UWP App deploy error

Question

I have two versions of one application in one project/solution with only one difference - app name. After installation one of them, the second app cant deploy:

2>Deploying to Phone Internal Storage...
2>Updating the layout...
2>Copying files: Total <1 mb to layout...
2>Checking whether required frameworks are installed...
2>Registering the application to run from layout...
2>DEP0001 : Unexpected Error: -2147009287
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
========== Deploy: 0 succeeded, 1 failed, 0 skipped ==========\

Is there any unique data in Package.appxmanifest or Package.StoreAssociation.xml which should be changed ?

Answer 1

Yes, you need to change the Package.appxmanifest for each app.

In general you need a different Package Family Name for each app you install.

When deploying to a phone things are slightly different. The phone uses an Id for each installed app. This is defined as the PhoneProductId attribute of the PhoneIdentity element in the Package. You need to edit the XML directly to change this. (Right click the file, select 'Open With...' and then select a suitable editor.)

If you're distributing through the store then the project will be associated with the store and so changing the name will not be sufficient to create a new store entry. You'll need a different store association for each entry in the store.
