Install other applications in a WP7 application Programatically

What the WP7 application needs to do?
- download some others applications and install them automatically on the device. The device will send first a request to a web server with some rules and will receive an answer containing the links to the applications that need to be downloaded and installed on the device.

As far as I read, the Marketplace is the only way to get apps on a Windows Phone 7 device, so let's suppose that the applications I want to install are already on the Marketplace and I can refer to each one by their links (according to this post).

  1. Can I download programmatically an application from the MarketPlace (having the link to it) in another application and install it on the device? I do not want to open the app link in browser because this opens the Marketplace hub and points me to the application location.

  2. Just for my curiosity: every time you want to install an application from Marketplace you need to sign in with a Windows Live ID?

Thanks & Regards, Paul

Solution
    1. You cannot dynamically download or execute code or install applications on WP7. The closest you can get is launching a MarketplaceDetailTask which directs the user to a page on the marketplace where they can choose to download the application.
    2. The user's Live ID remains signed in until they sign out from Settings so, no, they don't have to sign in more than once.
