WCF / ASMX :: WCF Service Returns Blank Data?
Jul 22, 2010
I'm new to WCF and this is definitely a rookie question. Why does my browser show/return nothing when I type this URL: http://localhost/service.svc/root, using the code below. I was hoping I would see an xml respone like: <double>56.78</double>. service.svc

I have a web application in ASP.NET 4.0. I've added an asmx service, primarily as a source for the autocomplete extender's lookup values.
When I debug on my machine locally, everything works fine. However, when I deploy the web application to IIS 7.5, I get a HTTP 404 response when trying to send data to the service.
I am able to browse to the service definition, see the available operations. Tellingly, however, when I use the test pages to test the service using POST, I receive an HTTP 404 again.
I'm not sure what is going on. I did create the asmx file within my web application and it is deployed in the virtual directory of my otherwise working production application. Is there an issue with the .asmx file being deployed in the same virtual directory, perhaps?

In our project WCF service is acting as our BLL.
i had scenario where i had to fill list of object class without knowing its type see code:
Added contract
[OperationContract]
dynamic GetReferenceTableData(string tableName);
method in service:
public dynamic GetReferenceTableData(string tableName)
{
try
{
dynamic tableData = ReferenceTableDAL.GetReferenceTableData(tableName);
return tableData;
}
catch (Exception ex)
{
throw;
}
}
method at DAL(ReferenceTableDAL):
public static dynamic GetReferenceTableData(string tableName)
{
Database db = DatabaseFactory.CreateDatabase(Flags.ConnectionStringKey);
DbCommand dbCommand = db.GetStoredProcCommand("USP_GETTABLEDATA");
dynamic objDynamic = null;
if (tableName.ToLower() == "a")
{
objDynamic = new List<A>();
}
else if (tableName.ToLower() == "b")
{
objDynamic = new List<B>();
}
else if (tableName.ToLower() == "c")
{
objDynamic = new List<C>();
}
try
{
db.DiscoverParameters(dbCommand);
dbCommand.Parameters["IN_TABLENAME"].Value = tableName;
DataSet dsTableData = db.ExecuteDataSet(dbCommand);
if (tableName.ToLower() == "a")
{
foreach (DataRow dataRow in dsTableData.Tables[0].Rows)
{
objDynamic.Add((A)dataRow);
}
}
else if (tableName.ToLower() == "b")
{
foreach (DataRow dataRow in dsTableData.Tables[0].Rows)
{
objDynamic.Add((B)dataRow);
}
}
else if (tableName.ToLower() == "c")
{
foreach (DataRow dataRow in dsTableData.Tables[0].Rows)
{
objDynamic.Add((C)dataRow);
}
}
}
catch (Exception ex)
{
throw;
}
return objDynamic;
}
@ Aspx
try
{
using (DataServiceRef.DataServiceClient petService = new DataServiceRef.DataServiceClient())
{
dynamic tableData = petService.GetReferenceTableData(tableName);
//tableData is null ,exception
}
}
catch (Exception ex)
{
throw;
}
There is no exception at dal or service end when i debug list gets filled ok but when returns to aspx error at aspx(no exception gets caught at @ service) but exception at aspx i.e:
Message:The underlying connection was closed: The connection was closed unexpectedly.
Stack Trace: at System.Net.HttpWebRequest.GetResponse()

I am new to web service. I am trying to connection to an oracle database with 2 input parameters. The web service works fine in the VS2010 environment but when i publish it on to my local machine IIS or on the test web server I do not get a result set back. I get this:
<?xml version="1.0" encoding="utf-8" ?>
<DataSet xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xsi:nil="true" xmlns="http://test.INT/" />

I am trying to figure out why this service does not return any data. The service does not error out is just doesn't return any data. When I take the Linq into LinqPad the query returns exactly as I expect. So I am wondering if the problem is getting my return data into a List<string>??
[Code]....
I don't know what else to say to help. When I set a break point on the "return LoanStats" line a quick watch shows an empty results view.

I am using a script manager for ASP.NET MVC to combine and compact CSS files and JavaScript files for pages on a website. For the most part this works as expected, however there are times (couple of times per week) when the HTTP handler responsible for returning the content returns an empty response and so pages load without any CSS - the HTML returns and the images load as well. When this happens, refreshing the page does not resolve the problem, while resetting IIS always resolves the problem. Also, without resetting IIS, after some time the problem stops.
Normally the script handler logs errors, however there are no errors logged during the issue. It seems as if the handler is never invoked. There are no failed request logs generated by IIS.
I monitored resource usage when this was happening and did not notice anything out of the ordinary. The web server is running IIS 7 and has low CPU usage. I increased some parameters in IIS settings regarding the number of allowable requests to process, the problem still exists though perhaps less frequent. The website receives about 1.5 million pageviews monthly.

