Using WSE in SharePoint Context

I am currently working on integrating some existing ASP.NET forms into the /_layouts/ folder in SharePoint as they will need to run in SharePoint context. These forms call web services using Microsoft’s Web Services Enhancements add-on. The add-on creates a config file with the WSE settings for your project, but it needs to be stored in the root of the web application, so you need to make sure to put a copy of this config file in the web root of the SharePoint site (e.g. c:\Inetpub\wwwroot\wss\VirtualDirectories\<site>).
