WCF Service class static constructor called in every call -

i have service class implementing contract follows:

interface icontractfoo {     void foo(); }  class servicefoo() : icontractfoo {     public static servicefoo()     {         log("static constructor called");     }      void foo()     {         log("foo called");     }  } 

what finiding each time foo api called, static constructor gets called. so, log looks -

static constructor called
foo called
static constructor called
foo called

this should not happening since static constructor. idea going wrong?

thanks help

by default, wcf services use "per-call" model. don't think marking constructor static change behavior. can change using servicebehavior attribute or changing servicebehavior settings in web.config file associated service.

here couple articles might decide model appropriate services:
