Repro Steps & Context

When updating the Azure.Core package from version 1.50.0 to 1.51.1, the existing reference to the System.ValueTuple package gets removed, breaking the ability to run.

This gets removed from the .csproj file:

    <Reference Include="System.ValueTuple">
      <HintPath>..\packages\System.ValueTuple.4.5.0\lib\net47\System.ValueTuple.dll</HintPath>
      <Private>True</Private>
    </Reference>

I created a new C# project and added a package reference to Azure.Core version 1.50.0, System.ValueTuple version 4.6.1 is installed.

This is what the project looks like:

There is no reference assembly added like your XML snippet. Was the project or the packages.config edited manually? Are there precise steps we can follow to reproduce the problem and investigate further?

[ccarmannt]

Hi, @jeffkl. Thanks for the response.

My project started, as you can see in my original note, with System.ValueTuple at 4.5.0, but you started yours at 4.6.1.
Can you reproduce the issue if you start with the 4.5.0 version?

But, no, no manual editing has been done.

Okay if I only install System.ValueTuple version 4.5.0, the project looks like this:

I think what's happening is that when you update Azure.Core from version 1.50.0, NuGet is also updated System.ValueTuple to version 4.6.1 and between version 4.5.0 and 4.6.1, System.ValueTuple changed to no longer have a reference assembly?

So it would appear that NuGet Package Manager is working as designed, updating a transitive package, but that upgrade is causing build errors for you.

Azure.Core version 1.50.0 depends on System.Text.Json version 8.0.6 which depends on System.ValueTuple version 4.6.1. So I'm not sure how you ended up referencing Azure.Core 1.50.0 but System.ValueTuple 4.5.0.

So it would appear that NuGet Package Manager is working as designed, updating a transitive package, but that upgrade is causing build errors for you.

Removing references that are required for the system to function is not working. IF it was designed to destroy functional projects, that's the only way it could be "working as designed".
