In Visual Studio 2017 using 18.104.22.168: when I add XamlCompilation for the entire assembly, visual studio sees it as non-user code. When trying to debug and stepping into it, it says 'Step into: Stepping over non-user code'.
As soon as I comment out the XamlCompilation attribute, debugging works again for the assembly.
Apparently it is happening also in Xamarin Studio: https://forums.xamarin.com/discussion/89948/xaml-compilation-at-assembly-level-cause-debugger-break-point-not-fire?
That probably indicates that VS can't find the .pdb associated.
Could you check that the .pdb file is present and up-to-date (has the same timestamp as the assembly) ?
Also, you should check if it works better with 22.214.171.124, as that version contains an an enhancement for portable pub support.
It looks like version 126.96.36.199 solves this bug. After upgrading it seems to be working fine now.
