WCF

Windows Communication Foundation (WCF) is a tool used to implement and deploy a service-oriented architecture (SOA) to support distributed computing where services have remote consumers. It features a runtime and a set of APIs in the .NET Framework for building connected, service-oriented applications. Services typically have a WSDL interface (Web Services Description Language) that any WCF client can use to consume the service, regardless of which platform the service is hosted on. WCF implements many advanced Web services (WS) standards such as WS-Addressing, WS-ReliableMessaging, WS-Security, RSS Syndication Services, WS-Discovery, routing and better support for REST services.

Hello,

I am trying to call a WCF Service from Jquery.
When i run the application as of now, it goes into error.
All i get is :         XHR: [object Object]

Earlier i was getting CORS issues.
I Included "            "Access-Control-Allow-Origin" under Application_Beginrequest of global.asax file.


Just to make sure the service is working good, I tried calling the service from a server side button control click and it works good and returns the data.
However, when i call it form Jquery, it goes into error and does nothing.

Can you point out what is wrong with this code?  Why is it failing.

I have a silverlight app hosted on windows 7 and IIS, it works fine

I'm trying to move to a different box (windows 10) and its not working
I've run fiddler tool and can see the SVC binary requests are not found (404)
As this is a direct copy of the published code, I assume its setup related
If i run the project through visual studio it works fine, but in IIS does not

Here is an example of the url that isn't found on the new box:
http://localhost/MasterUI/ClientBin/MasterUI-Web-GuiViews.svc/binary/GetV_gui_TempAlarmGraph_by_Site?site=0001&ent=FFFFFFFF
The above gives a 404 in fiddler

The previous request to the XAP file works and does NOT 404
http://localhost/MasterUI/ClientBin/MasterUI.xap

I've tried to duplicate the IIS setup as much as possible, but for some reason it isn't working

My solution consists of 2 projects
MasterUI (silverlight stuff here)
MasterUI.Web (this is the non silverlight app - .aspx files)


The windows 10 box is a fresh install, so perhaps i'm missing some components, but as its working in visual studio on this windows 10 box, I assume it's IIS setup related?

I have a .NET WCF service which communicates with a time and attendance clocking terminal.
The WCF service method is as follows:
   
[WebInvoke(UriTemplate = "/Status", Method = "POST")]
public Stream Status(XmlElement status)
{
   
    XmlDocument xml = new XmlDocument();
    xml.LoadXml(status.OuterXml);

    string terminal = xml.SelectSingleNode("/StatusResponse/@terminal").Value;
    string uid = xml.SelectSingleNode("/StatusResponse/@uid").Value;

    StringBuilder builder = new StringBuilder();
    builder.Append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
    builder.Append("<OperationStatus uid=\"" + uid + "\">OK</OperationStatus>");

    return new MemoryStream(Encoding.UTF8.GetBytes(builder.ToString()));
}

The WCF service is choking on ascii characters (ASCII 31) which are contained within the XML being sent from the terminal.
There is an error in XML document (3, 55), this is the ASCII 31 character after SR00 in the XML.

It is not possible to change the firmware on the terminal so I need to modify the WCF service to cope with the ascii characters.
If need be the ascii characters can be removed, however this must be done by the WCF service and not the client.

Aside from removing the TransactionScope created on the WCF client (and effectively taking msdtc out of the picture), Is there an alternate way to avoid the excessively long WCF-service-wide hang when a single workstation hosting the WCF client is misconfigured (or experiencing communications issues)?

We have a simple WCF service implemented using C#, and a simple WCF Client which creates TransactionScope before invoking the WCF service proxy.

Both work fine as far as concurrency goes if Windows Firewall allows TCP communication from/to msdtc.exe thru firewall. However if a single workstation is misconfigured (i.e. has firewall enabled, and has an Inbound Rule for TCP for msdtc.exe disabled), its attempt to communicate with the service will block all other WCF clients (which are properly configured) from communicating with the WCF Service for at least 41 seconds (given the currect settings for TCP retransmissions), despite us using much shorter timeout settings for the WCF binding as well as for the TransactionScope timeout.    

 The WCF service is decorated with
    [System.ServiceModel.ServiceBehavior(
        InstanceContextMode = System.ServiceModel.InstanceContextMode.PerCall,
        ReleaseServiceInstanceOnTransactionComplete = false,
        ConcurrencyMode = System.ServiceModel.ConcurrencyMode.Multiple,
        IncludeExceptionDetailInFaults = false,
        TransactionTimeout = "00:00:13"
       )
The WCF service has a single operation contract, …

1. RetrieveData is working fine., but now I want to assign class library value in a loop.
Basically, I have wcf call to get the list of name which is exactly same as class library property name - see newretrievedata
Is it possible to do that?

