I have a Visual Studio solution with multiple projects. There is one single csproj for every version of .NET Framework (+ .NET Core) I want to support, and I want to keep it that way. They all generate one DLL each. All DLLs are named the same but are slightly different.
I've recently started generating NuGet packages out of these DLLs using a nuspec file and the command nuget pack. So far, I've generated one NuGet package for each DLL.
Would it be possible to generate one single NuGet package, that contains all the DLLs, and when a user installs the package, installs the right DLL?
I tried the following in my nuspec file:
<?xml version="1.0" encoding="utf-8"?>
<package >
<metadata>
...
<dependencies>
<group targetFramework=".NETCoreApp3.1" />
<group targetFramework=".NETFramework4.0" />
</dependencies>
</metadata>
<files>
<file src="bin\Company.Product.dll" target="lib\net40" />
<file src="..\CompanyProductCore\bin\Company.Product.dll" target="lib\netcoreapp3.1" />
</files>
</package>
When I look in the generated NuGet package, there are the two expected subfolders in the lib folder, and they each contain a DLL which looks right.
However, when I test the package and try to install it in another Visual Studio solution on a .NET Core App project, I get the warning:
Package X was restored using '.NETFramework,Version=v4.6.1...4.6.2...4.7...4.7.1...4.7.2...4.8 instead of the project target framework '.NetCoreApp,Version=3.1'. This package may not be fully compatible with your project.
which is something that did not appear when I packed it separately. So it would seem that it didn't detect that there was a .NET Core-specific DLL given.
Is what I want to do possible, and if so, how?
Your target frameworks should be net40 and netcoreapp3.1.
<dependencies>
<group targetFramework="netcoreapp3.1" />
<group targetFramework="net40" />
</dependencies>

I have a few projects, which could be a console application, Web Application, WebAPI, MVC etc) and a normal Class Library (not Core/.Net 6) which contains Newtonsoft.Json dll (latest version).
Each of the applications have their own version of Newtonsoft.Json dll that has been added manually for that project. In doing this it means an older app could have used version 1.0 the next application could have used v 2.0 and later apps could have used a much later version etc
I would like to share this class library through a Nuget package but i have added the latest version of Newtonsoft.Json dll into my own class library.
When i create a .nuspec file i would like to exclude this file but using this code
<files>
<file src="bin\Release\Newtonsoft.dll" target="\" />
</files>
within the .nuspec file doesnt seem to work, reading https://learn.microsoft.com/en-us/nuget/reference/nuspec suggests to use the exclude but i cant get the syntax right.
What am i missing here?
In your nuspec include this:
<dependencies>
<dependency id="Newtonsoft.Json" version="[3.5,14)" />
</dependencies>
Where 3.5 is the oldest version you support and 14 is the newest you do not support.
Then you can leave out newtonsoft.dll from you own package and the project you install the nuget into will be able to determine which newtonsoft to use.
I want to create a NuGet package from a class library targeting .Net Framework 4.5 (not 4.5.1, or 4.5.2) which contains source code files, and I have trouble finding how.
The reason being that I would like to be able to debug it. I already created the symbols package, and it seems to works, provided I open the *.cs file I want to debug when VS2022 asks me for it.
To pack, I use a standard nuspec file, to which I specified the files I want to add taking inspiration from here
<contentFiles>
<files include="**\*.cs" buildAction="content" flatten="true" copyToOutput="true"/>
</contentFiles>
</metadata>
<files>
<file src="**\*.cs" target="src" />
</files>
All the files are sent to the .nupkg in a src folder, as expected.
The command I use to pack is
nuget pack *.csproj -Symbols -SymbolPackageFormat snupkg
I spent all day trying to figure out how to include source so that VS can find the source files after I install the package, to no avail. Any feedback would be appreciated.
Is there a way for this to be streamlined, or is uploading the file you want to debug the only option for 4.5?
Thanks!
As we can see that contentFiles is used for PackageReference form this link.
And .NET Framework projects support PackageReference, but currently default to packages.config.
I'm not sure which format your project is using. If you are using package.config you can try to Migrate from packages.config to PackageReference and try again.
