Unlike Microsoft network monitor, Wireshark (Version 3.0.0 (v3.0.0-0-g937e33de) ) always shows DSCP value as CS0 for TCP and CS7 for UDP irrespective of whatever actual value is set.

Wireshark 2.x version & Microsoft network monitor shows the values properly.

How do I see the correct DSCP value using latest Wireshark?

I don't see this. Can you share a capture file showing this? Any public file sharing site would do.

I m not able to upload screen shots as it needs 60 points.

Jaap said "share a capture file", not "share a screenshot of what Wireshark displays for a capture file", and captures can be uploaded to sharing sites such as Dropbox/Google Drive/etc. to make it available.

Or you can report this as a bug on the Wireshark Bugzilla and attach a capture file to the bug report.

This shows UDP packets with both CS7 and EF PHB for me.
