How does NuGet contentFiles work?

Question

I'm trying to create a nuget package with content which work with different kinds of projects.

TestSource.nuspec look like this:
<contentFiles> <files include="csanyTestSource.cs" buildAction="Compile" /> </contentFiles> </metadata> <files> <file src="TestFolderTestSource.cs" target="content/TestFolder" /> </files> (the file is available both as contentFilescsanyTestSource.cs and TestFolderTestSource.cs)

The created package works fine in a "normal" project but nothing happens in a packagereference project.

I assume I'm missing something simple

Found this out myself.

You need to add the file twice in the files section

  <contentFiles>
    <files include="csanyTestSource.cs" buildAction="Compile" />
  </contentFiles>
</metadata>
<files> 
  <file src="TestFolderTestSource.cs" target="content/TestFolder" />
  <file src="TestFolderTestSource.cs" target="contentFiles/cs/any" />
</files>

The package will then work for both normal and packagereference projects.
