App storage if submitting another xap

Question

Hi everybody,

I was wondering one thing : I have an application which stores some files in the IsolatedStorage.

I know that if I update my app with another version of the original xap, the IsolatedStorage is not deleted.

But what if I create a new projet in Visual Studio, create a new xap from this project and submit it as an update of my previous app ? Will the IsolatedStorage be deleted ?

Actually I want to update one of my app but I prefer to create it from the begining.

Thanks in advance, Rafi.

Hi,

The Marketplace ingestion process recognizes the application ID to identify the app uniqueness. When you publish an update and specify the same app id, but with a new version, then the app will use the same isolated storage.

Thanks Mark,

So what I'm going to do is to create a new WP project and put the first application's id into the new one.

I believe you will need to make sure the ID is the correct one using the Marketplace publishing web site. Marketplace overwrites any ID (the productID) that is in the wmappmanifest file.
