SSMS 21/22 Error Upload BACPAC file to Azure Storage
This is indeed a bug in SSMS.
The suggested workaround is not helpful, however it point you in the right direction, in case you are blocked and you don't want to wait for a release of SSMS with the fix I'm preparing.
You just need to download the package from https://www.nuget.org/packages/System.IO.Hashing/6.0.0 rename it to .zip, unzip it and grab trhe System.IO.Hashing.dll you find under the lib/net461 folder. Copy it to the <SSMS_Install_Path>\Common7\IDE of your machine... Close and reopen SSMS and you should be good to go.
For reference, the easiest way to get in touch with us (SSMS Product Team and the rest of the SSMS community is to report the issue directly via the SSMS UI: just use the menu "Help | Send Feedback | Report a Problem" and fill out the form. Doing so would allow the SSMS community to see the issue, upvote it and be notified when a fix is available. Keep that in mind for the future!
Thank you! it works
Same bug existed in V21, don't understand why still not fixed in V22
I will report the bug using Help menu in the future
Thanks

Simply because.... this is not a a forum we (SSMS Team) check for issues reported by users.
For that reason, it was missed.
I fixed it in our mainline branch, so you should expect the change in SSMS 22.x "soon" (either the next update or the one after that)
