Question

I’m using .NET 3.5 and WCF for developing a server-client application. Binding=BasicHttp.
I’m working and deploying the service in a windows 2003 server sp2.

The service in the server is being self-hosted by a console application and in my computer everything works fine. The thing is that when I deploy the server in the computer it should run, it takes EXACTLY 15 seconds to open the serviceHost instance, when it should be milliseconds. I could live with that, but also when this instance receives the first request from a client, it takes EXACTLY 15 seconds to respond, and like this with each new client. After the first request, it takes just milliseconds to respond the following.

I’m not having this problem in my computer and I’ve tried in many others and it’s working fine also. I don’t have the possibility to format the server in which I’m deploying in, so I need some advice about what can be wrong in that particular computer or configuration.
This behavior repeats with ANY service I want to host in that machine, even the basic example in the “WCF service library” template, so for the sake of simplicity I’m working on it while I’m solving this problem.
This is the app.config I’m using in the host app. The rest of the code is exactly the one of the template above mentioned.
Please keep in mind the service is working fine, is the delay that makes the service unusable.

Thanks in advance !

Answer 1

The problem was solved when I found out that it wasn’t installed service pack 1 of .NET 3.5. in the computer I was having problrems. Once I’ve installed it, everything started to run normally without delays.

Thanks everyone for the advices!
Best regards
