System.Text.Json failes to serialize System.Net.IPNetwork and System.Net.IPAddress objects #118725
Closed as not planned
Description
Description
I was trying to serialize a System.Net.IPNetwork and was consistently getting some exceptions. After debugging a bit more, I found out that the problem is inside System.Text.Json itself.
This erros happens for System.Net.IPAddress objects too.
Reproduction Steps
Check this snipped from F#:
System.Net.IPNetwork.Parse("127.0.0.1/32")
|> System.Text.Json.JsonSerializer.SerializeToUtf8BytesYou can run it using the FSI.
The result I'm getting:
Expected behavior
Correctly serialize the System.Net.IPNetwork and System.Net.IPAddress objects.
Actual behavior
Throws this exception:
System.Net.Sockets.SocketException (95): Operation not supported
at System.Net.IPAddress.ThrowSocketOperationNotSupported()
at System.Net.IPAddress.get_ScopeId()

No response
Known Workarounds
Transforming this IPNetwork, or System.Net.IPAddress objects into strings works.
Configuration
- .NET SDK 9.0.101
- Ubuntu 24.04
- x86
Other information
I'd check the exception stack information.
