To get started, you first fire up Visual Studio Express 2010 and create a project. 1. To launch Visual Studio 2010 Express, select Windows Start All Programs Microsoft Visual Studio 2010 Express Microsoft Visual Studio 2010 Express for Windows Phone. Create a new project by selecting File New Project on the Visual Studio menu, as shown in Figure 2 1.

Figure 3-5. Completed connection That s how you establish the connections between two activities. Hover over the predecessor until you see the connection points, click one, drag the mouse to the successor until you see its connection points, and let the mouse button up.

A Message object is generated by a special MessageSink (the ChannelSink) and passed through a chain of MessageSinks. When received by the Dispatcher, it will be translated into a method call on the server-side.

To turn the reported Total CPU sort cost into standard units, we divide by 5,000,000 (the 500 MHz * 10,000 microsecond sreadtim) to get Cost of join = 2,517 + 5,018,650 / 5,000,000 + 631 + 5,033,608 / 5,000,000 = 3,148 + 2 and a bit. You can see at the end of the following section that the actual cost quoted for the merge is 3,151, which compares well with the 3,150 plus a bit that I have just calculated. Since I can t guarantee the timing, or direction, of rounding used, I can t be certain whether the difference of one is due to rounding, or to a small cost that is directly attributable to the merge operation itself.
