How to make TCP enabled on lan - wpf

Question

I have written a code for my WPF App to use WCF, wcf is running as Windows service, I want the program wpf to run on client machines. I installed WPF app on PC along with the service and sql server, it is working fine in there. However, when I installed the wpf client on another PC, the client WPF is not able to connect to the server. I mean the WCF windows service is not support for lan usage, however I designed it for this intention only. Could you please check my code and tell me where I have gone wrong please.
WPF App code:

Looking forward for the needfull. Thank you.

Answer 1

It appears that all of your service addresses are set to localhost, in both the service and the client config files. Localhost always refers to the machine the program is running on.
You'll need to use the correct machine name for the service and reference it in the client.
For example, say your service is hosted on a machine on the network with the following address - myservicebox:8732. The service's config file would look like this:
<service name="WorkMateWCF.WCFLogin">
<endpoint address="" binding="netTcpBinding" bindingConfiguration=""
contract="WorkMateWCF.IWCFLogin">
<identity>
<dns value="myservicebox" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexTcpBinding" bindingConfiguration=""
contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="net.tcp://myservicbox:8732/WCFLogin" />
</baseAddresses>
</host>
</service>
You would then reference net.tcp://myservicebox:8732/WCFLogin in your client(s) that wish to utilize the service.
Also, note that your service (based on your posted config file) will be using the default values for the specified bindings, which may cause problems for you if you need different values (like bigger message size, etc).
Your client config will use the bindings you've set up as you assign them to the client endpoints via the bindingConfiguration attribute.
Not necessarily a problem in your case (and it looks like you're using the default values on the client anyway, at a quick glance), but something to be aware of.

I later checked the event logs and the issue was with the time on binding and I changed it to 00:10:00 and it seems to work, but this time I landed on a new error and it does not relate to this question.
