It runs good in LINQPad 7, but it prompts following error when compiling in LINQPad 8.0.18:

Method not found: 'System.Net.Http.Json.JsonContent System.Net.Http.Json.JsonContent.Create(!!0, System.Net.Http.Headers.MediaTypeHeaderValue, System.Text.Json.JsonSerializerOptions)'.

Please check, this should be a issue.
