Unable to load DLL 'Microsoft.Azure.Documents.ServiceInterop.dll' [using Microsoft.Azure.WebJobs.Extensions.CosmosDB version 3.0.0-beta7]

I am using the following packages.

<PropertyGroup>
    <TargetFramework>netstandard2.0</TargetFramework>
    <AzureFunctionsVersion>v2</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.Azure.WebJobs.Extensions.CosmosDB" Version="3.0.0-beta7" />
    <PackageReference Include="Microsoft.DotNet.Analyzers.Compatibility" Version="0.2.12-alpha" />

    <PackageReference Include="Newtonsoft.Json" Version="10.0.3" />
    <PackageReference Include="stream-net" Version="2.0.3" />
  </ItemGroup>

I am using Visual studio version 15.6.4 with Azure Functions and WebJob Tools version 15.0.4045.0. Get the following exception when I run a basic CosmosDB changefeed processing function.

Here's the code in my azure function

    [FunctionName("StreamInserter")]
    public static void Run(
        [CosmosDBTrigger("db-local", "socialData", ConnectionStringSetting="CosmosDBConnectionString", LeaseDatabaseName ="db-local", LeaseCollectionName = "leases", LeasesCollectionThroughput = 400)]
        IReadOnlyList<Document> changedFeedItems, 
        TraceWriter log,
        ExecutionContext context)
{
                    log.Info($"Received {changedFeedItems.Count} Documents from change feed processor");
}
