WCF concurrency, throughput and throttling

Michele Leroux Bustamante (aka "Das Blonde") wrote a great post on WCF callback scenarios:

Callback Sync Context	Callback Concurr. Mode	Service Operation	Callback Operation	Service Concurr. Mode	Resulting Behavior
True/ False	Single/ Reentrant/ Multiple	One-way/ Two-way	Two-way	Single	These are defaults. InvalidOperationException at the service. Operation would deadlock calling the client application since the callback is two-way and reentrancy isn’t possible.
True	Single/ Reentrant/ Multiple	Two-way	Two-way	Reentrant/ Multiple	Service able to call client, but client is blocked because of outgoing call.
False	Single/ Reentrant/ Multiple	Two-way	Two-way	Reentrant/ Multiple	Service able to call client, client callback object is not blocked. If client callback object tries to communicate with UI thread (i.e., setting properties of controls) it will block.
False	Single	One-way	Two-way	Reentrant/ Multiple	Service able to call client, client callback object is not blocked. Client callback object can communicate with UI thread using Invoke() from callback thread. Client can issue multiple calls to service but only one callback can be processed at a time.
False	Multiple	One-way	Two-way	Reentrant/ Multiple	Service able to call client, client callback object is not blocked. Client callback object can communicate with UI thread using Invoke() from callback thread. Client can issue multiple calls and multiple callbacks can be processed at a time.
False	Multiple	One-way	One-way	Single/ Reentrant/ Multiple	Service able to call client, client callback object is not blocked. Client callback object can communicate with UI thread using Invoke() from callback thread. Client can issue multiple calls and multiple callbacks can be processed at a time.
False	Multiple	Two-way/ Multi-threaded Client	Two-way	Reentrant/ Multiple	Service able to call client, client callback object is not blocked. Client callback object can communicate with UI thread using Invoke() from callback thread. Multiple calls from client can be processed at the service, and multiple callbacks can be processed at the client.
False	Multiple	Two-way/ Multi-threaded Client	Two-way	Reentrant/ Multiple	Service able to call client, client callback object is not blocked. Client callback can communicate with UI thread using Invoke() from callback thread. Multiple calls from client can be processed at the service, and multiple callbacks can be processed at the client.
