Yes, we will be adding DefenderUI and DefenderUI Pro to the app store, assuming that they are approved by Microsoft.
It's funny, one of the components we are adding to DefernderUI Pro is the WDAC Wizard, which is written by Microsoft in C# (our language), is open source, and includes a perfect example of what needs to be done to submit the app to the app store.
Having said that, DefenderUI and DefenderUI Pro both auto update themselves when they are launched, but I think it will be cool to have them in the app store anyway. Thank you!
