Fixing "The remote server returned an error: (417) Expectation Failed" error while getting lic file

I got the "Send to WP7 has stopped working" message when running the just installed application (no lic file in the app directory) on my work machine (behind a proxy). The log file in the app directory had the following exception "The remote server returned an error: (417) Expectation Failed."
Creating a SendToWP7Desktop.exe.config file with the following content has fixed the problem
```<?xml version="1.0"?>
<configuration>
<system.net>
    <settings>
        <servicePointManager expect100Continue="false" />
    </settings>
</system.net>
</configuration>```

NOTE: I have not managed to build the solution on my Windows 7 x64 machine (missing Microsoft.Windows.Common-Controls assembly), so I have not got a chance to assure the fix actually works.
