I've been having this issue regularly for the past 6 months or so, and I keep hoping it gets fixed with every new version but it keeps reoccurring. Every time I type out Vector3 I expect it to suggest the obvious type of "UnityEngine.Vector3" but Rider always suggests 'System.Numerics.Vector3' as the top pick. My files always have "using UnityEngine" so why on earth would it suggest a brand new type to import? Have I misconfigured my project somehow?
Also, maybe this is another configuration issue, but another common frustration is when I'm trying to create a new List<T> the "new" auto-complete suggestion can take 3-4 seconds to show up, so I end up having to type out the entire name of the type manually which kind of sucks. Definitely makes me reconsider why I'm paying for Rider.
Any suggestions on fixing either of those would be great.
