3 months ago Workaround:
pc.onicecandidate += (c) =>
{
pc.addLocalIceCandidate(c);
Console.WriteLine(c);
if (pc.localDescription != null)
{
if (pc.localDescription.sdp.IceCandidates == null)
pc.localDescription.sdp.IceCandidates = new List<String>();
if (c != null)
pc.localDescription.sdp.IceCandidates.Add(c.ToString());
}
};
First, thanks for creating this software. I have encountered a problem with ICE candidates.
Usual flow: Create RTCPeerConnection with ICE servers (STUN/TURN) Create a DataChannel dc using createDataChannel() offer = RTCPeerConnection.createOffer(null) RTCPeerConnection.setLocalDescription(offer)
The logs indicate that the candidates were gathered.

However, the last part is the pc.localDescription. The candidates do not appear here. So maybe I had to manually add them:
pc.onicecandidate += (c) => { pc.addLocalIceCandidate(c); Console.WriteLine(c); };
No luck, still pc.localDescription is the same as if there are no candidates except host (new candidates were not added). Is there anything I am missing? Are things working as intended? For JS (Firefox/Chrome), wrtc and WebRTC-rs, I did not have to do anything special to have this working. Is there any other way to get the up-to-date
localDescription?Thank you for your time.
