Asynchronous web service not getting kicked of.

I have a Web Service which I call ASynchronously. The problem its not
getting kicked off. This is how I am calling it over HTTP and after
calling the webservice I have a redirect to another page. I don't know
if that is allowed.

Here is how I call it on a click of a button.

COASTWebService .DeployService proxy = new
COASTWebService .DeployService( );
IAsyncResult result;
result = proxy.BeginBuil dPackage(deploy mentID,
_currentPagePar am.BranchID, null, null);
Session["IAsyncResu lt"] = result; //I really do not need this
Response.Redire ct(string.Forma t("DeployStatus .aspx?deploymen t_id={0}&branch _id={1}",deploy mentID,_current PageParam.Branc hID),true);
This is the web service code
namespace Composer.WebUI. COASTWebService {
using System.Diagnost ics;
using System.Xml.Seri alization;
using System;
using System.Web.Serv ices.Protocols;
using System.Componen tModel;
using System.Web.Serv ices;
/// <remarks/>
[System.Diagnost ics.DebuggerSte pThroughAttribu te()]
[System.Componen tModel.Designer CategoryAttribu te("code")]

[System.Web.Serv ices.WebService BindingAttribut e(Name="DeployS erviceSoap",
Namespace="http ://tempuri.org/")]
public class DeployService :
System.Web.Serv ices.Protocols. SoapHttpClientP rotocol {

/// <remarks/>
public DeployService() {
this.Url =
"http://localhost/COASTWebService/DeployService.a smx";

/// <remarks/>

[System.Web.Serv ices.Protocols. SoapDocumentMet hodAttribute("h ttp://tempuri.org/BuildPackage",
RequestNamespac e="http://tempuri.org/",
ResponseNamespa ce="http://tempuri.org/",
Use=System.Web. Services.Descri ption.SoapBindi ngUse.Literal,
ParameterStyle= System.Web.Serv ices.Protocols. SoapParameterSt yle.Wrapped)]
public void BuildPackage(in t deploymentID, int branchID) {
this.Invoke("Bu ildPackage", new object[] {

/// <remarks/>
public System.IAsyncRe sult BeginBuildPacka ge(int deploymentID,
int branchID, System.AsyncCal lback callback, object asyncState) {
return this.BeginInvok e("BuildPackage ", new object[] {
branchID}, callback, asyncState);

/// <remarks/>
public void EndBuildPackage (System.IAsyncR esult asyncResult) {
this.EndInvoke( asyncResult);
In the redirected page, on the LOAD of page this is what I do. I really
not do this as I constantly keep polling in the DB so I know the exact
state. But its just not happening.

if (Session["IAsyncResu lt"] != null)
COASTWebService .DeployService proxy = new
Composer.WebUI. COASTWebService .DeployService( );
result = (IAsyncResult)S ession["IAsyncResu lt"];
if (result.IsCompl eted)
proxy.EndBuildP ackage(result);

I am new to Async concept so please be easy...

Hi all, I've got a server that handles a relatively high number of concurrent transactions (on the magnitude of 1000's per second). Client applications establish socket connections with the server. Data is sent and received over these connections using the asynchronous model. The server is currently in beta testing. Sporadically over the course of the day, I'll observe the thread count on the process (via perfmon) start climbing....

Hi There This question is about calling an asynchronous web service from the UI thread. Unless I am making a fundamental error, it appears that the asynchronous web service call seems to spark off an Application.DoEvents() when system resources are low and the message loop has queued requests. Here are some snippets of code to describe the problem:

Hi, I've found what appears to be a bug with ASP.NET web service method invocation - making it impossible to invoke and get the result of a synchronous web call after an asynchronous call has been made if both are using sessions. Heres an example for two calls in the web service, the first is expected to be executed asynchronously by the client and the second to get the progress of the first while it is executing:

I have two different scenarios: 1. I have an application that calls a web service and passes an object. Web Service takes that object and does some stuff with it, which could take some time. It seems to me that in this case it would be appropriate to use asynchronous web service. Am I correct?

I have a large problem, and I believe there is not yet a way to solve this using IIS and ASP.NET. I hope someone has a solution which we couldn't find.

This means, that on the backend, while sampleuser logs in to our service with only one username and password, he is automatically logged in to...

I am writing a service that monitors when a particular app is started. Works, but I need to get the user who is currently logged in, and of course Environment.UserName returns the service logon (NT_AUTHORITY\SYSTEM). I understand that when the service starts, no user may be logged in, but that's ok, as the app I am monitoring can only be run by a logged in user. Do I need to use WMI to get the user context of Explorer.exe or is there a...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...
