**Kibana version** : 7.8.0

**Elasticsearch version** : 7.8.0

**APM Server version** : 7.8.0

**APM Agent language and version** : .NET Framework / 1.6.1

**Browser version** : Latest of Chrome

**Original install method (e.g. download page, yum, deb, from source, etc.) and version**: Docker.

**Fresh install or upgraded from other version?** Fresh

**Is there anything special in your setup?** No

**Description of the problem including expected versus actual behavior. Please include screenshots (if relevant)**:  
I've created a test project with a WCF service and I can see the ElasticAPM agent auto creates spans for WCF calls, as shown below.

But in my production project the WCF calls are not showing up. I'm using the same server and agent version. Any ideas how to troubleshoot this?

Hi @Sergio_Charpinel,

Look at the [troubleshooting section of our docs](https://www.elastic.co/guide/en/apm/agent/dotnet/current/troubleshooting.html). If you can’t figure it out, try to collect logs from the agent and paste the logs here. With that hopefully we’ll be able to help more.