I created a .NET framework class library targeting 4.6.1 .NET Framework. The project contains one .cs class and no external references to any libraries, DLLs, or NuGet packages. Here is the nuspec:
<?xml version="1.0" encoding="utf-8"?>
<package xmlns="http://schemas.microsoft.com/packaging/2010/07/nuspec.xsd">
<metadata>
<!-- Required elements-->
<id>MyEventLogger.Core</id>
<version>1.0.0</version>
<description>Logs event log</description>
<authors>Me</authors>
</metadata>
<files>
<file src="MyEventLogger.Core\**\bin\Debug\*.dll" target="lib\net" />
<file src="MyEventLogger.Core\**\bin\Debug\*.dll" target="lib\netstandard" />
</files>
</package>
I am having trouble importing this from an ASP.NET Core application running .NET Framework 4.7.1.
The error I get is that the package does not support any frameworks:
I am using Azure Devops Build pipeline to initiate the pack and push to a local feed. How should I reference this correctly so that an application on a newer version of .NET Framework can still use this library that is on an older version?
Thank you for any help! I can't find how to fix this error anywhere or good examples of targeting multiple .NET Frameworks.
I got it working when I was able to use the following file nodes:
<files>
<file src="**\MyEventLogger.Core.dll" target="lib\net461\MyEventLogger.Core.dll" />
</files>
What helped me figure this out was to install NuGet onto my machine as well as installing the NuGetPackageExplorer. You can create a package using the NuGetPackageExplorer and then exporting the .nuspec file. I copied that .nuspec file into my repository and then pointed my Azure DevOps build pipeline to the .nuspec file. This error disappears when I import the package into another project.
For you to be able to use code across .net framework and .net core, you need to write your code in a library written in .net standard. You may find a similar solution here
Thank you
I'm trying to figure out how to migrate a project from PCL to .netstandard 1.2.
I have a solution where I have a PCL project (portable45-net45+win8+wpa81) and a .Net Standard (netstandard1.2) project which has all it files linked into the PCL project.
Currently we create a nuget package from the PCL project using a nuspec file.
Now what would be the best approach to have both available in 1 nuget package?
I find the use of nuget pack vs dotnet pack and mixing multiple frameworks and project types (csproj) very confusing.
Also appearantly there is a new csproj format for VS2017+ projects, should I convert the PCL project?
Eventually the nuget should only contain the .netstandard1.2 project but we want to take both up the dependency tree during migration.
what would be the best approach to have both available in 1 nuget package?
You can still use .nuspec file to accomplish this, just need include the dll files from PCL project and .Net Standard project into different frameworks.
Following is my test .nuspec file, you can check it for details:
<?xml version="1.0"?>
<package >
<metadata>
<id>My.Package</id>
<version>1.0.0</version>
<authors>Tester</authors>
<owners>Tester</owners>
<requireLicenseAcceptance>false</requireLicenseAcceptance>
<description>Package description</description>
<releaseNotes>Summary of changes made in this release of the package.</releaseNotes>
<copyright>Copyright 2018</copyright>
<tags>Tag1 Tag2</tags>
</metadata>
<files>
<file src="TestPCL\bin\Debug\TestPCL.dll" target="lib\portable-net45+wp8\" />
<file src="TestStandard\bin\Debug\netstandard1.2\TestStandard.dll" target="lib\netstandard1.2\" />
</files>
</package>
When you install this package to the PCL project and .Net Standard project, nuget will select the DLL file under the corresponding framework to your project.
I'm stumped. I've followed the directions to set up a local NuGet Package Source as closely as I could, but my package refuses to show up in the NuGet Package manager. The screenshot below shows:
I've created the NuGet package
I put the package in C:\Packages
I created a package source Local that points to C:\Packages
In the Package Manager, I've selected Local as the package source
But it cannot find the package. What am I missing?
Here's my .nuspec for reference, with the assembly name removed.
<?xml version="1.0"?>
<package >
<metadata>
<id>$AssemblyName%$</id>
<version>1.2.0-beta2</version>
<title>$AssemblyName$</title>
<description>Orders Messages</description>
<language>en-US</language>
</metadata>
<files>
<file src="bin\Debug\$AssemblyName$.dll" target="lib\net40" />
</files>
</package>
Your NuGet package is a pre-release based on the version since the version in your .nuspec is:
1.2.0-beta2
So you need to check the Include prerelease check box before your NuGet package will appear in the NuGet Package Manager. Without this checked only stable versions will be displayed.
