private bool CheckAccess()

if (HttpContext.Current.Handler != null) // <--Break Point
{
string authHeader = HttpContext.Current.Request.Headers["Authorization"];
...
}
return false;
}
}
}
and in the client I wrote this code:
Service1client client = new Service1client();
client.ClientCredentials.UserName.UserName = "mmmm"
client.ClientCredentials.UserName.Password = "nnnn";
var tmp = client.DoWork(1);
the problem is after running the project, Service returns the correct result but HttpModule code didn't execute.
When I use a breakpoint in HttpModule it hits during Application_Start event. But after that it doesn't hit any more and its code doesn't execute.
Where is the problem?
Thanks
As I understand it, you defined just what to do at application start; if you want to check incoming requests, try to add these methods to your HttpModule and set breakpoints to check whether those methods are hit:
private void Application_BeginRequest(Object source,
EventArgs e)
{
CheckAccess();
}
private void Application_EndRequest(Object source, EventArgs e)
{
CheckAccess();
}
Of course you need to register those methods at application start:
application.BeginRequest +=
(new EventHandler(this.Application_BeginRequest));
application.EndRequest +=
(new EventHandler(this.Application_EndRequest));

I have WCF service with DataContract json serialization. I would like to add service endpoints to consume Protobuf data messages.
I tried to use nugget package ProtoBuf.Services.WCF.
Added endpoint via web.config configuration. However, every request on protobuf endpoint with address "proto" returns 400 Bad request. Web.config sample is written bellow. Endpoint with default address "" works properly.
Get method:
HTTP 200 OK http://localhost:65460/BeaconService.svc/GetData
HTTP 400 BAD REQUEST: http://localhost:65460/BeaconService.svc/proto/GetData

Please, which part of configuration is defective. Eventualy, what is proper way to call Get method on "proto" WCF endpoint to avoid HTTP 400 Bad request message?
Unfortunately, I have failed to implement ProtoBuf.Services.WCF and decided to use another approach. In general, WCF by default uses DataContractSerializer.
After reading this article, I realized It is possible to replace this serializer with another one, f.e. protobuf serializer in this library. So I created behavior extension, which replaces DataContractSerializer with my custom ProtobufSerializer. In configuration added another endpoint, which has set behavior extension to use my custom ProtobufSerializer.
WebHttpBehavior:
public class ProtobufBehavior : WebHttpBehavior
{
protected override IDispatchMessageFormatter GetRequestDispatchFormatter(OperationDescription operationDescription, ServiceEndpoint endpoint)
{
return new ProtobufDispatchFormatter(operationDescription);
}
protected override IDispatchMessageFormatter GetReplyDispatchFormatter(OperationDescription operationDescription, ServiceEndpoint endpoint)
{
return new ProtobufDispatchFormatter(operationDescription);
}
}
Dispatch formatter:
namespace Services.Extension.ProtobufSerializationExtension
{
public class ProtobufDispatchFormatter : IDispatchMessageFormatter
{
OperationDescription operation;
bool isVoidInput;
bool isVoidOutput;
public ProtobufDispatchFormatter(OperationDescription operation)
{
this.operation = operation;
this.isVoidInput = operation.Messages[0].Body.Parts.Count == 0;
this.isVoidOutput = operation.Messages.Count == 1 || operation.Messages[1].Body.ReturnValue.Type == typeof(void);
}
public void DeserializeRequest(Message message, object[] parameters)
{
if (!message.IsEmpty)
{
XmlDictionaryReader bodyReader = message.GetReaderAtBodyContents();
bodyReader.ReadStartElement("Binary");
byte[] rawBody = bodyReader.ReadContentAsBase64();
MemoryStream ms = new MemoryStream(rawBody);
using (StreamReader sr = new StreamReader(ms))
for (int i = 0; i < parameters.Length; i++)
parameters[i] = Serializer.Deserialize(operation.Messages[i].Body.Parts[i].Type, sr.BaseStream);
}
}
public Message SerializeReply(MessageVersion messageVersion, object[] parameters, object result)
{
byte[] body;
using (MemoryStream ms = new MemoryStream())
using (StreamWriter sw = new StreamWriter(ms))
{
Serializer.Serialize(sw.BaseStream, result);
sw.Flush();
body = ms.ToArray();
}
Message replyMessage = Message.CreateMessage(messageVersion, operation.Messages[1].Action, new RawBodyWriter(body));
replyMessage.Properties.Add(WebBodyFormatMessageProperty.Name, new WebBodyFormatMessageProperty(WebContentFormat.Raw));
return replyMessage;
}
class RawBodyWriter : BodyWriter
{
internal static readonly byte[] EmptyByteArray = new byte[0];
byte[] content;
public RawBodyWriter(byte[] content)
: base(true)
{
this.content = content;
}
protected override void OnWriteBodyContents(XmlDictionaryWriter writer)
{
writer.WriteStartElement("Binary");
writer.WriteBase64(content, 0, content.Length);
writer.WriteEndElement();
}
}
}
}
Extension element:
namespace Services.Extension.ProtobufSerializationExtension
{
public class ProtobufSerializationServiceElement : BehaviorExtensionElement
{
public override Type BehaviorType
{
get { return typeof(ProtobufBehavior); }
}
protected override object CreateBehavior()
{
return new ProtobufBehavior();
}
}
}
Web config:
<system.serviceModel>
<bindings>
<webHttpBinding>
<binding transferMode="Streamed">
<security mode="None" />
</binding>
</webHttpBinding>
</bindings>
<extensions>

Services.Extension.ProtobufSerializationExtension is name of my custom namespace inside application structure. Hope this helps someone.
I am getting an error when the client reference is used a second time for calling the underlying method. On first call, It works perfectly. I have googled it and did so many tries like setting timeouts but nothing worked. Any suggestions will be highly appreciated. Also, if more details are required please let me know, I will post the required code.
A MDI Child form will call this method.
Debugger shows CommunicationException.
Trace Viewer shows message: The operation cannot be completed because the pipe was closed. This may have been caused by the application on the other end of the pipe exiting.

