I am writting a winforms c# 2.0 application that needs to put an XML file into a document library on SharePoint.
I want to use a WebService instead of using the ob
I'm not sure if it will solve your problem but, when you reference the webservice, don't use the [site] part of the URL.
Try instead: http://[server]/_vti_bin/[webservice].
I'm not an expert in SP but I'm pretty sure the webservices belongs to the main server, not to an especific site.
Hope it helps.
