POAny NIO frameworks for .NET?

Body
copied!<p>Are there any non-blocking IO frameworks for .NET? </p> <p>I am looking for something similar to what <a href="http://mina.apache.org/" rel="noreferrer">Apache Mina</a> and <a href="http://www.jboss.org/netty" rel="noreferrer">JBoss Netty</a> provides for Java: a framework for implementing highly scalable servers - not just the low-level support that the .NET framework provides.</p> <p><strong>EDIT:</strong> To better explain what I would like to see, here is a basic example of what you can do with Mina:</p> <p>In Mina I can implement a ProtocolDecoder like this:</p> <pre><code>public class SimpleDecoder extends CumulativeProtocolDecoder { protected boolean doDecode(IoSession session, IoBuffer in, ProtocolDecoderOutput out) throws Exception { if (in.remaining() < 4) return false; int length = in.getInt(); if(in.remaining() < 4 + length) return false; Command command = new Command(in.asInputStream()); out.write(command); } } </code></pre> <p>And a CommandHandler like this:</p> <pre><code>public abstract class CommandHandler extends IoHandlerAdapter{ public void messageReceived(IoSession session, Object message) throws IOException, CloneNotSupportedException { Command command = (Command) message; // Handle command. Probably by putting it in a workqueue. } } </code></pre> <p>If I start the server by calling</p> <pre><code>CommandHandler handler = new CommandHandler(); NioSocketAcceptor acceptor = new NioSocketAcceptor(); acceptor.getFilterChain().addLast("protocol", new ProtocolCodecFilter(new SimpleDecoder(false))); acceptor.setLocalAddress(new InetSocketAddress(port)); acceptor.setHandler(handler); acceptor.bind(); </code></pre> <p>I will get a non-blocking server.</p> <p>It will run a single (or at least just a few) threads, cycling through all incoming connections, gathering data from the sockets, and call <code>SimpleDecoder.doDecode()</code> to see if it has a complete command on the connection. Then it will pass the command to <code>CommandHandler.messageReceived()</code>, and I can take over the processing.</p>
