    Question How to install/update app programmatically?

    How can I let my app update itself programmatically?

    I want to update the app resources and binaries from inside the app itself.

    You can't change the binaries or built-in resources from inside the App. All those changes have to go through a store update. You can only write to the IsolatedStorage of your App.

    Probably mobi1 is referring to what some games does that is to have a base install and then when you launch it, more stuff is downloaded?

    If that the case then you need to code your app in a way that the resources that you need to download need to be loaded in runtime from the isolated storage. Depending on what the of resources we are talking about its possible but we need to know more details on whats the intended purpose.

    If you really meant upgrading the app itself: you can implement a webservice that the app can query for the newest version number. Then you can link into the store if the current app version is less than the newest version by calling the MarketplaceDetailTask.

    Thanks for your responses.

    Actually, I need the app to update itself without using the Marketplace.

    What's your use case?

    As others have mentioned, if the app is downloaded from the store, it has to be updated from the store - there are no other options in that case.