On another side of class library in c#, i already have all of the property/object in class library.

I am using WCF callback services for Real-Time User availability and text/video chat application and i have included reliable session with a receive timeout of 10 mins.The problem i face is when a message has to be broadcast for all users(say 10 users) i am using a for loop and if a client has disconnected from internet on his side the loop waits for 10 mins to reach the same client without broadcasting the message to other clients.
 Is there any alternative or a better approach for accessing other clients in the meantime or any work around.

Client javascript calls aspx.vb. VB code behind which then calls a WCF data contract that returns data from an SQL data base. That data is then serialized and inserted into a response.write() method.

 It fails. No exceptions, no errors, nothing.

 After the WCF HTTPS call, the response.isClientConnected property is getting set to 'false'. Making the HTTPS call to the WCF service is making the response.write lose it's connection to the client that called it.

 Any ideas to get around this?

What I have tried:

1 -  I have taken the data returned from the WCF call, and pasted it as a string in the response.write("").

      If I then comment out the WCF HTTPS call, it works fine.

2 - I've tried moving the function that calls the WCF out of the aspx.vb that has the response.write.  No change.

https://old.filofax.co.uk/index.php/api/v2_soap/index/?wsdl=1

Error message is attached(error1)

I have also tried to generate a proxy class using the same error message.

My issue is that I can browse to this URL ok.

I would appreciate any help. I have contacted the hosting company and they don't have any iea.

Hi, I am looking for some guidance in relation to WPF & WCF!

I currently have a  niche Point of Sale application that is written using Winforms and communicates to a ASP.NET web service. Whilst this currently works well. I am starting to reach the limits with the Winforms.  I am starting to plan the next major release of the software and I am thinking now is the best time to re-develop using more modern technology.

I am a self taught developer and whilst I have managed to produce a very stable application, I know I could have done things very different.

What I am hoping for is for some guidance on what i should and shouldn't do  this time around in the new WPF & WCF project.
If anyone is interested, my product can be found at pawnit365.com.au

The current application makes use of Tabs, and I want to continue to do this as its very popular. Users like it. However at the moment tabs are only limited to 1 instance of a tab type. Id like to allow users to have multiples of the same tab open at once.

Any help anyone is willing to offer or provide would be greatly appreciated.

Hi there,
We have a customer who is using a software provider who's product is hosted in the cloud. Basically the customer has a reporting tool that they would like to connect to the back end of the software to interrogate and pull data out. The software provider wont allow this, but they are going to setup a WCF service which pulls the data out of their SQL server, and makes it available to the customer. What we need to do is create a WCF client that can connect to the WCF service, and pull the data out (ie daily), and then we would like to store the data in a local SQL DB, where the reporting tool can interrogate. Any thoughts / tips on this?

I have a self-hosted VBNet database application that utilizes WCF.  It communicates with another WCF application.  When the first application is running in the debugger on a Windows 10 machine, it refuses to allow connections.  Running in the debugger on a Windows 7 machine does not cause this problem nor is the problem present in release mode regardless of the OS.  Any suggestions to solve this problem would be appreciated.

I currently have a C# WCF Service hosted in IIS 8.5  which allows users to print labels. Because the label printers are local printers for each user (USB connection on their laptops) they are forced to open the label in their browser and then click print on each label to print to local label printer. What the users want is for the labels to print automatically without any user intervention but without the printers being networked this does not seem possible - or is it?

Is it possible to use FTP to drop the text files (labels) directly onto the label printer spool queue of the laptop requesting the label?  The Service will have the IP address of each logged in user  but how can I send a file to a spooler rather than a folder and if it can be done can it be done silently ,without any user interaction.

I notice that when I send a label manually to the USB printer on the laptop (Windows 7 64bit) there are two files populated into c:/windows/system32/spool/PRINTERS. a SHD file type and a SPL file type. Is there any way of generating these two file for  the label text file to be printed?
 
I assume that a common FTP Site would need to be configured on each laptop for this to work. Appreciate any guidance and/or examples I can get.

regards
Pat

WCF

Windows Communication Foundation (WCF) is a tool used to implement and deploy a service-oriented architecture (SOA) to support distributed computing where services have remote consumers. It features a runtime and a set of APIs in the .NET Framework for building connected, service-oriented applications. Services typically have a WSDL interface (Web Services Description Language) that any WCF client can use to consume the service, regardless of which platform the service is hosted on. WCF implements many advanced Web services (WS) standards such as WS-Addressing, WS-ReliableMessaging, WS-Security, RSS Syndication Services, WS-Discovery, routing and better support for REST services.
