Aspnetcore: [Blazor] Allow passing of JSON options in PostJsonAsync extension

[mrpmorris]

Microsoft.AspNetCore.Components.HttpClientJsonExtensions always uses an internal set of options that cannot be accessed by a Blazor app.

Please add an additional overload that lets us pass the JSON serialization options to use if we don't want to use the default options.

Thanks for contacting us.
@terrajobst can you please point out to the issue tracking the HttpClient extensions support for System.Text.Json? Thanks!

I don't think we have one yet (there is an internal DevOps item though), so I just filed this: https://github.com/dotnet/runtime/issues/32937
