Hello,

I'm currently having some issue configuration our applications with APM.  
We are running .net Framework 4.6.1 and I managed to have the transactions showing up on Kibana.  
Problem is, all transactions have one 1 span. I tried updating the System.Diagnostics.DiagnosticSource package to the latest version, but I still get the same result.

Thanks in advance for your help.

Hi @LaurentV,

what other span would you expect there? Asking because this really depends on what your application is doing. There was a very similar discussion [here](https://discuss.elastic.co/t/elastic-apm-net-agent-is-not-instrumenting-methods/228815/4) . Maybe that's worth looking at.

Hello @GregKalapos,

Thank you for your support. For example, I would expect a span to be created when we call an external API (in this case via WCF). I also tried to instrument EF but with no success so far. But I guess that is another issue.

Thanks

Hey @LaurentV

> I would expect a span to be created when we call an external API (in this case via WCF)

If you call it with the `HttpClient` class then it should show up. If you call it with some older technology or it's not HTTP binding then it's unfortunately not supported at this point.

> I also tried to instrument EF but with no success so far. But I guess that is another issue.

I'm not sure here, [here](https://www.elastic.co/guide/en/apm/agent/dotnet/current/setup.html#setup-ef6) we have info on that. Also if it's talking to SQL Server, maybe [this part](https://www.elastic.co/guide/en/apm/agent/dotnet/current/setup.html#setup-sqlclient) could also help.
