA will not be created.
Change paket.template type for ProjB from "project" to "file" and specify all dependencies and files manually.
(HACK:)) you can rename paket.template for ProjA from paket.template to <somethingElse>.template and pack ProjB with --include-referenced-projects flag.
Paket will not find than ProjA produce nuget package and add it as binary dependency to ProjB. You still can pack ProjA with separate command paket pack --template "path to <somethingElse>.template"

Creating Multiple Nuspec files

I am currently trying to publish a load of nuget packages for all the projects in this solution. The projects are setup in a simple tree, with Myre being the base project and everything depending on it:
Myre <- Myre.Debugging <- Myre.Debugging.UI <- Myre.UI
Myre <- Myre.UI
Myre <- Myre.Entities <- Myre.Graphics
I'm trying to package up each separate project as a nuget package with the correct dependencies on the other Myre subproject packages as necessary.
My first step was to make a package for Myre (nuspec and bat file of process). This seems to work nicely, the gallery shows Myre as having a ninject (another nuget package) dependency and all is well.
The problem comes when I tried to make the next package. Myre.Debugging depends upon Myre (with a normal project reference) and nothing else. Using this nuspec with nuget pack (verbose) gives:
Attempting to build package from '(x86) Myre.Debugging.csproj'.
Packing files from 'C:\Long_Path\Myre\Myre.Debugging\bin\x86\Release'.
Add file 'C:\Long_Path\Myre\Myre.Debugging\bin\x86\Release\Myre.Debugging.dll' to package as 'lib\net40-Client\Myre.Debugging.dll'
Add file 'C:\Long_Path\Myre\Myre\bin\x86\Release\Myre.dll' to package as 'lib\net40-Client\Myre.dll'
Add file 'C:\Long_Path\Myre\Myre\bin\x86\Release\Myre.XML' to package as 'lib\net40-Client\Myre.XML'
Found packages.config. Using packages listed as dependencies
Id: Myre.Debugging
Version: 1.0.0.2
Authors: Microsoft
Description: Description
Dependencies: Ninject (= 3.0.1.10)
Added file 'lib\net40-Client\Myre.Debugging.dll'.
Added file 'lib\net40-Client\Myre.dll'.
Added file 'lib\net40-Client\Myre.XML'.
Successfully created package 'C:\Long_Path\Myre\Myre.Debugging\Myre.Debugging.1.0.0.2.nupkg'.
As you can see it picks up a packages.config file (presumably from Myre since there isn't one here) which it then determines a Ninject dependency from. If I wanted Myre.Debugging and Myre to be a single package that would be fine. However this is not what I want, I want Myre.Debugging to pick up a dependency on the Myre package.
How can I setup nuget to use Myre as a package reference and not simply to copy the Myre assemblies into the Myre.Debugging package?
Edit:: I tried not using -IncludeReferencedProjects and specifying:
<dependencies>
<dependency id="Myre" version="1.0.0.1" />
</dependencies>
But for some reason this just creates a package with no dependencies at all! Even if manually specifying dependencies like this did work, it's hardly ideal.
According to the NuGet command line reference for the Pack command, the IncludeReferencedProjects switch works as follows:
Include referenced projects either as dependencies or as part of the package. If a referenced project has a corresponding nuspec file that has the same name as the project, then that referenced project is added as a dependency. Otherwise, the referenced project is added as part of the package.
In your case, Myre.Debugging.nuspec does not match the project file names: (x86) Myre.Debugging.csproj, etc. I suspect that you'll need to match up those file names to get that command line option to work.
Alternatively, if you want to get this to work with a <dependencies> element in your nuspec file, you may be facing another variant on the name mismatch problem. Your Myre.nuspec file defines its ID as follows:
<id>$id$</id>
The NuSpec reference says that the $id$ token is replaced by "The Assembly name." If it's talking about the name of the DLL (ignoring the extension), then I think the generated IDs will be (x86) Myre, etc. You might want to try hard-coding the ID temporarily just to see if that resolves the issue.
I haven't tried making these suggested changes, and I can't guarantee they will work, but I hope this points you in the right direction. Good luck!

NuGet Assembly outside lib folder

I'm going to bang out a couple of questions here...first, with NuGet is it possible to create a package from a few DLLs? There is no visual studio project, just the command line and a couple of pre-compiled DLL files.
Second, assuming that is possible, why do I continuously get the "Assembly outside of the lib folder" warning? I've tried everything I can think of to get associated assemblies to add themselves as references inside of the NuGet package.
My file structure looks like this
Root
- File1.dll
- lib
- File2.dll
- File3.dll
When I tell NuGet to pack it using a .nuspec like this
<?xml version="1.0"?>
<package >
<metadata>
<id>File1.dll</id>
<version>1.0.0</version>
<authors>thisguy</authors>
<owners>thisguysmom</owners>
<requireLicenseAcceptance>false</requireLicenseAcceptance>
<description>This is some library</description>
<releaseNotes>Porting to NuGet</releaseNotes>
<copyright>Copyright 2012</copyright>
<references>
<reference file="File2.dll" />
<reference file="File3.dll" />
</references>
</metadata>
</package>
I receive that warning. From what I'm reading, I shouldn't even have to define the references node in any of my projects, as the lib folder items should automatically be added as references?
Does anyone out there understand this NuGet mess?
I just ran into this problem. Nuget is expecting a structure that looks like:
root
- lib
- net40
- File1.dll
- File2.dll
- File3.dll
net40 or net20 or net45 as appropriate to your .net version.
run
nuget pack yourlibrary.nuspec
to package it up.
That will pack up the dir wholesale and put it in the nupkg. The error messages will disappear at that point.
Any dll that you want referenced should be under the lib folder. The warning is because file1.dll is outside lib and will be ignored during package installation. (Other special folder are "content" and "tools")
I'd used this structure :
Root
- lib
- File1.dll
- File2.dll
- File3.dll
See : http://docs.nuget.org/docs/creating-packages/creating-and-publishing-a-package#Package_Conventions for additional details.
With the version of NuGet that is current as of this post (and I assume later versions as well), you can use the .csproj file, in tandem with the .nuspec file to create the package. What we did was make a .nuspec file (using nuget spec and then customizing it) and include it in the project.
With the customized .nuspec file, we used the command:
nuget pack sample.csproj -IncludeReferencedProjects
At that point it built the .nupkg and did not emit issues. The .nupkg file showed up in the normal output folder (in my default case, bin\debug).
You may add references to another dll by adding below inside tag in nuspec file
<package>
<metadata>
...
</metadata>
<files>
<file src="..\ReferencedFolder\*.*" target="lib\net40\" />
</files>
</package>
Alexandre is referring to the "lib" folder that gets created when you create a NuGet package. You can open the .nupkg just like you would any zip file. In there, you will see a lib\netXX folder where XX is the version of the .NET framework you're targeting. So when you're packing your NuGet file, make sure File1.dll is inside the lib folder.
I used Prof Von Lemongargle' solution, and for me was a great solution.
Important:
Include spec file (with right-click-> Include in project) in the project
Give to spec file THE SAME FILENAME of your project (myproject.csproj, myproject.nuspec)
This work perfectly in Visual Studio 2012.
They get into the "lib" folder by being included in your bin\debug or bin\release folder in .NET. So you need to get the project compile to copy local on the external DLLs so it includes them in the bin folder on compile.
If dependencies or libraries have been changed, old files affect the packaging operation.
Remove obj and bin folders from project.
Run dotnet restore
Run nuget pack yournuspecfile.nuspec -properties Configuration=Release -IncludeReferencedProjects or your command whatever.
