Good morning,

I have a desktop application in .net framework 4.8 and now I could create manual transactions with this configuration:

```auto
Agent.Subscribe(New HttpDiagnosticsSubscriber())
Agent.Setup(New AgentComponents())

```

Package: elastic.Apm

But I would like see the sqlspans. I have review that I use sql queries inside a created transaction but not appears. I have read that I must add this line:

```auto
- Agent.Subscribe(New SqlClientDiagnosticSubscriber())

```

I have add it after the Setup but now I have an error about:

```auto
System.MethodAccessException: 'Error cuando el método 'Elastic.Apm.SqlClient.SqlClientDiagnosticSubscriber.Subscribe(Elastic.Apm.IApmAgent)' intentó obtener acceso al método 'Elastic.Apm.CompositeDisposable..ctor()'.'

```

Any help would be greatly appreciated.

Thanks!!
