Some samples of SVC I have seen all have some additional methods that they call, like Service.svc/GetData and calling directly Service.svc I will get the standard response:
You have created a service.
To test this service, you will need to create a client and use it to call the service.
Can anyone point me to the correct documentation or even better - to a simple sample in C# on how to create SVC page that can be accessed directly and that would return some XML text?
You can go for REST Service.
Also, can use Web API. http://www.asp.net/web-api
