Hi,

For creating a Silverlight chat application I can recommend the Ozeki VoIP SIP SDK. For sample source codes check this: www.voip-sip-sdk.com/p_257-silverlight-video-chat-example-voip.html

The support team is also responsive so you can make your project even faster with the help of them.

disregard, I finally figured it out that I had to add the IP Address of the server into client local intranet zone. Somehow the server uses IPv6 and wasn't working with localhost. By adding the IP address, it stopped prompting for username password. I will have to check with Admin guys as to why this is the case. I also had to put the servername in the client config file.

Setting the server/client config to either localhost or the servername keeps prompting me for username and password. Do I need to do something else in IIS? I only have windows authentication enabled. I tried setting anonymous also, but the window security is still prompting. What is weird is, when running in VS, browser it also prompts me for user name and password when I run it. any ideas? this is only happening with net.tcp apps.

can i just have net.tcp as the protocol enabled on the service in IIS and not http. when i remove http it throws an error saying that the service could not be activated.

You can find a working sample and explanation here:

I have a working silverlight application that talks to a self-hosting TCP service wpf application.

This is the picture: intranet with n silverlight clients and 1 self-hosting TCP service wpf application that works as a server. Everything is wonderful if the clients are running on a windows machine, but I can't make the service work on a MacBook Pro connected in the very same intranet. Everything looks fine:

I can ping the Macbook from the server machine, and I can ping back the server machine from the macbook. I can see the shared folders of the server machine from the macbook, nonetheless I can't see anything coming back from the wcf via net.tcp service.

My question is:

Is it possible at all a similar scenario (an intranet with Mac's and Pc's living together and using the same WCF service via net.tcp)?.

Do you have a hint of what could make it work?

Best Regards

Roberto Dalmonte

Hi Roberto.

You can configure WCF to work with two or more different bindings. You can specify different bindings for same WCF service in config file so you can have one binding for WPF and another for Silverlight and use same WCF service with no changes in code of WCF service.

Thanks

Cross platform (Windows & Mac) WCF-Silverlight app

Roberto Dalmonte — Mon, 22 Nov 2010 11:38:45 GMT

Hi Radenko,
my goal is to develop a cross-platform INTRANET application with the following components:
1) WCF Host running on WPF Windows application on a windows machine
2) Silverlight client hosted indifferently on a windows or mac machine.

At the moment I have a working application with the following component:
1) WCF Host running on WPF Windows application on a windows machine
2) WPF client running on windows machine

The WCF host is configured this way:

String baseAddress = string.Format("net.tcp://localhost:{0}/ArchiveEndpoint", port);
              NetTcpBinding binding = new NetTcpBinding(SecurityMode.None);
              XmlDictionaryReaderQuotas quota = new XmlDictionaryReaderQuotas();
              quota.MaxStringContentLength = quota.MaxArrayLength = quota.MaxBytesPerRead = binding.MaxBufferSize = Int32.MaxValue;
              binding.MaxReceivedMessageSize = Int32.MaxValue;
              binding.ReaderQuotas = quota;
              binding.TransferMode = TransferMode.Streamed;
              serviceHost = new ServiceHost(typeof(DataService));
              serviceHost.AddServiceEndpoint(typeof(IDataContract), binding, baseAddress);
              serviceHost.Opened += new EventHandler(OnServiceOpened);
              serviceHost.Open();

My question:
is it possible to configure the silverlight client to run against my existing WCF server? This way I might have both WPF clients running on windows machine, Silverlight clients running on either windows or mac machines.
Thanks
Roberto Dalmonte

Hi Mark and Eugene,

I don't know, I also couldn't find it. Probably it is not available for Silverlight.

RE: WCF NET.TCP Protocol in Silverlight 4

Mark — Fri, 16 Apr 2010 21:47:28 GMT

I don't see it, either. Anybody?

Would anybody please tell me into which assempbly NetTcpBinding is included in VS2010 RTM? I expected to find it in System.ServiceModel but looks like it's not there....

You said you have to use IIS to provide a WCF service, but this is not necessary. WCF can run without IIS if you are using TCP as the protocol. On the other hand, if your using WCF RIA you will need IIS from what I can tell so far. I'm guessing there's a way to configure it to not require IIS but I have not had time to research further.

This is great! another cool additional features of Silverlight! Though in terms of performance and speed without the hassle of ISS configuration and the like, I still consider using Silverlight implementation of the Berkely Socket Interface.

RE: WCF NET.TCP Protocol in Silverlight 4

RadenkoZec — Sun, 03 Jan 2010 11:38:35 GMT

When using TCP from Silverlight 4 we need to use port in specific range from 4502-4534 because Silverlight TCP is build on top of sockets and has same network security restrictions. See http://msdn.microsoft.com/en-us/library/cc645032(VS.95).aspx

So on client side when we connect to Silverlight 4 app that uses TCP we must connect through some of these ports 4502-4534. If client has firewall maybe these ports are disabled in firewall by default or when we connect firewall it will ask to add exception. We can't assume that client will click yes to add exception in firewall for our app.

I hope this helps.

Bryan Livingston — Sun, 03 Jan 2010 04:12:39 GMT

I don't understand the intranet and firewall requirements.

If I build and deploy a WCF server that uses the required port range, and then deploy on a public web site a silverlight 4 app that talks to the WCF server, then are you saying that no one will be able to hit the service without messing with their firewall?

Is it their windows firewall on their own computer or is it their home routers or does it have something to do with NAT (Network Address Translation)? Why wouldn't the silverlight app be able to initiate a duplex tcp connection with the server like anything else?
