class accumulate tests/console nonetheless asp.net application

i have rudimentary interface:

public interface ivisitorslogcontroller  
{
    list<visitorslog> getvisitorslog();
    int getuniquesubscriberscount();
    int getvisitorscount();
    twine getvisitorssummary();
}

the category visitorslogcontroller implements interface.

from console concentration testfixture - problem - console/test tie accumulate perfectly.

however, an asp.net web site (not application) same fortitude formula code behind

private ivisitorslogcontroller ctl;

protected int getuniquememberscount()
{
    ctl = new visitorslogcontroller();
    relapse ctl.getuniquesubscriberscount();        
}

the compiler throws exception:

error 1 'websitebusinessrules.interfaces.ivisitorslogcontroller'
does enclose construction for
'getuniquesubscriberscount' no
progression method
'getuniquesubscriberscount' accepting
initial justification type
'websitebusinessrules.interfaces.ivisitorslogcontroller'
found (are blank a

reference?)

yet formula same file:

  stable stationary int getvisitorscount()
{
    relapse visitorslogcontroller.instance.getvisitorscount(datetime.today);
}

the compiler compiles lines but complaining. fact i supplement anything new interface compiler complains perplexing accumulate asp.net page.

it can't blank controlling gauge public anxiety differently both methods fail.

this pulling me nuts!

any thoughts please?

thanks,
