    <p>I am trying to use third-party web service (php-based) in asp.net c# application, and failed with service configuration.Already tried add service/web reference - all the same error :</p> <blockquote> <p>The content type text/html of the response message does not match the content type of the binding (text/xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 402 bytes of the response were: '&lt;?xml version="1.0" encoding="utf-8"?>&lt;soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">&lt;soap:Body>;&lt;...</p> </blockquote> <p>[Response was edited manually to correctly display > &lt; chars, it's perfectly valid otherwise]</p> <p>To me it seems like a perfectly valid response, and I tried to look at what fiddler writes in response headers - Content-Type: text/html, which is probably the source of issue - webservice sents wrong content-type (text/html instead of text/xml) , but how to configure my client to ignore/override received content-type ? Googling gets me nothing so please, if anyone could help - where problem is? Binding\endpoint configuration is a default basicHttpBinding/endpoint which is generated by VS2010 when using Add Service Reference option, nothing was changed there. Thanks in advance.</p> <p>[app.config]</p> <pre><code>&lt;?xml version="1.0"?&gt; &lt;configuration&gt; &lt;configSections&gt; &lt;sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"&gt; &lt;section name="Collection.ServicePlayground.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/&gt; &lt;/sectionGroup&gt; &lt;/configSections&gt; &lt;system.serviceModel&gt; &lt;bindings&gt; &lt;basicHttpBinding&gt; &lt;binding name="SmsServiceSoap1" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"&gt; &lt;readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /&gt; &lt;security mode="None"&gt; transport clientCredentialType="None" proxyCredentialType="None" realm="" /&gt; &lt;message clientCredentialType="UserName" algorithmSuite="Default" /&gt; &lt;/security&gt; &lt;/binding&gt; &lt;/basicHttpBinding&gt; &lt;/bindings&gt; &lt;client&gt; &lt;endpoint address="http://ws1.streamsms.ru/SmsService.php" binding="basicHttpBinding" bindingConfiguration="SmsServiceSoap1" contract="SmsService.SmsServiceSoap" name="SmsServiceSoap2" /&gt; &lt;/client&gt; &lt;/system.serviceModel&gt; &lt;applicationSettings&gt; &lt;Collection.ServicePlayground.Properties.Settings&gt; &lt;setting name="Collection_ServicePlayground_WSStreamProvider_SmsService" serializeAs="String"&gt; &lt;value&gt;http://ws1.streamsms.ru/SmsService.php&lt;/value&gt; &lt;/setting&gt; &lt;/Collection.ServicePlayground.Properties.Settings&gt; &lt;/applicationSettings&gt; &lt;/configuration&gt; </code></pre>

    1. COAre you sure that the service is using basicHttpBinding? Can you access the wsdl? Sounds like a binding mismatch between client and service.

    2. COI can access WSDL but it gives me nothing new about binding :(. It's definitely binding problem - custom ws test tool (soapUI) works perfectly with service, and the issue is that response header from service contains ContentType:text/html which is just plain wrong - response content is perfectly valid soap/xml. I just dont get how to configure my binding/endpoint to not take that header seriously :)

    3. COBTW, may be it can shed some light, web service is php-based, and basicHttpBinding was created by vs2010-option "Add Service Reference".

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
