System.Net.Http.Json not recognized

[Expecho]

Describe the bug

After loading System.Net.Http.Json the assembly is not loaded:

#r "nuget:System.Net.Http.Json"
using System.Net.Http.Json;

results in

The type or namespace name 'Json' does not exist in the namespace 'System.Net.Http' (are you missing an assembly reference?)

This happened as soon as I installed the latest version of Polyglot Notebooks in VS code requiring .Net 8.

Seems the same as this issue

Please complete the following:

Which version of .NET Interactive are you using? (In a notebook, run the #!about magic command. ):

• OS
  • [x] Windows 11
  • [ ] Windows 10
  • [ ] macOS
  • [ ] Linux (Please specify distro)
  • [ ] iOS
  • [ ] Android
• Browser

I've also experienced this issue.

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

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));
		}

any news about this?

[jonsequitur]

This doesn't work because System.Text.Json.Http is a framework assembly. If you use #r without the nuget prefix it will work:

#r "System.Net.Http.Json"
using System.Net.Http.Json;
