how to connect localhost wcf service with asp.net 4.0

i have just created one wcf service for serve some functionalities to my local web project. here is my localhost wcf service web config.
<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
<compilation debug="true" targetFramework="4.5.2" />
<httpRuntime targetFramework="4.5.2"/>
</system.web>
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior name="WebHttp">
<webHttp />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="">

</binding>
</basicHttpBinding>
</bindings>
<client>

<!--

-->
<directoryBrowse enabled="true"/>
</system.webServer>
</configuration>
and finally this is my local web site web config to deal with local hosted wcf service.
<system.serviceModel>

how ever this works not fine. the following error occurs like :
The endpoint at 'http://localhost/staff_care_wcf_ws/RestServiceImpl.svc' does not have a Binding with the None MessageVersion. 'System.ServiceModel.Description.WebHttpBehavior' is only intended for use with WebHttpBinding or similar bindings."}
what going wrong here please help me out this guys.....
update

You need to delete the webHttp in the endpointBehaviors node, because the base address used in IIS for service deployment is not "http://localhost/staff_care_wcf_ws/RestServiceImpl.svc". Your WCF service has only one basicHttpsBinding endpoint. Your client configuration file should look like the following:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="LargeWeb" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
<readerQuotas maxDepth="32" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:8000/Service1.svc"
behaviorConfiguration="WebHttp" binding="basicHttpBinding" name="webHttpBinding_IService1"
contract="ConsoleApp1.IService1">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
</client>
<behaviors>
<endpointBehaviors>
<behavior name="WebHttp">
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<protocolMapping>
<add binding="basicHttpBinding" scheme="http" />
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
<standardEndpoints>
<webScriptEndpoint>
<standardEndpoint name="" crossDomainScriptAccessEnabled="true" />
</webScriptEndpoint>
</standardEndpoints>
</system.serviceModel>
</configuration>
If the WCF service is deployed to IIS, its base address should be as follows:
So your WCF configuration file has the same effect as the following configuration file:
<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
<compilation debug="true" targetFramework="4.5.2" />
<httpRuntime targetFramework="4.5.2"/>
</system.web>
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior name="WebHttp">
<webHttp />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="">
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<protocolMapping>
<add binding="basicHttpsBinding" scheme="https" />
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
<!--
To browse web app root directory during debugging, set the value below to true.
Set to false before deployment to avoid disclosing web app folder information.
-->
<directoryBrowse enabled="true"/>
</system.webServer>
</configuration>
ProtocolMapping can simplify the configuration, it will help you generate a basicHttpsBinding endpoint.
Feel free to let me know if the problem persists.
UPDATE
Your configuration file is a bit confusing, I suggest following the steps below to recreate a WCF service deployed in IIS:
Create a WCF Service Application project:
This is the project directory:
The interface of the service is stored in the IService file, and the implementation class of the service is stored in the Service1 file.
Replace the content in web.config with the following configuration information:
<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
<compilation debug="true" targetFramework="4.7.2" />
<httpRuntime targetFramework="4.7.2"/>
</system.web>
<system.serviceModel>
<services>
<service name="WcfService2.Service1"
behaviorConfiguration="CalculatorServiceBehavior">
<endpoint address=""
binding="basicHttpBinding"
contract="WcfService2.IService1"
bindingConfiguration="LargeWeb"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="CalculatorServiceBehavior">
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<basicHttpBinding>
<binding name="LargeWeb" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
<readerQuotas maxDepth="32" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
</binding>
</basicHttpBinding>
</bindings>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
<!--
To browse web app root directory during debugging, set the value below to true.
Set to false before deployment to avoid disclosing web app folder information.
-->
<directoryBrowse enabled="true"/>
</system.webServer>
</configuration>
The above configuration information will generate a basicHttpBinding endpoint.
Publish it to IIS:
Use a browser to access the service:
Use Add Service Reference to generate proxy classes to call services:
This will automatically generate the proxy class and configuration file, you can call it directly.

how can I make wcf service concurrency work?

I am new in wcf,I concurrent 10 request to test my wcf service but just response in random，3,7,1,sometimes even no response. I have search a lot and fill some code in web.config,set the currencymod,instancemode,but result still haven't any changes.I
hope someone could help check my code.
the concerned code in wcf service web.config
<system.web>

</system.net>
the service code:
[ServiceBehavior(InstanceContextMode=InstanceContextMode.PerCall,ConcurrencyMode =ConcurrencyMode.Multiple)]
public class WithDrawService : IWithDrawService
{
int IWithDrawService.TestConcurrent()
{
return 1;
}
}
this service was deployed on the windows server 2008 r2 which has 2048MB memory
I found"set ServicePointManager.DefaultConnectionLimit" could solve my problem but i don't know where should i set it. i tried to set it in my service class constructor and client but no effects.

WCF used as service reference: how do it?

I've my RESTful service hosted here .
I can use it perfectly with get&post http request.
How can I use as "service reference" in a Visual Studio project? I have added it in my test project and I see the methods correctly, but, when I try to call on of them, I get the "could not find default endpoint element that references contract in the servicemodel client" error, with http code 404.
So, I'm trying to modify my web.config file, but I get only different errors. For example, now I have try to add a SOAP endpoint,but I get a "bad request" error.
This is one of my methods (they are defined in the same way)
[OperationContract]
[WebGet(UriTemplate = "impianto.json?retista={codret}&storeID={storeID}&H={hashedString}", ResponseFormat = WebMessageFormat.Json)]
List<WrapImpianti> GetImpiantoJSON(string codret, string storeID, string hashedString);
and this is the web.config file:

You can also try yourself adding the service reference (the link is the same as above, http://37.59.146.241:8097/isOverviewExport.svc ). Why the second line of this snippet gives me the error I wrote above?
var svc = new ServiceReference5.isOverviewExportClient();
var ret = svc.GetImpiantoXML("123456", "AAA111", "test");
So, how can I use it as service reference in VS? I was thinking I have to set the soap endpoint, but maybe it isn't correct. Can you help me? :)

Ajax Enabled WCF service with Windows Authentication works on Local But not when Hosted

I have a WCF ajax enabled web service that uses Windows Authentication, when I run the application on my local PC it works perfectly, but when I host it does not want to pass through the client credentials to the service.
I keep getting this error:
Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'
I believe I have included all the necessary configuration but I am not sure.

Stacked up with web service configuration

I'm currently stacked with the web service that im creating right now. when Testing it in local it all works fine but when I try to deploy it to the web server it throws me the following error
An error occurred while trying to make a request to URI '...my web service URI here....'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details.

This sounds like the error you get when you are trying to use silverlight to access a webservice from where it is not hosted. If this is the case you need to add a clientaccesspolicy.xml to your web application folder.
MSDN article on allowing crossdomain access for a silverlight application.
