[API Proposal]: JsonSerializerOptions.GetTypeInfo<T> #118468
Description
Background and motivation
There's already a GetTypeInfo method that takes a System.Type, but a really common case is to downcast to the generic version. This API makes it simple to perform the same operation without introducing potential errors.
API Proposal
namespace System.Text.Json;
public static class JsonSerializerOptionsExtensions
{
public static System.Text.Json.Serialization.Metadata.JsonTypeInfo<T> GetTypeInfo<T>(this JsonSerializerOptions options) { throw null; }
}API Usage
See, for example,
// Old use
var info = (JsonTypeInfo<string>)options.GetTypeInfo(typeof(string));
// New use
var info = options.GetTypeInfo<string>();Alternative Designs
