For questions regarding any kind of WebForms project, such as ASP .Net Websites and WebServices, please use http://forums.asp.net/

These forums (forums.microsoft.com/msdn)are for Windows Forms (desktop) applications and services.

Development for the web is a very broad topic and differs in many ways from development for the desktop. Because of this, Microsoft has a dedicated community for web development. The asp.net website contains information about all aspects of web development, including not only Visual Studio related content, but also IIS, SQL, and many other supporting technologies.

Here is a direct link to the VB language specific section of the site: http://forums.asp.net/36.aspx

Please join the asp.net community for the best response to .Net web development related questions.

-Edit Note-

There is a forum here at MSDN for Web Services and XML Serialization because these topics are purely about code and do not involve WebForms. If your question is specificaly about Web Service code or XML Serialization, you may post it at http://forums.microsoft.com/MSDN/ShowForum.aspx?ForumID=46&SiteID=1. However, you are still encouraged to use the asp.net website as there are more active web gurus there.
