It's got incredible - I can only build develop builds with fastbuild enabled (or it simply get's hung on detecting installed packages).
Now I have to unplug/replug my device every 2nd or 3rd build, then clean and rebuild just to get it to build.
If it behaves moderately well, then it insists on installing the shared runtime every single time.
Build cycles take anywhere from 3-5 minutes now, due to not being sure if it will give up half way through for no reason whatsoever or removing shared runtime, reinstalling it.
I see this behaviour in 5.8, 5.9 and 10. I find that 10 is the worst and more often than not simply refuses to deploy.
Anyone else seen these weoful
