title: Does Microsoft use WCF or EF in their products?
body: <p>I'm failed to use WCF in my product as it isn't real time enough and we have to combine WCF + WCF data service which it is a bit convoluted.
  I'm wondering if MS really uses their technologies for their products. Could anyone please point out at least one microsoft product that uses any of WCF or EF related.
  it is clear to me that the technology will be soon disappear if they are not using the technology.</p>
