Azure DevOps Client Library doesn't work

I am trying to use [AzureDevOps Client NET Libraries](https://docs.microsoft.com/en-us/azure/devops/integrate/concepts/dotnet-client-libraries?view=azure-devops) to get a release, but it doesn't look like it will work with azure functions:

```
public override void Configure(IFunctionsHostBuilder builder)
{
builder.Services.AddTransient(x =>
{
var url = "";
var pat = "";
var credentials = new VssBasicCredential(string.Empty, pat);
return new VssConnection(new Uri(url), credentials); <-- Method Not Found...
});
}
```

Results in:

> Microsoft.VisualStudio.Services.WebApi: Method not found: 'Newtonsoft.Json.JsonSerializerSettings System.Net.Http.Formatting.BaseJsonMediaTypeFormatter.get_SerializerSettings()'.

I am using dotnet core 3.1. I have also tried without using DI and I get the same result. The closest thread I could find was this but the [fix doesn't work](https://developercommunity.visualstudio.com/content/problem/878381/problem-with-microsoftvisualstudioservicesclient-n.html)

I also skimmed through [this article](https://mitchdenny.com/vsts-libraries-from-dotnet-core/), but the solution is geared towards windows. I'm on a mac

It suggests:
```

portable-net451+win8

```

Here is my full csproj file:

```

Here is a repo the reproduces the issue

I also realize that this may not be the correct place for this issue, but it was the only thing I can find. The NuGet page does not provided a GitHub Repo where this is maintained.
