Answer by haldo for How can I deserialize JSON to a simple Dictionary in ASP.NET?

System.Text.Json

This can now be done using System.Text.Json which is built-in to .NET Core 3.0. It's now possible to deserialize JSON without using third-party libraries.

var json = @"{""key1"":""value1"",""key2"":""value2""}";var values = JsonSerializer.Deserialize<Dictionary<string, string>>(json);

Also available in NuGet package System.Text.Json if using .NET Standard or .NET Framework.
