The service class is compiled into one of the referenced assemblies. The service used is FirstWcfService.Service1 as defined in the svc file:

Service="FirstWcfService.Service1"

CodeBehind only matters to the tooling (Visual Studio). It doesn’t matter at runtime, where the system will only look at what types are declared and used.
