Hi All,
I have created a self hosted wcf service in a win form app. Every thing works fine(the communication)...
Problem: My application starts on system startup, and as soon as my app starts it triggers my wcf service to start "selfHost.Open()"
but the main problem is it hangs up the system. making the application not usable for aroung 20 30 seconds.
Do any of you have a solution.
Thanks in advance

Solution 1

Use all communication part in a separate thread. Don't even play with the idea of doing networking, remoting or WCF without threading.

Comment from OP:
Thanks SA,
I have started the wcf service in saperate thread, but still it hangs the system,
I guess the problem is somewhat related to the system startup, Because it does not hang when I logoff and login the XP.
But the problem only occurs when I restart the system.

If can happen, too. It's just there is no enough information to dig into your problem.

The problem is probably that your network connection isn't ready when you want to connect to your wcf service. Try using a short delay, or try to see if your network connection is set up before you try to connect to your WCF service

Thanks Wannes,
I gone through those articles.
I applied the above said setting in my app.config file but no effects in starting time of my app.

Actually mine is a self hosted wcf service in a win form App. And I am running this application on windows startup. and it takes aroung 50-60 seconds to load the application.

Nitin :(

and if you try to run another application on the startup of your system, does it also takes as much time. Because in that case, maybe you are starting too much applications at the same time and is that the reason why your system is running slow.

Wannes Geysen
No none other app are getting started on my pc.
And even if i start any other app it does not take much time.
Also if I comment the code to start the wCf service, It does not take much time.

Also One more important thing just came to my notice that my application was previously on .net framework 3.5 i just migrated to 4.0, and problem has just started after the 4.0 migration. do you now have any idea.. :)

Thanks again,

but le me be clear that I am not connecting to a wcf service. I am trying to start a one.

And I tried that Before trying to start it network connection has acquired IP. I have written below code to start the service.

VB

 Dim baseAddress As Uri = New Uri("http://localhost:8080/me/myService")

 Dim selfHost As New ServiceHost(GetType(WCFService), baseAddress)
 
 selfHost.AddServiceEndpoint(GetType(MyContract.IServerManager), New WSHttpBinding(SecurityMode.None), "WCFService")

 Dim smb As New ServiceMetadataBehavior()
            smb.HttpGetEnabled = True
            selfHost.Description.Behaviors.Add(smb)
selfHost.Open()

I guess you use some services that you wcf service begin

I don't know the wcf service use what can stop it,someone have the same issue

http://stackoverflow.com/questions/1234188/windows-service-hung-on-starting-during-boot

They use DependOnService attribute to add dependency

It works for me
