Question 1

How to enable TLS encryption with sockets-for-pcl?

Accepted Answer

Pass true to the useTls parameter in TcpSocketClient.ConnectAsync. This enables server certificate authentication for secure TCP connections, as shown in the README's TLS support section.

Question 2

Sockets-for-pcl vs System.Net.Sockets for cross-platform apps?

Accepted Answer

Sockets-for-pcl abstracts platform differences for Xamarin and Windows, allowing code sharing in PCLs. System.Net.Sockets is platform-specific and requires separate implementations for each target, making sockets-for-pcl better for multi-platform projects.

Question 3

Does sockets-for-pcl support UDP multicast on all platforms?

Accepted Answer

Yes, via UdpSocketMulticastClient, but interface binding has limitations on Windows Phone 8.0, and multicast behavior may vary by platform, so testing is advised.

Question 4

How to handle socket disconnections and errors in sockets-for-pcl?

Accepted Answer

The library provides low-level events like MessageReceived for UDP, but developers must implement their own error handling and reconnection logic, as it doesn't include built-in reliability features.

Question 5

Can I use sockets-for-pcl for building a real-time chat application?

Accepted Answer

Yes, it's suitable for peer-to-peer communications, but you'll need to add message framing, retry logic, and possibly integrate with sockethelpers-for-pcl for higher-level abstractions like hub-style messaging.

Question 6

What are the manifest requirements for sockets-for-pcl on Windows Phone?

Accepted Answer

You need appropriate capabilities in the app manifest, such as privateNetworkClientServer, internetClient, or internetClientServer, depending on whether you're listening or sending, as noted in the platform considerations.
