IService1 is an interface.  ServiceHost doesn't want that, it wants the class that implements the interface.  Try this:

ServiceHost host = new ServiceHost(typeof(Service1));

then added this
<identity>
            <dns value="localhost" />
to app.config's endpoints,

but later had this :

There is already a listener on IP endpoint 0.0.0.0:8731.  Make sure that you are not trying to use this endpoint multiple times in your application and that there are no other applications listening on this endpoint.

It looks like there is a configuration for named pipes, but ultimately it is using HTTPS.  Describe how you want to access this service so we can configure the correct binding and endpoint.

doramail05,
The reason that you now have "0" open questions is that a variety of Cleanup Volunteers and Moderators have closed your questions for you - not because of any action that you took.

I am going to TEMPORARILY restore your ability to ask new questions but you need to understand clearly that it is your responsibility to manage the questions you post.

Please review the information below about what are the appropriate actions to take for your questions:

a) Respond to all Expert comments, even if it is to say "sorry, but that doesn't work". Allow the Experts 24 hours to reply. If you receive no further responses, either delete and repost the question or use the "Request Attention" option to ask the Moderators for assistance.

b) If you solved the question yourself, post your self-solution in a new comment, then close the question using the Accept as Solution option beside *your* comment. This will start the auto-close procedure.

c) If one or more Expert comments provided a solution you have already tested and confirmed, use the Accept as Solution or Accept Multiple Solutions options to award the points to a single Expert or split them accordingly.

d) If no Expert provided a solution or your question does not seem to be going anywhere, you may request deletion using the Delete Question link/button.
