Hi,

I am getting the following error message when I am trying to update the web service URL.

The vendor had changed the tags in their web service and asked us to update. When I tried to update the wsdl in order to generate the classes with updated tags

by right clicking under web reference and update web reference and getting the error.

Also tried to add the service just to try and still get the same error.

Using Visual Studio 2010

Here are the error details.

There was an error downloading <<vendor URL>>?WSDL'.

The request was aborted: Could not create SSL/TLS secure channel.

Metadata contains a reference that cannot be resolved:<<vendor URL>>?WSDL'.

Could not establish secure channel for SSL/TLS with authority '<<vendor URL>> without ?WSDL

The request was aborted: Could not create SSL/TLS secure channel.

Hi

Not sure exactly which group this belongs to. It's a question about ASP.NET and webservice authentication.

I have a Dynamics NAV Webservice that I use in my intranet solution (web solution). I want to access this webservice as the logged-on-user.

The website is using Windows authentication and when I enable impersonate it works fine on my computer both on IIS and IIS Express. I access the webservice as the logged on user (and not as the Application Pool Identity). Perfect!

System.Security.Principal.WindowsIdentity.GetCurrent().Name shows my username as it should. If I change impersonate to false, the WindowsIdentity changes to the application pool. As I expect.

Then I publish this site to another server on the same domain and the same setup gives me the error: "The remote server returned an error: (403) Forbidden." when connecting to the web service. So it seems this server is not passing on my credentials to the webservice for some reason. System.Security.Principal.WindowsIdentity.GetCurrent().Name still shows my username, as it should, so the impersonate is doing something at least.

Why is my computer using impersonate as I expect and the server isn't?

I have tried Kerberos and NTLM on the webservice, but both work on my computer and not on the server.

The webserver is running Win 2012 R2 with IIS 8.5

My local computer is running Win 10 1703 with IIS 10

HI All,

I never worked on any eCommerce/payment related web applications.

I have a web application based on .Net 3.5. Now I want some payment option so that user can use their credit/debit/internet banking for payment and the amount should go to manager's account. Manager's account may be a paypal/paytm/e-wallet or a simple bank account.

How can I add this module.

Please let me know any reference, link or any resource based on .Net framework.

Thanks

Hi there

The question is answered, probably, here:

https://blogs.msdn.microsoft.com/wenlong/2010/02/20/using-asp-net-sessions-from-wcf/

but that code is all around the OperationContext.Current, which is not NULL only for a given code example.

In my case the system creates all proxies automatically and all I do is calling things like:

LoginServiceReference.LoginClient wc = new LoginServiceReference.LoginClient();
LoginServiceReference.IDTWebUserDTO user = wc.DoLogin(model.Login, model.Password);

It works Ok, but as you may see, the LoginClient is created for me automatically. When calling wc.DoLogin there is no way to get into its context to obtain the OperationContext. For sure, I can modify the generated proxy, but next time the system will re-generate it. Bad approach.

For me the OperationContext.Current is always NULL here. How to get the ASP.NET session ID (as the blogger does in his InitialInvoke() method) and how to assign it (as in his Invoke2() method) ?

Maybe you can suggest other technics to maintain the ASP.NET session for WCF communication?

Thanks.

Hi,

I have created a simple wcf service. I have already debug the wcf service separately, it's okay then. I have hosted it by a windows service. But when I install the windows service in my computer and tried to start the windows service, it can't be start. It's getting the following exception.

Service cannot be started. System.ServiceModel.AddressAccessDeniedException: HTTP could not register URL http://+:8080/. Your process does not have access rights to this namespace (see http://go.microsoft.com/fwlink/?LinkId=70353 for details). ---> System.Net.HttpListenerException: Access is denied

Although I have started my visual studio as an administrator and also the visual studio developer command window during the service installation. I have also register the base address of the service by using the command "netsh http add urlacl url=http://+:8080/MyUri user=DOMAIN\user". None of those process can't solve the exception. Please suggest me a way to solve the exception.

I have developed an asmx web service that serves the data from the Oracle database to front end clients (clients are using .net based desktop application).

the number of concurrent clients will be 1000, service will be responsible for serving this client calls for not only retrieving data from the database but also performing some business login and manipulating data in the database server.

is it safe to use this asmx web service to handle such a number of clients? and will my service will be efficient enough to timely serve these # of clients?

How is it supposed to work?

Hello,

 I have created an application, with a layer that has multiple wcf(web services). Let's say WebService1, Webservice2, Webservice3, Webservice4, and Webservice5.

Webservice1, 2 and 3 can be called with same certificate. The issue is the caller to Webservice1, can also access Webservice2 and 3.

What I want is the caller to Webservice1, use only Webservice1 and be denied access to Webservice2 and 3, keeping same certificate.

What are the options?

Thanks in advance

I have been trying to create a service from a supplied WSDL for an API that we need to hook into. The way this works is that we have to create the service for the API to call into and send back information to the caller. I used svcutil to create the service contract and discovered that all the Action  properties were blank, which meant that it would not compile. This then lead me to this post https://docs.microsoft.com/en-us/dotnet/framework/wcf/samples/dispatch-by-body-element and on checking, I found that indeed the soapAction in the WSDL for all functions was blank. I added the three classes from the example link into my project , added the DispatchByBodyElementBehavior property, added a default method and set the other OperationContractAttribute properties as per the article. The service then compiles and runs. However, if I try and create a client for it from the service I created using Visual Studio or svcutil , it has no functions. Also if I use the WCF Test Client (by starting the VS project with the .svc file selected), I get an error message "The contract 'IViatorWCFService' in client configuration does not match the name in service contract, or there is no valid method in this contract." I have checked "always regenerate config when launching services" and refreshed but no change. The problem is possibly  to do with the wild cards for ReplyAction , which is what the article indicated was required. I have tried leaving a question ion the original article, but have had no reply. I have also contacted the supplier of the wsdl (Viator) but at this stage have not had any replies. The code for the interface is below. There are a bunch of other classes and properties from the WSDL, but I have not pasted those here. I am new to WCF , so I'm struggling to work out what he issue is

 Help !

Many thanks in advance

I want to ask you something. last year i worked company and 4 team working one Project.  when they publish web service, Data contract dlls were being loading Shared Data. Now when i was published all data contract dlls is not load in shared data. i dont remember exatly. when then copy shared dll's to MVC bin all dlls update automaticaly.  I think when i publish my Data contract as shared data everything will be done.  I'm sorry for not remembering what this team did. How can i configure web service for publish data contract  as Shared Data. 

Web create private company project. We use ASP.NET C# MCV tecnology.  Project using the web service when connect to the database. Now we keep going projectsmoothly. But when we changed web service code and copy compiled ddl to project bin directory, then projectdisown the changed web service dll. Therefore whenservice dll changed i always click Services / Update Service Reference button. For now i can click because project is run in my local computer. Following monts  we load the project to the remote server. In this case when we change web service dll we will always copy compiled project and web service ddl to remove server. I heard some people was configure their project for updated web service dll automatically. How can i configure my project for update web service dll automatically or what should i do

I need to send XML to a home grown web server on port 80 that "sort of kind of" understands XML serialization.  Will eventually need to be able to write to many of them at the same time. (up to 1000) 

The HTTP protocol for the home grown server is tight and not an issue, but I will need to use  their library for the XML parsing and serialization.

What library/approach for web should I use for the HTTP communication? 

thanks