I have Googled around and found all kinds of solutions to similar issues, but I can't seem to find something that works in my case.
I have a WebService that intents to upload a file to a server but i keep getting the error in the title when i want to run it from my VS2010.
I have searched over this site and the solutions have not helped me, unless i'm doing something wrong.
this is the site that i get the example: Example
here is my Interface
namespace FUWcf
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
public class FileUploadService : IFileUploadService
{
public bool UploadFileData(FileData fileData)
{
bool result = false;
try
{
//Set the location where you want to save your file
string FilePath = Path.Combine(ConfigurationManager.AppSettings["Path"], fileData.FileName);
//If fileposition sent as 0 then create an empty file
if (fileData.FilePosition == 0)
{
File.Create(FilePath).Close();
}
//Open the created file to write the buffer data starting at the given file position
using (FileStream fileStream = new FileStream(FilePath, FileMode.Open, FileAccess.ReadWrite, FileShare.Read))
{
fileStream.Seek(fileData.FilePosition, SeekOrigin.Begin);
fileStream.Write(fileData.BufferData, 0, fileData.BufferData.Length);
}
}
catch (Exception ex)
{
ErrorDetails ed = new ErrorDetails();
ed.ErrorCode = 1001;
ed.ErrorMessage = ex.Message;
throw new FaultException<ErrorDetails>(ed);
}
return result;
}
}
}
Here is the service:
namespace FUWcf
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
[ServiceContract]
public interface IFileUploadService
{
[OperationContract]
[FaultContract(typeof(ErrorDetails))]
bool UploadFileData(FileData fileData);
}

}

I hope someone can help me with this, or a link for a better example.
Thanks in advance.
You configuration is wrong ( Service name is name="FUWcd.FileUploadService" where it should be name="FUWcf.FileUploadService")
Anyway- Created the web site and added the web service like this ( You dont need Mex endpoint in web configuration as it is already on, The url will become the servicename http://{localServerName}:{port}/FileUploadService.svc):
public class FileUploadService : IFileUploadService
{
public bool UploadFileData(FileData fileData)
{
bool result = false;
try
{
//Set the location where you want to save your file
string FilePath = Path.Combine(ConfigurationManager.AppSettings["Path"], fileData.FileName);
//If fileposition sent as 0 then create an empty file
if (fileData.FilePosition == 0)
{
File.Create(FilePath).Close();
}
//Open the created file to write the buffer data starting at the given file position
using (FileStream fileStream = new FileStream(FilePath, FileMode.Open, FileAccess.ReadWrite, FileShare.Read))
{
fileStream.Seek(fileData.FilePosition, SeekOrigin.Begin);
fileStream.Write(fileData.BufferData, 0, fileData.BufferData.Length);
}
}
catch (Exception ex)
{
ErrorDetails ed = new ErrorDetails();
ed.ErrorCode = 1001;
ed.ErrorMessage = ex.Message;
throw new FaultException<ErrorDetails>(ed);
}
return result;
}
}
Data Contracts were same as well.
Then in Web.Config file added like this and it works fine:
<system.serviceModel>
<services>
<service name="WebApplication1.FileUploadService">
<endpoint address="fileService" binding="wsHttpBinding" bindingConfiguration=""
contract="WebApplication1.IFileUploadService" />

Here i am implementing custom usernamepasswordvalidator in WCF RESTfull service.What i need is while invoking this one http://localhost:12229/RestServiceImpl.svc/GetStudentObj through Chrome REST Client it is not validating the username password..it directly invoke this method and fetching the result.What am i doing wrong here??
My interface
[ServiceContract]
public interface IRestServiceImpl
{
[OperationContract]
[WebInvoke(Method = "GET", UriTemplate = "/GetStudentObj", RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json)]
Student GetStudent();
}
SVC
public class RestServiceImpl : IRestServiceImpl
{
public Student GetStudent()
{
Student stdObj = new Student
{
StudentName = "Foo",
Age = 29,
Mark = 95
};
return stdObj;
}
public class CustomUserNameValidator : UserNamePasswordValidator
{
public override void Validate(string userName, string password)
{
if (null == userName || null == password)
{
throw new ArgumentNullException("You must provide both the username and password to access this service");
}
if (!(userName == "user1" && password == "test") && !(userName == "user2" && password == "test"))
{
throw new SecurityTokenException("Unknown Username or Incorrect Password");
}
}
}
}
and Web.Config

</behavior>

Any suggestion??
It seems that you didn't set the custom behavior for your service.
You need to tell the service about your SecureRESTSvcTestBehavior behavior by using the behaviorConfiguration attribute:
<service name="RestService.RestServiceImpl" behaviorConfiguration="SecureRESTSvcTestBehavior">
<endpoint address="" binding="webHttpBinding" contract="RestService.IRestServiceImpl"></endpoint>
</service>
