Estou tentando chamar um webservice da minha máquina local. Mas recebo os seguintes erros no console do Chrome:
http://www.test.com/service.svc/api/?cid=1 405 (Method Not Allowed) XMLHttpRequest cannot load http://www.test.com/service.svc/api/?cid=1.<br>Origin http://localhost is not allowed by Access-Control-Allow-Origin.

Meu URL de teste local é:http://localhost/welcome/html/index.html

Quando eu carrego meu código no domínio real e ligo para o serviço da Web a partir dele, é claro que funciona.

Eu já tentei mudar os cabeçalhos de controle de acesso, mas isso não ajuda.

        WebOperationContext.Current.OutgoingResponse.Headers.Add("Access-Control-Allow-Origin", "*")

        Dim MyConnection As SqlConnection = GetConnection()
        Dim cmd As New SqlCommand("SELECT provinceid,title FROM provinces WHERE CountryID=@CountryID ORDER BY title ASC", MyConnection)
        cmd.Parameters.Add(New SqlParameter("@CountryID", cid))

        Try

            While reader.Read
                values.Add(New CascadingDropDownNameValue(reader("title").ToString, reader("provinceid").ToString))
