I discovered an issue in VS 2008 Beta 2 that will most likely be an issue when the product goes to RTM. I notified Microsoft of the issue and they have pushed this back to VS 2008 SP1 because its so late in the development process. The issue is with adding a web service to a website. When adding a web service to a pre-existing website, a template for a web service is created. It will take VS 2008 to realize that the file has inline code. Then, when adding a snippet (right-click in the code window and choose Insert Snippet) that contains imports for a namespace, the namespaces are added at the top of the page like:
<%@ import namespace="System.Data" %>
There is currently no resolution to this issue.
