Answer 1

Not really the answer to my question, but an alternate approach of implementing the WCF service (in .NET 4.5) that does not exhibit the same issues with Thread.CurrentPrincipal.

    public async Task Method1()
    {
        // Audit log call (uses Thread.CurrentPrincipal)

        try
        {
            return await Task.Factory.StartNew(() => this.WorkerFunction());
        }
        finally 
        {
            // Audit log result (uses Thread.CurrentPrincipal)
        }
    }

    private string WorkerFunction()
    {
        // perform work
        return string.Empty;
    }