I have built a WCF Service that is being consumed by a Silverlight app. At first I created one method that was very simple:
public String SfTest()
{
return "SF Test";
}
No poblem. My silverlight app references my service and displays "SF Test" in a textbox. Now I add a method to my wcf service like this:
public List<String> GetTest()
{
List<String> list = new List<string>();
String a = "a";
list.Add(a);
String b = "b";
list.Add(b);
return list;
}
I update the reference to the service in my Silverlight app and the using statement in my xaml cs page throws an error like the service doesn't even exist although it is there. I am assuming the problem has to do with datatypes or serialization or something like that but it is driving me up the wall. Why can't I consume a simple generic list in my Silverlight app through the WCF service.

Ok, I almost hate to ask this because I'm sure it's been covered many times on this forum, but I'm starting to get too frustrated trying to get it to work, so I'm gonna ask anyway.I have setup forms authentication on my site and have it working without any issues. What I'm trying to do now is to add "Remember Me" functionality so that the users don't have to log in each time they access the site. I'm able to get the authentication part down, but the issue I'm having is that when the user logs in, I set certain attributes in Session variables for that user (name, site role, etc.). These values are obtained from a database after the user has been authenticated, based on the username. What I'm having problems with is getting at this username from the FormsAuthentication cookie.
After I authenticate the first time, I setup my cookie this way:
[Code]....
I have tried getting at the Username utilizing the User prinicipal, but it just returns blank.

I have a webapplication based on MonoRail, where we utilize the routing feature from MonoRail. On the first request after the application has started, the routing isn't initialized. To circumvent this, I have the following code in Application_OnError():
public virtual void Application_OnError()
{
if ( // identified as routing error )
Server.TransferRequest( Context.Request.RawUrl, false );
return;
}
Problem beeing that on our development server (which runs server 2008 R2, with IIS 7.5 and .NET 3.5) returns a blank page without headers, but on my workstation (which runs win7, IIS 7.5 and .NET 3.5) it works fine.
What could be the cause of this? If the code in Application_OnError() throws an exception, what would be the expected output?
I have verified the following:
The access-log shows one entry, I'm not sure if a TransferRequest would show up as a second entry when invoked successfullyThe application actually do some work according to my internal logs, and it doesn't die since a subsequent requests works flawlessly (because routing will be active)

I´m new to web services and currently working with an integration to a third party system. I have created a web service that creates and exports a <List> of objects. The challange I have is that the third party company consuming my created web service wants to have the data as a XML document just as it is presented when I push the "Invoke button" when testing my web service on the server it resides on. Doing so I get all my exported data presented as a nice XML document. Since a web service actually exports this XML it should be a fairly simple task, but I do not know how? Would perhaps anyone have a code snippet consuming a web service and present the data just as an XML document? Or could point me to an example? I´m using VS 2008.

A customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.

I am working with a .net 2.0 asmx webservice (code below)I need to return 4 "items", which will be based on the success of failure of the webservice, and the actual XML imput itself.The Webservice needs to be asyncronous.I have included the code below, but am happy for someone to re-do it as it's been built up on tutorials and examples.At present, I don't believe the async is working, and the returns don't seem to be getting done.I have also built a test harness, and testing, which allows me to send some custom XML and then receive the response.

Is it possible to run a web service as a particular user/service account in the same way a Windows service can?I have a service account used for connecting to the DB and want to run the webservice under this account as the users using the webservice won't have DB access.The way I see to do it is to include the Impersonate option in the Web.config file, but is there any better way to do this?

My WCF Client calls my WCF Service which then calls ASMX Web Service. The problem is i have configured my wcf client and wcf service to windows credentials type but when wcf service calls asmx service the user credentials (default windowsidentity) is not passed to asmx service.
In WCF Service i am able to get user identity by using : Thread.CurrentPrincipal.Identity.Name;
WCF Service - i have disabled anonymous access and enabled windows authentication. ASMX Web Service - i have disabled anonymous access and enabled windows authentication.
