An error occurred while receiving the HTTP response WCF

I have a Windows app connecting to a WCF service that uses Entity Framework and is hosted in IIS. I get this error message when I try to return result of method in WCF service to my windows app:
An error occurred while receiving the HTTP response to http://localhost/BuyAndRechargeWcfService/BuyAndRechargeService.svc. > This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.
Here is my web.config file of the WCF service:

When I try to debug the code I reach the return value of HandleCustomer method in WCF service and then I can't complete debugging (can't move to other statement the arrows is been disabled).
Please tell me if you want to provide you in any other parts of code

If possible, please check whether there is a record of 0 in the data found in the database.
When read in a program, it is converted to the corresponding enumeration type (enum), which does not define the enumeration value corresponding to 0. In this case, the conversion to an enumeration type does not throw an exception, and the value of the property remains 0 after the conversion. But when it is returned to the WCF client, the above exception is thrown.
The solution is to define the enumerated value corresponding to 0 in the enumerated type.

How to Solve DTD is prohibited in this xml document in WCF while connecting with Xamarin forms

I'm trying to connect my WCF service in Xamarine Forms, but in runtime I am getting this error
For security reasons DTD is prohibited in this XML document. To enable DTD processing set the DtdProcessing property on XmlReaderSettings to Parse and pass the settings into XmlReader.Create method.

Can anyone please tell me where I have to do changes to resolve this error?

This error has nothing to do with the wcf service. As the message says, set the DtdProcessing property on XmlReaderSettings to Parse and pass the settings to the XmlReader.Create method. You can refer to the code below.
https://learn.microsoft.com/en-us/dotnet/api/system.xml.xmlreadersettings.dtdprocessing?view=net-6.0
using System;
using System.Xml;
using System.Xml.Schema;
using System.IO;
public class Sample {
public static void Main() {
// Set the validation settings.
XmlReaderSettings settings = new XmlReaderSettings();
settings.DtdProcessing = DtdProcessing.Parse;
settings.ValidationType = ValidationType.DTD;
settings.ValidationEventHandler += new ValidationEventHandler (ValidationCallBack);
// Create the XmlReader object.
XmlReader reader = XmlReader.Create("itemDTD.xml", settings);
// Parse the file.
while (reader.Read());
}
// Display any validation errors.
private static void ValidationCallBack(object sender, ValidationEventArgs e) {
Console.WriteLine("Validation Error: {0}", e.Message);
}
}

Return JSON instead of XML web service

I'm wanting my web service to return JSON not XML, currently it's returning JSON wrapped in XML. View the source of my URL http://soulappvm.cloudapp.net/SAService/Service.svc/userlist produces the following...
<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">[{"Name":"Daniel1user","Password":"40d5e24c5c906103a980ec7c69c100c5","Address":"123 st"},{"Name":"Daniel2user","Password":"90a1587cbe37d4a2a128ce758f338587","Address":"1234 st"},{"Name":"Daniel3user","Password":"f97c27c65d3af0d18657cbae16f9d57e","Address":"ccc"},{"Name":"user1user","Password":"def907bec025cd03bf738c3612bd7926","Address":"ds"},{"Name":"user2user","Password":"0fa04e1c4a5720195b106df9e746a72b","Address":"ff"}]</string>
Is there simple way to get it to just return JSON? I have tried ResponseFormat = WebMessageFormat.Json but that did not work.

How to set webservice endpoint address at runtime?

I want to connect to a webservice url which is provided at runtime when user logs in. so i need to set Endpoint.Address in app.config at runtime.
EndpointIdentity spn = EndpointIdentity.CreateSpnIdentity("host/mikev-ws");
Uri uri = new Uri(txtURL.text.trim());
var address = new EndpointAddress(uri, spn);
var client = new EchoServiceClient("WSHttpBinding_IEchoService", address);
client.Close();
I placed this code on button click ,and gets the value of uri from textbox. Code is executing correctly and then getting an error message
"Address property on channelfactory.endpoint was null"
my app.config is:
<configuration>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="LoginServiceSoap" />
</basicHttpBinding>
</bindings>
<client>
<!--<endpoint address="http://localhost:3073/LoginService.asmx" binding="basicHttpBinding"-->
<endpoint address="" binding="basicHttpBinding"
bindingConfiguration="LoginServiceSoap" contract="LoginService.LoginServiceSoap"
name="LoginServiceSoap" />
</client>
</system.serviceModel>
</configuration>

