using System.CodeDom.Compiler;
using System.Security.Permissions;
using System.Web.Services;
using System.Web.Services.Description;
using System.Web.Services.Discovery;
using System.Xml;
using System.Xml.Serialization;

Remarks

A WebReference object is used to pass information about a set of Web services to the static GenerateWebReferences method of the ServiceDescriptionImporter class.

Constructors

WebReference(DiscoveryClientDocumentCollection, CodeNamespace)	Initializes a new instance of the WebReference class with the given description document collection and proxy code namespace.
