Packing static content in Nuget for PackageReferece projects - nuget

Question

I have a Class Library (net47) project and I'd like to pack into a nuget my dll and several files of static content (js, css, images...). I want to use this dll and the content from the consumer projects. These projects will be MVC PackageReference projects. In these projects the local static files are in the wwwroot folder.
I have tried this: NuGet ContentFiles Demystified but I get my js and css files referenced (they aren't copied to my project content).
In my nuspec I've tried with all build options: EmbeddedResource, Content, None and Compile, but these references are imported always in Compile mode. So I get a compile error when I start debugging.
I know this was possible with Package.config projects and it's very simple but all my consumer projects will be PackageReference.
This is my nuspec
<?xml version="1.0" encoding="utf-8"?>
<package xmlns="http://schemas.microsoft.com/packaging/2011/08/nuspec.xsd">
<metadata>
<id>MyProject</id>
<version>1.0.0</version>

</contentFiles>
</metadata>
<files>
<file src="contentFiles/any/any/bd.js" target="contentFiles/any/any/bd.js" />
</files>
</package>
I pack my nuget with this powershell command:
nuget pack MyProject.nuspec
Although I have also tried with the csproj:
nuget pack MyProject.csproj
And my source folder structure is this:
C:\...[projectPath]...\contentFiles\any\any\bd.js
Installation is ignoring my build action.
Why is always trying to compile my content files? Is there a better way to add static content to the consumer project?

Answer 1

Installation is ignoring my build action. Why is always trying to compile my content files? Is there a better way to add static content to the consumer project?
To answer your previous question Packing files on nuget, I have created a sample nuget package and set the build action to content for the content files, after install that nuget package, the build action would be set content:
Then I checked your .nuspec file, found it should be correct. So the issue is not related to your .nuspec file.
Besides, in the above image, you will notice that the path of the content file is nuget local cache:
C:\Users\<UserName>\.nuget\packages\
NuGet will first extract the nuget package from the local cache when install the nuget package to avoid downloading packages that are already on the computer. In other wards, although we have updated the nuget package in the local, nuget will detect the local cache first, if it found the same package in the cache, nuget will install it from cache rather than local feed.
To resolve this issue, please try to remove your nuget package in the local cache before installing the updated nuget package. Generally, when we package the same package again, wed better change the package version in the.nuspec` file so nuget local cache will not catch them.
Update for comment:
I've tried increasing the version number and deleting the nuget cache and the problem persists. My build action is always set to "C# Compiler". I just tried changing the name of the js file and the project imports the new name so I do not think it's a cache problem
After test your nuget package, I found the reason why you get that issue, we should keep the path the src and target paths are the same in the .nuspec file. Since you want set content file to the wwwroot folder, you should set the file in the wwwroot folder, then pack the .nuspec:
<contentFiles>
<files include="any/any/wwwroot/css/bd.css" buildAction="Content" copyToOutput="false" flatten="true" />
<files include="any/any/wwwroot/js/bd.js" buildAction="Content" copyToOutput="false" flatten="true" />
</contentFiles>
Following in my .nuspec scripts(Not need content node):
<?xml version="1.0" encoding="utf-8"?>
<package xmlns="http://schemas.microsoft.com/packaging/2013/05/nuspec.xsd">
<metadata>
<id>BancaDigitalViewProvider</id>

</contentFiles>

<file src="bin\debug\BancaDigitalViewProvider.dll" target="lib\net47\BancaDigitalViewProvider.dll" />
</files>
</package>
This is nuget package:

You can download it and test.
Then install it to the ASP.NET core MVC project:
Hope this helps.
