Open a windows phone 7 application In Emulator using Command Line - windows-phone-7

Question

Is there a way to open a Windows Phone 7 Application in emulator using command line?
I know that there already exists a question related to this here, but I want a simple way to start a wp7 application (having the xap file) from command line without modify the code of the application.
I know that this is possible for XNA applications (info here) but I do not know if this is possible for apps made under Silverlight framework?!
Later edit - problem RESOLVED
Looking deeply, the Justin blog seemed to be very ok for this problem I've had.
Anyway I had to make some small changes:
changed the line:
Platform WP7SDK = dsmgrObj.GetPlatforms().Single(p => p.Name == "New Windows Mobile 7 SDK");
into line:
Platform WP7SDK = dsmgrObj.GetPlatforms().Single(p => p.Name == "Windows Phone 7");
I used a foreach for retrieving the platform names:
// iterate over all platforms and write their names
foreach (Platform p in dsmgrObj.GetPlatforms().ToList<Platform>())
{
Console.WriteLine("Platform: " + p.Name);
}
and the line:
WP7Device = WP7SDK.GetDevices().Single(d => d.Name == "Windows Phone 7 Emulator");
into line:
WP7Device = WP7SDK.GetDevices().Single(d => d.Name == "Windows Phone Emulator");
Used again a foreach :
// iterate over all devces and write their names
foreach (Device d in WP7SDK.GetDevices().ToList<Device>())
{
Console.WriteLine("Device: " + d.Name);
}

As mentioned you should follow Justin Angel's blog post. The end result is a very simple command line application which you run to, amongst other things, install your XAP file to the emulator/phone and start this application.
There is one thing I would modify though. Justin's app uninstalls the previous version of your application before installing the new one. This removes all files in isolated storage, including the IsolatedStorageSettings resource. I made the following changes to update the the phone application if it already exists.
// ... code to get command line parameters, device instance etc ...
if (WP7Device.IsApplicationInstalled(appID)) {
Console.WriteLine("Found {0} XAP on Windows Phone 7 Emulator/Device...", appName);
app = WP7Device.GetApplication(appID);
app.TerminateRunningInstances();
app.UpdateApplication("NormalApp",
appLocation + #"\ApplicationIcon.png",
appLocation + #"\Bin\" + configuration + #"\" + appName + #".xap");
Console.WriteLine("{0} XAP Updated from Windows Phone 7 Emulator/Device...", appName);
} else {
// Install XAP
Console.WriteLine("Installing {0} XAP to Windows Phone 7 Emulator/Device...", appName);
app = WP7Device.InstallApplication(appID,
appID,
"NormalApp",
appLocation + #"\ApplicationIcon.png",
appLocation + #"\Bin\" + configuration + #"\" + appName + #".xap");
Console.WriteLine("{0} XAP installed to Windows Phone 7 Emulator...", appName);
}
// Launch Application
Console.WriteLine("Launching {0} on Windows Phone 7 Emulator...", appName);
app.Launch();
Console.WriteLine("Launched {0} on Windows Phone 7 Emulator...", appName);
