Is moonlight based on the latest git master or 2-10? Isn't moonlight taking some old revision between "our verifier disabled entire WCF proxy" and "the verifier temporarily disabled the verification that blocked WCF" ?

We're currently using 651c8b350 . I thought this contained your workaround/fix for the unverifiable proxies.

Then yes it should be based on RealProxy, and I have no idea why it raises SecurityException. Is it because RealProxy is not public in moonlight?

CCing Rodrigo.

The verifier error is:

Mono: Inheritance failure for type System.ServiceModel.ClientRealProxy. Parent class System.Runtime.Remoting.Proxies.RealProxy is more restricted.

The two classes are both internal but they exist in two different assemblies, mscorlib and system.servicemodel. It looks like the verifier does not like this even though corlib has internalsVisibleTo System.ServiceModel.

This is a core-clr issue. Not sure how should we handle it.

the new code path hits a bunch of security critical code that will need to be relaxed (into SSC) then audited -> assigning to myself

With mono master (i.e. not moon current rev) I get up to:

Is that expected ?

Yes, this is an issue we currently hit and need to figure it out. If thats the only exception you're getting then the verifier issue must be resolved.

ok, back to Atsushi

There is no repro description.

Rodrigo, you wanted something specific tested (env var) before removing the
workaround ?

Atsushi, I've been using this URL (from Alan)
