I have a WCF Client (console app) that calls a WCF web service and I'm trying to get the raw XML response from within my Console Application.
Does anyone have an idea or code snippet on how to do this?
You could use a client Message Inspector
Check out this link
In your BeforeSendRequest you can simply call ToString() on the message.
I was able to get the raw xml using this method:
string _serial = SerializeObj(retVal);
public string SerializeObj<T>(T obj)
{
XmlSerializer xmlSerializer = new XmlSerializer(obj.GetType());
using (StringWriter txtWriter= new StringWriter())
{
xmlSerializer.Serialize(txtWriter, obj);
return txtWriter.ToString();
}
}

I'm new to BizTalk and WCF services and am trying to figure out how to use a WCF service to deliver XML data to Biztalk. I think I'm close but when I call the WCF service operation, the operation executes successfully but does not appear to generate any kind of a message in Biztalk. Am I wrong in assuming that simply calling an operation is enough to trigger a message to BizTalk?
Below is my code and some details about my BizTalk configuration:
WCF service:
public interface IService1
{
[OperationContract, XmlSerializerFormat]
XmlDocument GetXMLDocument(string sourceXML);
}
public class Service1 : IService1
{
public XmlDocument GetXMLDocument(string sourceXML)
{
XmlDocument doc = new XmlDocument();
doc.LoadXml(sourceXML);
return doc;
}
}
Calling application (button click calls the service):
protected void Button2_Click(object sender, EventArgs e)
{
XmlDocument doc = new XmlDocument();
doc.AppendChild(doc.CreateNode(XmlNodeType.Element, "Patients", "test"));
SendDoc(doc);
}
protected void SendDoc(XmlDocument doc)
{
//use a Service Client Object to call the service
objServiceClientobjService.GetXMLDocument(doc.OuterXml);
}
BizTalk configuration:
Receive Port:
Port type: One-Way
Receive Location:
Type: WCF-Custom with basicHTTP binding
Endpoint Address is the same as the IIS hosted WCF Service
Receive Pipeline Type: XMLReceive
Your implementation is not correct. There is no link between your WCF service and BizTalk. If you want to receive xml in BizTalk then you need to expose either an Orchestration or Xml Schema as WCF service using BizTalk WCF Web Service Publishing Wizard. This gets installed with BizTalk. Please see link for more details: msdn link
The solution I always use, is to expose an endpoint. Take a look at this example:
I have create a Rest based WCF service and it used in a java mobile app is there a way to post values from the java mobile app to my service and i can use it in my application
Yes, try setting the method for your function to POST:
[WebInvoke(UriTemplate = "MyFunction", Method = "POST")]
public string MyFunction()
{
//implementation
}
My application is accessing a WCF service hosted at the server.
When i try to call a Method with [WebInvoke] attribute the response returned is always "error".
All other methods with [WebGet] attribute are working fine.
The interface as in the reference.cs is
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")]
[System.ServiceModel.ServiceContractAttribute(ConfigurationName="SyncService.IService")]
public interface IService
{
[WebInvoke(BodyStyle = WebMessageBodyStyle.WrappedRequest)]
[System.ServiceModel.OperationContractAttribute(Action="", ReplyAction="")]
[System.ServiceModel.FaultContractAttribute(typeof(DataSynchronization.SyncService.WebExceptionDetail), Action="Update", Name="WebExceptionDetail", Namespace="http://schemas.datacontract.org/xxx.WebServices")]
string Update(string mode, string data);
}
whenever i try to call the Update method of the service using the code
string response = objClient.Update("manual", string data);
the response obtained is "Error".and the log displays
Error -
"System.Xml.Schema.XmlSchemaValidationException:
The element 'providers' cannot contain
text. List of possible elements
expected: 'provider'". on calling
Update
The service is hosted in a remote server which i cannot debug either.
I started developing an application in Silverlight that was dealing with downloading the HTML of a website and then parsing it. With Silverlight 4 this can be achieved easily by simply requesting elevated permissions. With Silverlight 3, however, the only way to get the HTML of a website is via a WebService call. My initial idea was to do the following:
public class Service1
{
[OperationContract]
public void GetHtml()
{
Uri targetUri = new Uri("http://www.google.com", UriKind.RelativeOrAbsolute);
WebClient webClient = new WebClient();
webClient.DownloadStringCompleted += this.WebClient_DownloadStringCompleted;
webClient.DownloadStringAsync(targetUri);
}
private void WebClient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
}
}
However, I realized that as soon as I make the call, which is async as well, from my Silverlight application, there is no way for me to retrieve the HTML of the website. That is why I changed to the following:
public class Service1
{
[OperationContract]
public string GetHtml()
{
Uri targetUri = new Uri("http://www.google.com", UriKind.RelativeOrAbsolute);
WebClient webClient = new WebClient();
return webClient.DownloadString(targetUri);
}
}
I believe the last approach is not that fine since it will freeze the thread. So, my question, is there a way to achieve the first approach a.k.a. make async call from an async call :). Any help would be greatly appreciated.

You can achieve your goal by implementig a Duplex Service. There is some useful information about it on the msdn site and a wonderful podcast entry by Mike Taulty. In general, you would have to modify your operation contract by splitting it into two parts. First part would initiate your WebClient download on the server. Then, on the server, after the html has been downloaded, the server would call back a contract that is implemented on the client side with the payload consisting of the required html content.
Looking for alternatives to the WCF REST start kit, ideally OSS frameworks.
Anyone got a list?

OpenRASTA is the most mature
ASP.NET MVC is a good alternative when it comes to generating REST XML and JSON feeds.
To build a rest architecture in .net you can use GenericHandlers. You can create a GenericHandler that will receive a HTTP message (POST, GET or..) and return a message of the content-type you specify.
For example I create a generic handler on the url:
http://site/getpeople.ashx?gender=female
And call it with the parmeter gender=female, as above the handler will return the following
<people>
<person>...</person>
...
<people>
And the content type would be text/xml.
This is the simplest way to implement REST web services in .NET
I also provide ServiceStack, a modern, code-first, DTO-driven, WCF replacement web services framework encouraging code and remote best-practices for creating DRY, high-perfomance, scalable REST web services.
There's no XML config, or code-gen and your one clean C# web service is enabled on all JSON, XML, SOAP, JSV, CSV, HTML endpoints out-of-the-box, automatically. It includes generic sync/async service clients providing a fast, typed, client/server communication gateway end-to-end.
It also includes generic sync/async service clients providing a fast, typed, client/server communication gateway end-to-end.
This is the complete example of all the code needed to create a simple web service, that is automatically without any config, registered and made available on all the web data formats on pre-defined and custom REST-ful routes:
public class Hello {
public string Name { get; set; }
}
public class HelloResponse {
public string Result { get; set; }
}
public class HelloService : IService<Hello> {
public object Execute(Hello request) {
return new HelloResponse { Result = "Hello, " + request.Name };
}
}
Above service can be called (without any build-steps/code-gen) in C# with the line below:
var response = client.Send<HelloResponse>(new Hello { Name = "World!" });
Console.WriteLine(response.Result); // => Hello, World
And in jQuery with:
$.getJSON('hello/World!', function(r){
alert(r.Result);
});
