I have been following the instructions in the developer guide for the deployment of Windows UWP app. I have deployed my app on both a Windows 10 Phone and Desktop with the appropriate builds.
You don't mention anything about installing a new build.
I am finding that I cannot install a new build over an existing app. i have to delete the existing app first and then install my new build. This means that I lose my data and it makes testing very time consuming.
This happens with both the phone and desktop builds.
When installing a new build on a Windows 10 phone I get:
Failure
reason: Failed to start deployment. Failure text: The provided package
is already installed, and reinstallation of the package was blocked.
Check the AppXDeployment-Server event log for details.

When installing a new build on the desktop I get:
At C:\Temp\fbe17252-ad37-4e0b-bdfa-233debc9e17e-1479417903578-UWPApp_3.53.1.0_Test\Add-AppDevPackage.ps1:392 char:13

How can I install a new build without uninstalling the app first?
Thanks
