If you already created interfaces you need to implement those interfaces. Just create new web service and add interface that you generated so that it inherits that interface. Visual Studio can automatically generate stubs for every method in interface.
Mark them with WebMethod attribute and put some code that will return some test data/results.
All you need to do is create a class that inherits from the interface that WSDL. EXE has generated, and then implement the methods from the interface.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
