Operation could destabilize the runtime Enterprise Library 6

Operation could destabilize the runtime Enterprise Library 6

I created a .NET 4.5 Console app to try out the Semantic Logging bits in
the new Ent Lib v6. Using the sample code from the PDF:
var listener2 = new ObservableEventListener();
listener2.EnableEvents( EventSourceCore.Log , EventLevel.LogAlways ,
Keywords.All );
SinkSubscription<SqlDatabaseSink> subscription =
listener2.LogToSqlDatabase( "Demo Semantic Logging Instance" ,
ConfigurationManager.AppSettings["mdbconn"] );
Running the code immediately gives the error "Operation could destabilize
the runtime". Looking at the stack trace within the Exception helper from
VS2012, I see

Looking at the Entlib source code, line 32 in SqlDatabaseSink.cs shows
private readonly RetryPolicy retryPolicy = new
RetryPolicy<SqlDatabaseTransientErrorDetectionStrategy>(5,
TimeSpan.FromSeconds(1), TimeSpan.FromMinutes(1),
TimeSpan.FromSeconds(5));
Going to line 59 in RetryPolicyGeneric.cs that shows
public RetryPolicy(int retryCount, TimeSpan minBackoff, TimeSpan
maxBackoff, TimeSpan deltaBackoff)
: base(new T(), retryCount, minBackoff, maxBackoff, deltaBackoff)
But I don't see anything like an implicit cast that could be causing the
problem, that was found in other SO posts.
What did I miss? Has anyone actually seen the logging block work "out of
the box"?
Thanks,
