!heap -p command is not work in windbg version 22621

Stephen_Wang

!heap -p -a command is not working after I upgrade to windows SDK 22621, windbg version is 10.0.22621.755 AMD64.

0:030> !exts.heap -p -a 00000291B5D8CFB0 
**********************************************

the `!heap -p' commands in exts.dll have been replaced
with equivalent commands in ext.dll.
If your are in a KD session, use `!ext.heap -p`
**********************************************
0:030> !ext.heap -p -a 00000291B5D8CFB0 

I have turned on Page Heap and user mode stack trace database，but !ext.heap -p -a output nothing, and even !ext.heap -s has not output, !exts.heap -s is working.

0:030> !ext.heap -s
0:030> !exts.heap -s

0:030> .extmatch /e ext* heap
!ext.heap
!exts.heap

Which of these two !heap command should I use? How to make !ext.heap works?
Thanks.

No idea, don't do user mode debugging/developement...However, have you tried the latest version of the WinDbg Preview/v.Next? That should be using a newer version of the debugger engine than the "classic" version:
