Unable to load DLL 'Microsoft.Azure.Documents.ServiceInterop.dll' using 3.0.0.10-preview

Describe the bug Running a slightly modified version of the sample application (netcoreapp3.0) using 3.0.0.10-preview. There is no exception with 3.0.0.9-preview.

var query = new CosmosSqlQueryDefinition($"select * from table s where s.{nameof(IVirtualActorDefinition.Id)} = @{nameof(IVirtualActorDefinition.Id)} ")
    .UseParameter($"@{nameof(IVirtualActorDefinition.Id)}", reference.Id);

// Use the query to get the cosmos response message and access the stream directly
var streamResultSet = _container.Items.CreateItemQueryAsStream(query, 0, partitionKey: (int)reference.ActorType, maxItemCount: 10);

var resultsFromStream = new List<IVirtualActorDefinition>();
while (streamResultSet.HasMoreResults)
{
    using var responseMessage = await streamResultSet.FetchNextSetAsync();
    // Item stream operations do not throw exceptions for better performance
    if (responseMessage.IsSuccess)
    {
        var results = FromStream<IVirtualActorDefinition[]>(responseMessage.Content);
        _logger.LogInformation($"\n1.4.1 - Item Query via stream {results.Length}");
    }
    else
    {
        _logger.LogError($"Query item from stream failed. Status code: {responseMessage.StatusCode} Message: {responseMessage.ErrorMessage}");
    }
}

the streamResultSet.FetchNextSetAsync() throws

Additional context I’m not sure why it is trying to load that dll when Microsoft.Azure.Cosmos.ServiceInterop.dll is in the bin directory

[FrankGagnon]

Here’s what’s happening. I’m pulling the Microsoft.Azure.Cosmos nuget package in Project A. The Microsoft.Azure.Cosmos.ServiceInterop.dll reference is copied to Project A’s bin. Then Project B pulls Project A’s dll. Microsoft.Azure.Cosmos.ServiceInterop.dll is NOT copied to Project B’s bin. Even though this is annoying, the easy solution it to pull directly on the Microsoft.Azure.Cosmos nuget package in Project B.

Now, Project B is a .Net 4.7.2 ASP.NET application running in IIS 10. When the application is running, IIS shadow copies the managed references from the bin folder of the application to another temporary folder on the machine. The unmanaged references like Microsoft.Azure.Cosmos.ServiceInterop.dll are NOT copied to those folders so the application fails runtime because it cannot find it.

Simillar problem discussion : https://stackoverflow.com/questions/344608/unmanaged-dlls-fail-to-load-on-asp-net-server/4598747

Do you have any suggestions as to how to make this work in IIS?

Upgrade to 3.0.0 stable release solved this problem
