Hello @Hunter K,
Welcome to Microsoft Q&A forum.
I don’t think you are doing something wrong. I notice that there are some similar/same issues reported before:
Unable to load dll microsoft.data.sqlclient.SNI.arm64.dll
Both are currently under investigation, so probably, it’s an issue about VS ARM64 data source connection.
I may suggest you try the workaround/suggestion that shared by Andrew Hills here, upvote the thread there, follow up that ticket and wait for the latest information.
Sincerely,
Tianyu
