Proxy's Dispose results in Exception

A while ago I grabbed a WCF Membership example from here. Now that I've been reading some more on WCF, I stumbled upon the following article: http://msdn.microsoft.com/en-us/library/aa355056.aspx

How do you see this? Have you ever had these 'errors from IDisposable' surface in production? Did you start rewriting every client call with try-catch-finally? Personally I'm a bit appalled by the idea... Using the using statement keeps the code clean.

So I started searching for a solution. This article (WCF Gotcha #1) seems to provide a nice solution, but it's not exactly what I was hoping for.

Ideas are very welcome!
