Hi IT Quest,
In your scenario, I see that you have hosted your WCF Service on the WPF application and it throws exception from WPF application, so in my mind, the WPF does not work well when hosting the WCF Service, please try to do a test by using the WcfTestClient(https://msdn.microsoft.com/en-us/library/bb552364(v=vs.110).aspx)
to see if your WCF Service works well.
The following article show us how to host a WCF service using WPF, please try to check it:
https://soumya.wordpress.com/2010/05/26/wcf-simplified-part-7-hosting-a-wcf-service-using-wpf/ .
Please also try to enable the WCF tracing to help find the root cause.

Besides, if the problem still exist, it will better if you can try to post a simple reproduce project in here.
