On Build 2018 there are some Sesions around MSIX. Which is the Evolution of App-V. Just to make Clear - if you are using App-V now, your Investment is save and will be carry on. Plus with MSIX and using App-V now you are ahead of the curve.
I am, as a long term App-V Engineer very happy to see that -finally - there is a way to get rid of MSI and have a real modern way of deploying Applications.
If you look for some sessions ( I think there will be recordings as well) go to https://mybuild.microsoft.com/sessions and Search for MSIX.
