How to debug source code?

[Kation]

I'm building Xamarin.Forms myself and want to debug into it.
Create a breakpoint as usually.
When application running to a breakpoint, it was paused but current call stack is not at breakpoint.
It's showing code from current solution' project where first in call stack.
All Xamarin Forms method in call stack are disabled.
Both android and ios have the same problem.

I build package by .create-nuget.bat.

It was correct in last few months before I pull source code from git some day.
