  1. POWhy to use beginInvoke and DebuggerStepThroughAttribute and other attributes
    text
    copied!<p>While I was going through some code sample, I noticed the following attributes which I do not understand how used.This classes seems to be generated from xsd.</p> <pre><code>[System.Diagnostics.DebuggerStepThroughAttribute()] [System.ComponentModel.DesignerCategoryAttribute("code")] [System.Web.Services.WebServiceBindingAttribute(Name="FlightHistoryGetRecordsSOAPBinding", Namespace="http://www.pathfinder-xml.com/FlightHistoryService.wsdl")] [System.Web.Services.Protocols.SoapDocumentMethodAttribute("", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Bare)] [return: System.Xml.Serialization.XmlElementAttribute("FlightHistoryGetRecordsResponse", Namespace="http://pathfinder-xml/FlightHistoryService.xsd")] </code></pre> <p>Also could not understand the following methods:</p> <pre><code>public System.IAsyncResult BeginFlightHistoryGetRecordsOperation(FlightHistoryGetRecordsRequest FlightHistoryGetRecordsRequest, System.AsyncCallback callback, object asyncState) { return this.BeginInvoke("FlightHistoryGetRecordsOperation", new object[] { FlightHistoryGetRecordsRequest}, callback, asyncState); } /// &lt;remarks/&gt; public FlightHistoryGetRecordsResponse EndFlightHistoryGetRecordsOperation(System.IAsyncResult asyncResult) { object[] results = this.EndInvoke(asyncResult); return ((FlightHistoryGetRecordsResponse)(results[0])); } </code></pre> <p>So I have the following questions:<br> 1. What does each attribute do.<br> 2.What is the return doing in attributes?<br> 3.What are the parameters used in <code>FlightHistoryGetRecordsResponse</code> method and why is it returning <code>this.BeginInvoke</code>?</p>
