How can I deserialize JSON to a simple Dictionary in ASP.NET?

Question

I have a simple key/value list in JSON being sent back to ASP.NET via POST. Example:

{ \"key1\": \"value1\", \"key2\": \"value2\"}

Answer 1

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>(json);

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