The type or namespace name 'dutyfree' could not be found (are you missing a using directive or an assembly reference?)

I am working on One Project which is consuming One Webservice "dutyfree". I add the Webreference and it is working very fine on my Local Machine.But as I publish it on my Server it is giving error
"The type or namespace name 'dutyfree' could not be found (are you missing a using directive or an assembly reference?)"

I have check that the webrefernce is converted into App_WebReferences.dll in the bin directory on server.
Same code was working very fine on Localhost.

protected void Page_Load(object sender, EventArgs e)
{
dutyfree.Services test = new dutyfree.Services();
DataTable dt = test.GetProductCatalog2();
Repeater1.DataSource = dt;
Repeater1.DataBind();
}

Kindly help me.I am stuck to it.I have done lots of google.Every thing seems to be fine but still getting it.
