after updating Microsoft.Xaml.Behaviors.Uwp.Managed
to version 1.1.0
Template10 app doesn't build with error:
CS0012
The type 'ActionCollection' is defined in an assembly that is not referenced.
You must add a reference assembly.
Also all Apps built with template10 including blank/hamburger/minimal templates (latest Template10 version 1.1.5) without any code added fail Windows app certification kit App prelaunch test.
See https://github.com/Windows-XAML/Template10/issues/700 - Jerry thinks that something is wrong with 1.1.0, so use 1.0.3 for now.
