edit:

i've looked into: custom certificate validation in wcf service , authentication of clientcertificate element , how to: create service employs custom certificate validator , x.509 certificate validator , none of links describe issue having.

compilation error message:

interface code:

imports system.servicemodel imports system.security.permissions  namespace myproject     ' note: can use "rename" command on context menu change interface name "imyprojectwcf" in both code , config file together.     <servicecontract([namespace]:="myproject")> _     public interface imyprojectwcf         <operationcontract()> _         function helloworld() string     end interface end namespace 

edit 2 (with fix):

insert default constructor cert validator class:

    public sub new()         me.new("cn=yourcertificate here")     end sub 

and had figure out project name of website is, app_code, gets compiled bunch of other pages 1 dll, app_code.dll. final line in web.config looks this:

<authentication certificatevalidationmode="custom" customcertificatevalidatortype="myproject.myx509certificatevalidator, app_code"/> 

so there no compiled errors , wsdl. thank :)

i think have change

customcertificatevalidatortype = "myproject.myx509certificatevalidator, service"/>

to

customcertificatevalidatortype = "myproject.myx509certificatevalidator, myproject"/>

because 'service' it's not in namespace. maybe pasting msdn, have think msdn wcf demo projects ('101 samples'), used called 'service'.
