I'm trying to implement exception handling in a WCF service. I want this exception to be thrown to the client so it can be logged and handled.

I don't know if the code I've written is right or wrong. This only gets me "faultexception was unhandled by user code" How should i solve so i can handle my the exception in client?

Code in WCF-Service:

try
{

}
catch (FaultException fex)
{
    throw fex;
}
catch (Exception ex)
{
    throw ex;
}

Code in client:

try
{

}
catch (FaultException fex)
{
    Logger.AddExceptionToDb(fex);
}
catch (Exception ex)
{
    Logger.AddExceptionToDb(ex);
}

You should apply [FaultContract(YourFaultClass)] attribute to method which will throw fault exceptions.

   [OperationContract]
   [FaultContract(typeof(YourFaultClass))]
   void Foo(int par1);

How to throw it from service:

throw new FaultException<YourFaultClass>(new YourFaultClass());
