I'm trying to return a IDictionary<int,int> (created with dict tuplist) from F# to C#, but it says that I must include a reference to FSharp.Core because of System.Collections.IStructuralEquatable.
I've tried returning a Dictionary<_,_>(dict tuplist), but that doesn't make any difference.
I even tried Dictionary<_,_>(dict tuplist, HashIdentity.Reference), but that says that int is a struct...
