System.Net.Http.Json not recognized about interactive HOT 2 OPEN

I've also experienced this issue.

My workaround was to downgrade the Polyglot notebook version to 1.0.456201 which worked as expected.

from interactive.

I'm seeing this issue as well. I wrote an extension method as a work around for ReadFromJsonAsync:

public static async Task<T> ReadJsonAsync<T>(this HttpContent response  ){
			return await response.ReadAsStringAsync().
				ContinueWith<T>(s=>JsonSerializer.Deserialize<T>(s.Result));
		}

from interactive.
