We are trying to use Microsoft.Azure.EventHubs.ServiceFabricProcessor, Version=0.5.2.0 in our Azure service fabric stateful service ( .NET Framework 4.7.2) and receiving the error:

Code Snippet

    internal sealed class WebHooksProcessor : StatefulService
{
    private bool _keepGoing = true;

    public WebHooksProcessor(StatefulServiceContext context)
        : base(context)
    {
    }

    protected override async Task RunAsync(CancellationToken cancellationToken)
    {
        try
        {
            EventProcessorOptions options = new EventProcessorOptions();
            options.OnShutdown = OnShutdown;
            ServiceFabricProcessor processorService = new ServiceFabricProcessor(Context.ServiceName, Context.PartitionId, StateManager, Partition,
                new HookEventsProcessor(), "Connection string", "$Default", options);

            Task processingTask = processorService.RunAsync(cancellationToken);

            while (_keepGoing)
            {
                Thread.Sleep(1000);
            }

            await processingTask;
        }
        catch (Exception ex)
        {
            ServiceEventSource.Current.Message("WebHooksProcessor.RunAsync() error: {0}", ex);
        }
    }

    private void OnShutdown(Exception e)
    {
        _keepGoing = false;
    }
}

Expected behavior
Provides events from EventHub for IEventProcessor implementation without errors

Thank you for opening this issue! We are routing it to the appropriate team for follow up.

I just confirmed that the 5.2.0 version of the library on nuget https://www.nuget.org/packages/Microsoft.Azure.EventHubs.ServiceFabricProcessor/0.5.2 is delay signed and not fully signed.

@jsquire do you know who would be the correct person to produce a new build to fix this issue?

[jsquire]

@AlexGhiondea: This should be a small change with minor version bump. Any objections to me doing this as a one-off?

@serkantkaraca: Are there any concerns around doing a release of ServiceFabricProcessor with bump to 0.5.3 just to push it through the central engineering system with a new signature?

[AlexZbn]

Hello, is there any progress?

[jsquire]

Hi @AlexZbn. Apologies for the delay; we've cut a new build and validated the signature. The package is queued to be published, so it should be available in the next couple of days. Once I've got confirmation, I'll ping this issue to let you know.

[jsquire]

@AlexZbn: The new package has been published, and can be found here: https://www.nuget.org/packages/Microsoft.Azure.EventHubs.ServiceFabricProcessor/0.5.3. Please let us know if you run into any further difficulties.

Thank you!