I've done something similar in a recent project, where I only wanted to set the endpoint and authentication programatically and not use the config file at all:
public static class ServiceClientFactory
{
public static HttpBindingBase BuildNavisionBinding(string endpointUrl)
{
//http://blog.randomdust.com/index.php/2010/10/could-not-establish-trust-relationship-for-the-ssl-tls-secure-channel/
//http://www.codeproject.com/Forums/1649/Csharp.aspx?fid=1649&df=90&mpp=25&sort=Position&select=3126652&tid=3121885
ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(delegate
{
return true;
});
if (endpointUrl.ToLower().StartsWith("https"))
{
var binding = new BasicHttpsBinding(BasicHttpsSecurityMode.Transport);
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;
binding.MaxReceivedMessageSize = int.MaxValue - 1;
return binding;
}
else
{
var binding = new BasicHttpBinding(BasicHttpSecurityMode.TransportCredentialOnly);
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;
binding.MaxReceivedMessageSize = int.MaxValue - 1;
return binding;
}
}
public static TClient CreateClient<TClient, TChannel>(string endpoint, string username, string password)
where TClient : ClientBase<TChannel>
where TChannel : class
{
var client = (TClient)
Activator.CreateInstance(
typeof (TClient),
BuildNavisionBinding(endpoint),
new EndpointAddress(endpoint));
if (null == client.ClientCredentials)
throw new Exception(
string.Format("Error initializing [{0}] client. Client Credentials object was null",
typeof(TClient).Name));
client.ClientCredentials.Windows.ClientCredential =
new NetworkCredential(
username,
password);
client.ClientCredentials.Windows.AllowedImpersonationLevel =
TokenImpersonationLevel.Delegation;
client.Endpoint.Binding.SendTimeout = new TimeSpan(0, 0, 4, 0);
client.Endpoint.Binding.ReceiveTimeout = new TimeSpan(0, 4, 0);
client.Endpoint.Binding.OpenTimeout = new TimeSpan(0, 0, 4, 0);
return client;
}
So from your example:
var client = ServiceClientFactory.CreateClient<EchoServiceClient, IEchoServicePort(txtUrl.text.trim(), /* authentication */);

Trying to read web.config file for an IIS site from a Windows service

I am trying to look for a special web.config file for a web site installed on a local IIS. I do this search from a Windows service. I do the following:
using (ServerManager serverManager = new ServerManager())
{
for (int r = 0; r < serverManager.Sites.Count; r++)
{
string strSiteName = serverManager.Sites[r].Name;
ApplicationCollection arrApps = serverManager.Sites[r].Applications;
for (int a = 0; a < arrApps.Count; a++)
{
Microsoft.Web.Administration.Application aa = arrApps[a];
foreach (VirtualDirectory vd2 in aa.VirtualDirectories)
{
string strPhysPath = Environment.ExpandEnvironmentVariables(vd2.PhysicalPath);
int rr = 0;
try
{
Configuration cnfg = serverManager.GetWebConfiguration(strSiteName, strPhysPath);
if (cnfg != null)
{
string swww = getWebConfigGeneralParamValue(cnfg, "SpecNodeName");
}
}
catch
{
//Error
}
}
}
}
Where,
public static string getWebConfigGeneralParamValue(Configuration config, string strParamKey)
{
string strRes = null;
try
{
ConfigurationSection configSection1 = config.GetSection("configuration");
if (configSection1 != null)
{
ConfigurationElement configGeneralParams = configSection1.GetChildElement("GeneralParams");
if (configGeneralParams != null)
{
ConfigurationElementCollection configCol = configSection1.GetCollection();
if (configCol != null)
{
strRes = configCol[strParamKey].ToString();
}
}
}
}
catch(Exception ex)
{
strRes = null;
}
return strRes;
}
and the web.config file that should be recognized by this script is something like this:
<?xml version="1.0"?>
<!--
For more information on how to configure your ASP.NET application, please visit
http://go.microsoft.com/fwlink/?LinkId=169433
-->
<configuration>
<!-- regular ASP.NET config stuff -->
<GeneralParams>
<param key="SpecNodeName" value="Special Node Value"/>
</GeneralParams>
</configuration>
But what I get is that config.GetSection("configuration"); throws this exception:
{"Filename:
\\?\C:\inetpub\wwwroot\C:\Users\Dev\Desktop\CSharp\MyTestWebApp\MyTestWebApp\web.config\r\nError:
The configuration section 'configuration' cannot be read because it is
missing a section declaration\r\n\r\n"}
Any idea how to make it work?

You need not to target configuration, you need to target that particular node from where you need to get your data. here is the example.
using(ServerManager mgr = ServerManager.OpenRemote("Some-Server")) {
Configuration config = mgr.GetWebConfiguration("site-name", "/test-application");
ConfigurationSection appSettingsSection = config.GetSection("appSettings");
ConfigurationElementCollection appSettingsCollection = appSettingsSection.GetCollection();
ConfigurationElement addElement = appSettingsCollection.CreateElement("add");
addElement["key"] = #"NewSetting1";
addElement["value"] = #"SomeValue";
appSettingsCollection.Add(addElement);
serverManager.CommitChanges();
}

I am feeling, if you have web.config why you want to use ServerManager.
Take a look at below code, this I have been using in my code and it works as a charm.
What it does is it loads web.config in readable format.
var assemblyPath = Path.GetDirectoryName(typeof (ConfigurationTests).Assembly.Location);
string webConfigPath = MyPath;
string directory = System.IO.Path.GetFullPath(Path.Combine(assemblyPath,webConfigPath));
Console.WriteLine(directory);
Assert.That(Directory.Exists(directory));
VirtualDirectoryMapping vdm = new VirtualDirectoryMapping(directory, true);
WebConfigurationFileMap wcfm = new WebConfigurationFileMap();
wcfm.VirtualDirectories.Add("/", vdm);
System.Configuration.Configuration webConfig = WebConfigurationManager.OpenMappedWebConfiguration(wcfm, "/");
var connectionString = webConfig.ConnectionStrings.ConnectionStrings["ConnectionString"].ConnectionString;
Console.WriteLine("Connection String:");
Console.WriteLine(connectionString);
Console.WriteLine("AppSettings:");
foreach (var key in webConfig.AppSettings.Settings.AllKeys)
{
Console.WriteLine("{0} : {1}", key, webConfig.AppSettings.Settings[key].Value);
}
