FreddiChat is a simple chat client and server solution written in C# using WCF (client, server) and WPF (client). It uses NetNamedPipeBinding, NetTcpBinding or WSDualHttpBinding for connections. It's minimalistic in its looks and its interaction patterns are rather similar to mIRC or other channel based clients. FreddiChat however only provides one channel per server.

• Connect to any server using desired name (type /connect user host)
• Broadcast messages to all users
• Whisper message to specific user (double-click desired name or type /w user)
• Reply to last received whisper (type /r )
• Links are automatically marked up and clickable
• History of previous commands or messages (use up and down arrow keys)
• Clear chat history (type /clear)
• Disconnect from server (type /disconnect)
• Quit at any time (type /quit)

The source consists of two projects.

• FreddiChatClient is a WPF application, which provides the user with an interface to connect to servers and chat with other users.
• FreddiChatServer is a console application, which provides a chat service. It displays relevant calls to and operations of the server, providing very limited interaction and configuration.

Follow the steps below to build the server and the client.

1. Open FreddiChat.sln in Visual Studio
2. Select Build Solution to build the server and the client
3. Browse to FreddiChat\ChatServer\bin\Debug and execute FreddieChatServer.exe to start the server
   • Select net.pipe as protocol when prompted
   • Select localhost as hostname when prompted
4. Browse to FreddiChat\ChatClient\bin\Debug and execute FreddieChatClient.exe to start a client
   • Type /connect Anonymous net.pipe://localhost to connect

• Named Pipe using the NetNamedPipeBinding, e.g. net.pipe://localhost/FreddiChat/
• TCP using the NetTcpBinding, e.g. net.tcp://localhost/FreddiChat/
• HTTP using the WSDualHttpBinding (a port must be specified), e.g. http://localhost:8080/FreddiChat/

Warning: No security is applied for connections.

Security mode None is used. Anyone can access the service and messages are not encrypted.

The service client is generated using the ServiceModel Metadata Utility Tool (svcutil.exe). It must be regenerated when changing the service contracts.

Follow the steps below to regenerate the service client.

1. Open FreddiChat.sln in Visual Studio
2. Right-click the FreddiChatServer project and select Build to build the server
3. Browse to FreddiChat\ChatServer\bin\Debug and execute FreddieChatServer.exe to start the server
   • Select net.pipe as protocol when prompted
   • Select localhost as hostname when prompted
4. Start Developer Command Prompt for Visual Studio
5. Execute svcutil.exe /language:cs /noConfig /namespace:*,FreddiChatClient.Communications /out:FreddiChat\ChatClient\Communications\GeneratedChatServiceClient.cs net.pipe://localhost/FreddiChat/mex to regenerate the service client

To prevent the Visual Studio debugger from breaking on LoadFromContext occurred and NotMarshalable occurred, disable the Enable UI Debugging Tools for XAML option in Tools > Options > Debugging > General.
