Proper implementation of a bidirectional dictionary, also known as "BiMap" or "Two-way dictionary", for .NET Standard 2.0.
Example of usage

{
["Italy"] = "Rome",
["India"] = "New Delhi",

};
Console.Write(countryCapitalDictionary["Italy"]); // "Rome"
Console.Write(countryCapitalDictionary.Inverse["Rome"]); // "Italy"

using System.Collections.ObjectModel;
var readOnlyDictionary = new ReadOnlyBidirectionalDictionary<string, string>(dictionary);
