ERROR: does not contain a definition for 'SetPolicy' error

[kalasp]

Hi im using WSE3.0 with C#.
I know that WSE is old but I still have to use it. I get this error: Error 11 'WeldPointClient.localhost.Service' does not contain a definition for 'SetPolicy' E:\WeldPointClient\WeldPointClient\Form1.cs 35 18 WeldPointClient. When im trying to use Policies.

}

private void button1_Click(object sender, EventArgs e)
{

WeldSupportService.Service1 weldPointClientService = new Service1();
weldPointClientService.SetPolicy("ClientPolicy");

try
{

textBox1.Text = s;
}

[WebMethod]

return "000";

I have read about this problem on the forum and I have followed the advices but I don´t seem to get it to work. Either there is something I don´t understand or something I missed. I have spent several hours on this. Help would be greatly appreciated.
