title: ThreadPool Windows phone App 8.1
body: <p>I'm developing Windows phone app. I stay at Write Database concurrent. But i know can't write database concurrent. I should use ThreadPool to push some Thread into queue. And process sequence. To avoid write DB concurrent. But I can't clearly some example in MSDN. Anyone know. Now I just have 2 method Async. And inside it have instruction to write database.</p>
