      Where can I find the batch file that you used in your demo?

      You can create your batch file, here are the content of that batch file
      @if %_echo%!==! echo off

      set UserOptions=-BufferSize 1024 -MinBuffers 32 -MaxBuffers 32 -Buffering
      set KernelOptions=-BufferSize 1024 -MinBuffers 64 -MaxBuffers 64 -Buffering

      xperf -start xaml_user -on "Microsoft-Windows-XAML::5"+perftrack %UserOptions%
      xperf -on base+cswitch %KernelOptions%

      xperf -m BeginTrace
      echo Event listeners started, run desired scenario then press any key
      pause
      xperf -m EndTrace

      echo stopping xaml_kernel...
      xperf -flush -f xaml_kernel.etl
      xperf -stop

      echo stopping xaml_user...
      xperf -flush xaml_user -f xaml_user.etl
      xperf -stop xaml_user


      echo merging to xaml_merged.etl...
      xperf -merge xaml_user.etl xaml_kernel.etl xaml_merged.etl

      This is a great session Kiran, xperf, WPA and DebugSettings are great tools for XAML Windows store app developers.

      Does anyone else have problems finding the XAML events discussed in the video? I used the batch file Kiran pasted above, but have no XAML events when I open the logfiles it makes in WPA.

      I wrote an step-by-step article based on Kiran's presentation which might help your find the xaml startup events.
