Turn on IncludeExceptionDetailInFaults either from ServiceBehaviorAttribute or from the serviceDebug configuration behavior on the server

Question

I have a WCF service that has been working perfectly  and something has changed and I don t know what   I get this exception      System ServiceModel FaultException  The server was unable to process the request due to an internal error   For more information about the error  either turn on IncludeExceptionDetailInFaults  either from ServiceBehaviorAttribute or from the  configuration behavior  on the server in order to send the exception information back to the client  or turn on tracing as per the Microsoft  NET Framework 3 0 SDK documentation and inspect the server trace logs    This is confusing because I am running  NET 4 0   Where do I turn on IncludeExceptionDetailInFaults  I m battling to find it

As the error information said first please try to increase the timeout value in the both the client side and service side as following     lt basicHttpBinding gt       lt binding name  basicHttpBinding ACRMS  maxBufferSize  2147483647        maxReceivedMessageSize  2147483647        openTimeout  00 20 00         receiveTimeout  00 20 00  closeTimeout  00 20 00        sendTimeout  00 20 00  gt         lt readerQuotas maxDepth  32  maxStringContentLength  2097152          maxArrayLength  2097152  maxBytesPerRead  4006  maxNameTableCharCount  16384    gt       lt  binding gt         Then please do not forget to apply this binding configuration to the endpoint by doing the following     lt endpoint address    binding  basicHttpBinding         bindingConfiguration  basicHttpBinding ACRMS        contract  MonitorRAM IService1    gt       If the above can not help  it will be better if you can try to upload your main project here  then I want to have a test in my side

If you want to do this by code  you can add the behavior like this   serviceHost Description Behaviors Remove      typeof ServiceDebugBehavior    serviceHost Description Behaviors Add      new ServiceDebugBehavior   IncludeExceptionDetailInFaults   true

Define a behavior in your  config file      lt configuration gt     lt system serviceModel gt       lt behaviors gt         lt serviceBehaviors gt           lt behavior name  debug  gt             lt serviceDebug includeExceptionDetailInFaults  true    gt           lt  behavior gt         lt  serviceBehaviors gt       lt  behaviors gt             lt  system serviceModel gt   lt  configuration gt    Then apply the behavior to your service along these lines    lt configuration gt     lt system serviceModel gt               lt services gt         lt service name  MyServiceName  behaviorConfiguration  debug    gt       lt  services gt     lt  system serviceModel gt   lt  configuration gt    You can also set it programmatically  See this question

You can also set it in the  ServiceBehavior  tag above your class declaration that inherits the interface   ServiceBehavior IncludeExceptionDetailInFaults   true   public class MyClass IMyService           Immortal Blue is correct in not disclosing the exeption details to a publicly released version  but for testing purposes this is a handy tool  Always turn back off when releasing

I was also getting the same error  the WCF was working properly for me when i was using it in the Dev Environment with my credentials  but when someone else was using it in TEST  it was throwing the same error   I did a lot of research  and then instead of doing config updates  handled an exception in the WCF method with the help of fault exception   Also the identity for the WCF needs to be set with the same credentials which are having access in the database  someone might have changed your authority  Please find below the code for the same     ServiceContract  public interface IService1        OperationContract       FaultContract typeof ServiceData        ForDataset GetCCDBdata          OperationContract       FaultContract typeof ServiceData        string GetCCDBdataasXMLstring             OperationContract        string GetData int value           OperationContract        CompositeType GetDataUsingDataContract CompositeType composite           TODO  Add your service operations here       DataContract  public class ServiceData        DataMember      public bool Result   get  set         DataMember      public string ErrorMessage   get  set         DataMember      public string ErrorDetails   get  set        in your service1 svc cs you can use this in the catch block    catch  Exception ex                        myServiceData Result   false              myServiceData ErrorMessage    unforeseen error occured  Please try later                myServiceData ErrorDetails   ex ToString                throw new FaultException lt ServiceData gt  myServiceData  ex ToString                 And use this in the Client application like below code     ConsoleApplicationWCFClient CCDB HIG service ForDataset ds   obj GetCCDBdata                 string str   obj GetCCDBdataasXMLstring                        catch  FaultException lt ConsoleApplicationWCFClient CCDB HIG service ServiceData gt  Fex                    Console WriteLine  ErrorMessage      Fex Detail ErrorMessage   Environment NewLine             Console WriteLine  ErrorDetails      Environment NewLine   Fex Detail ErrorDetails             Console ReadLine              Just try this  it will help for sure to get the exact issue
