After my previous post where I showed you how you can eliminate the .SVC extension from your URI someone asked me another good question.
When I add the route I can access the service from the route and the path to the SVC file. Can I block the path to the SVC file from accessing the service?
Absolutely – all you have to do is get rid of the .SVC file. But be careful when you do! If you delete the .svc file VS2010 will also delete the code-behind file.
VS2010 treats the file where your service code lives as code-behind so it offers you a limited set of options for dealing with it.
The best thing to do is to open the file and save it without the .svc extension. In this case I saved it as Conference.cs.
Now you can delete the .SVC file this will prevent it from being used as a path to access the service
With the .SVC file gone only the URI from the route will be able to access your service.
