Close of Build

I am really looking forward to the bits for project centennial to be released. Has there been a beta release, if so is there a place where I can pick these up along with the documentation.
Extensions can be either via JavaScript or an app service. In terms of IPC then yes there are limitations and that's something we are working on for the next release. Right now the basic concept is that we are trying to keep IPC simple since it's notoriously complex/error prone to get right.
Loading in proc assemblies/dlls gets great perf but also has significant app reliability problems. If the assembly/dll crashes then so does your app. That's obviously a challenge for loading javascript too. If you're loading in proc then being able to update/service the extension becomes almost impossible
you can get the bits for centennial now https://aka.ms/desktopbridge has all the details
