i am facing some problems with connecting xcode client with c sharp server. i am running mac in a virtual machine and getting this output
014-03-19 10:30:12.468 FYPSeconf[761:c07] Tcp Client Initialise

following is the code that i am using.

- (void)TcpClientInitialise
{
NSLog(@"Tcp Client Initialise");

CFReadStreamRef readStream;
CFWriteStreamRef writeStream;


CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)@"localhost", 9050, &readStream, &writeStream);

InputStream = (__bridge NSInputStream *)readStream;
OutputStream = (__bridge NSOutputStream *)writeStream;

[InputStream setDelegate:self];
[OutputStream setDelegate:self];

[InputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[OutputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];

[InputStream open];
[OutputStream open];
}

and for receiving stream

- (void)stream:(NSStream *)theStream handleEvent:(NSStreamEvent)StreamEvent
{

    switch (StreamEvent)
    {
        case NSStreamEventOpenCompleted:
            NSLog(@"TCP Client - Stream opened");
            break;

        case NSStreamEventHasBytesAvailable:
            if (theStream == InputStream)
            {
                uint8_t buffer[1024];
                int len;

                while ([InputStream hasBytesAvailable])
                {
                    len = [InputStream read:buffer maxLength:sizeof(buffer)];
                    if (len > 0)
                    {
                        NSString *output = [[NSString alloc] initWithBytes:buffer length:len encoding:NSASCIIStringEncoding];

                        if (nil != output)
                        {
                            NSLog(@"TCP Client - Server sent: %@", output);
                        }

                        //if (ActualOutputBytes >= ChunkToSendLength)
