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.

I am trying to install Sharepoint 2016 and have just been running into issue after issue. I have tried all suggested solutions available but have had no luck. Any clue why this is happning? The prerequisite installer (such a terrible and useless tool IMO) failed to install anything during the prerequisite installation process so I had to install the prerequisites manually. I tried reinstalling WCF data services 5.6 tools using the prerequisite installer in command line with the correct parameters and had no luck. I have tried reinstalling the .net 4.6.2 framework as well.

I am running a fresh install of Windows Server 2012 R2 and the database server is running Microsoft SQL Server 2014

Here is the error:

One or more configuration settings failed. Completed configuration settings will not be rolled back. resolve the problem and run this configuration wizard again. The following contains detailed information about the failure.

Failed to create the configuration database.

An exception of type Microsoft.Sharepoint.Upgrade.SPUpgradeException was thrown. Additional exception information: One or more types failed to load. Please refer to the upgrade log for more details.

I have also attached the error log. Any suggestions?

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

Hi Experts,

Quick question. Just followed this article here
http://bitoftech.net/2014/10/27/json-web-token-asp-net-web-api-2-jwt-owin-authorization-server/

I have tested with Postman but it doesn't really say how you can run the project on visual studio

any ideas as always will be helpful..

Thanks

I have a C# WCF Service which is hosted in IIS 8.5 and has a number of web services. One of these web services is called MobileRegistration and when called from the Client works correctly (see below)

using (var svc = new DCRulesServiceRef1.TransactionClient())
{string returnval = svc.MobileRegistration(enterpriseId, userId, deviceId, qrcode);}

Open in new window


However I also need to be able to call the webservice MobileRegistration directly via a URL without having to go through the client. The URL I created is as follows

http://xx.xx.xx.xxx/DCRules2Alias/Service.svc/MobileRegistration/?&userId=TESTUSER&enterpriseId=TESTENTERPRISE&deviceId=TESTDEVICE&qrcode=TESTQRCODE
This fails with HTTP400 Webpage cannot be found.

http://xx.xx.xx.xxx/DCRules2Alias/Service.svc  does return the TransactonService Service page successfully.  So why can it not find my service. Is the format of the URL incorrect for a WCF web service ? Below is some of the relevant code and WSDL. Appreciate if someone can point out what I am doing wrong

regards
Pat

Operation Contract for MobileRegistration web service
[OperationContract]
[WebGet(UriTemplate = "MobileRegistration?enterpriseId={enterpriseId}&userId={userId}&deviceId={devicerId}&qrcode={qrcode")]

        string MobileRegistration(string enterpriseId, string userId, string deviceId, string qrcode);

Hello
I have WCF service which emails invitation for members to join a particular enterprise. The URL sent to the users is as follows:

Please respond to invitation using the Link below:
http://www.tios.ie/account/invite.aspx?enterprise=AAAAAA&enterpriseName=BBBBBB&emailaddress=CCCCCC

This would take this to the Invite Page where they could accept or reject the invitation. This all worked fine until recently. However now when the URL is clicked, instead of going to the invite page , it seems to be trying to redirect to the Login Page. Nothing is displayed but the URL displayed on the browser is as follows:  

http://www.tios.ie/Account/Login.aspx?ReturnUrl=%2faccount%2finvite.aspx%3fenterprise%3dAAAAAA%26enterpriseName%3dBBBBBB....

I am not sure why this is happening or how I would go about debugging. Appreciate some suggestions.

Dears.,

Referring to some links, I could fix by changing in web config of my WCF to open WCF using https from IIS manager but in my application upon running it gives below error message when calling a method from WCF web services: The provided URI scheme ‘https’ is invalid; expected ‘http’.Parameter name: via

Any hint?

Besides , in order to let my WCF open normally, we recommend to adjust in web.config mainly in 3 parts below:

I dont want to re-invent the wheel and build a new WCF or Rest webservice. Please advise, how can I find out if the service I need has already been created by someone? I would love to be able to re-use that WCF/Rest service.

Example: I need a service that would convert currencies.

Thanks,
Ricky

All

We have a requirement where we need to build a WCF service which can make outbound calls (as client) to backend services which requires 2-way SSL (mutual-authentication).

We have been trying this with no luck. It works with 1-way SSL (WCF as client), but when we set the backend services to require 2-way SSL, the handshake failed at the point where WCF is supposed to send its certificate to the backend service, but it doesn't.

Any one has experience doing this? Any clues of what the problem could be will be much appreciated.

Best Regards
Charles

I have a class called "globals" which holds multiple classes that are use by my WCF application. So for example globals consists of up to 50 classes. Until now I have been defining classes with globals  as follows:

   public class Commands
    {
        DataSet ds = new DataSet();
        DataTable dt1=new DataTable("dt1");
        DataSet ds2 ;//= new DataSet("ds2");
        DataTable dt2; //= new DataTable("dt2");
        DataRow dr2;
        string[] delimitedList1;
        string[] delimitedList2;
        string[] delimitedList3;
        string[] delimitedList4;
        string[] delimitedList5;

        string currentDataType = null;
        string ds1XmlString = " ";
        string ds2XmlString = " ";
        string myStringValue = "";
        int cnt = 0;
        DataSet dsCopy = null;
        DataSet dsCopy2 = null;
        DataSet cltDS = null;
        DataSet dsSav1 = null;
        DataSet dsSav2 = null;
        DataSet dsSav3 = null;
        DataTable fileSchema;
        public Commands()
        {

        }

Open in new window


      globals g;

I now realize that by placing globals into class Commands that it is part of this class rather than a reference.I want to create class Commands and be able to reference variables that are available in globals without having to imbed globals as part of class commands. Appreciate if someone can explain how I can achieve this ?

Enroll in September's Course of the Month

This month’s featured course covers 16 hours of training in installation, management, and deployment of VMware vSphere virtualization environments. It's free for Premium Members, Team Accounts, and Qualified Experts!

I have a WCF Service written in C# which makes extensive user of global variables. The Service runs menus and transaction which are made up of sequenced database records with each database record capable of calling specific logic based on inbuilt commands. A typical simplistic example could be:

  05  Start
  10  Display Screen
  20  Input Range of Items
  30  run SQL statement to retrieve item details from Item master table
  40  Display Item Details
  50  Confirm selected Items
*60  Run SQL statement to report on Item Usage
*70  Output SQL results to CSV  
*80  Email usage report to user
  90  Goto Start

Those marked with * should run in a background thread so that after seq 50 the user will be returned to seq 05 whilst the background thread takes over. The issue I have is that Many of the variables controlling the transactions are global variables and so when the user returns to 05 and then exists to a new transactions this effects the background job since the background job is running the same code as the UI , except in the background thread.

I have copied all of the variables from UI to the background thread however the UI continues to update these global background thread variables after the background thread is launched. How can I stop the UI from affecting the background thread global variables ?

This app.config is resided in my c# class library. and I have class library called service.cs


I also have web application in c# and try to called service.cs (of course I added reference inside of the web app)
and I have alert about "Could not find default endpoint element that references contract"

so I create another web application project and add web reference directly and the webconfig is exactly the same. there is no error and I can call as usual.
What did I do wrong?
