.NET Questions about WCF, HttpClient, Async-Await, Threads

Hi,

i am evaluating for my company a APM solution.

The followinf things did not work OOTB and some other i have questions about.

1. I do not see our outgoing WCF calls anywhere. The code is generated from WSDL and the binding is basicHttpBinding. Any ideas?
2. Not all outbound calls are catched (only the ones using the older WebRequest)
   1. HttpClient is not supported?
   2. CouchBase client needs custom config?
   3. Redis?
3. On a slow transaction the monitoring shows onlty the Thrad.Join on a started thread, missing all the actual work that is done in the thread. Is this expected?
4. Is async-await and TPL supported?
5. Do i have control over the scaling of custom Performance counter?

Thanks
