So I have setup my Xbox One as a dev device and actually was able to run my app on my Xbox, but in order to use some new APIs to turn off scaling and what not I had to change my app target version to Build 14332. Unfortunately, after doing this, I am now not able to publish or debug my app to my Xbox and I am not getting very helpful clues as to why not.
I even reverted the target version back to Build 10240 but I am still getting this error:
Severity Code Description Project File Line Suppression State Error DEP0700 : Registration of the app failed. Deployment Register operation with target volume C: on Package MyCompany.MyApp_1.1.19.0_x64__5wbv4ypmprn7c from: (AppxManifest.xml) failed with error 0x80070002. See http://go.microsoft.com/fwlink/?LinkId=235160 for help diagnosing app deployment issues. (0x80073cf9) MyCompany.MyApp
EDIT: I found a work around. Restart my Xbox One. Literally, every time I run my app, I have to restart my Xbox One! :(
