[Mono-list] NotImplemented error creating WCF ServiceHost

[Atsushi Eno]

Exactly, the exception is thrown from WCF itself. And that exception 
tells you that you cannot use the feature unless someone implements it.

Though it would be almost impossible to find out which configuration 
part causes the exception unless you are very familiar with 
configuration settings or you give up using configuration. It is also 
likely you are using unsupported feature anyways.
