I am migrating a .NET GUI application built in .NET 1.1 to .NET 4.0. The application uses WSE 2.0 for web service communication. Web Service Comm. Module contains web service proxy and other class files implementing asynchronous functioning. The module sits between .NET GUI application and application Server hosting Web Services. Application Server has been implemented in non-Microsoft technology and the migration project should not change the server and the web services.
All the classes and forms in .NET GUI application call synchronous methodName of web service proxy class. Web Service Proxy derives from a custom class which in turn derives from Microsoft.Web.Services2.WebServicesClientProtocol. The custom class overrides “Invoke” method. Method “BeginInvoke” is called inside overrided “Invoke” method. Therefore even though application classes and forms are calling synchronous methodName , finally the web request goes as asynchronous.
Overrided “Invoke” method and the custom class enable to display dialog window with Cancel button for cancelling web request.
Proxy class in WCF has following implementation for a web method call. Is there something in WCF which can allow to customize functioning of call Base.Channel.MethodName(input)? Basically something which can allow changing synchronous web method call to asynchronous at run time?
[System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)]
getNewCustomerCodeResponse iAccountService.getNewCustomerCode(getNewCustomerCode request)
{
return base.Channel.getNewCustomerCode(request);
}

How do I call method of .net web forms service from .net core application?
I want to call controller's method (.cs class).
You have two ways to achieve it.
First, you can register an IHttpClientFactory and use it to configure and create HttpClient instances in your .net core application.
More details, you can refer to this.
Another way is using ajax to make get or post request to controller's method in js.
I am having a Duplex WCF Service hosted on console. This is tested and worked fine.
I want to consume this WCF service in Asp.net Core. I have done this using this https://medium.com/#narinkaew/using-wcf-soap-services-in-net-core-fb13180c4eda Consume WCF in Asp.net Core.
I am able to get response, but I am not getting any callback. Its just keep waiting.
I have uploaded the Code https://filebin.net/pf9eplqjncc0octj.
ClinicWcfService - is wcf Service Application
HospitalServiceHost - WCF Service Hosted on Console
ServiceEngineersDesk - is Asp.net Core Application.
Can someone tell me how to get a WCF callback in asp.net core application?
I have done this from my side.
Instead of creating instance of interface of the wcf service, create a instance of interface implementation.
Now this class exposes the event of the callback. Just subscribe to it
After a some struggle i was able to found out.
I have Windows Workflow Service developed in 4.6.2.
Is it possible to Invoke Window Workflow Service using HttpClient?
I have client application in .Net Core, and we cannot create WF service proxy in .Net Core application. (It's not supported currently)
However .net core has HttpClient class and I would like to know if can use HttpClient to invoke methods of Windows Workflow Service?
There is a VS extension for generating your proxy https://blogs.msdn.microsoft.com/webdev/2016/06/26/wcf-connected-service-for-net-core-1-0-0-and-asp-net-core-1-0-0-is-now-available/
I am new to WCF Service. I read that both ASP.NET and WCF Services are synchronous by default. However we can implement both the ASP.NET and WCF Services asynchronously. I want to know whether the generated Web Service Client (Proxy Class) is synchronous or asynchronous by default ?
The default is synchronous.
If you want the async method signatures, too, you need to either specify /async for svcutil.exe
C:\> svcutil (some URL here) /async
or you need to check the Generate asynchronous operations option in your Add Service Reference dialog in Visual Studio.
And of course - once you have generated the async methods, you also need to call those, obviously..... (they are called Begin(YourMethodName) and End(YourMethodName) for each of your service methods)
I have an application service layer (which all return serializable viewmodels). Some of these app services need to be callable via AJAX by client code in the Web UI. I'm currently wrapping them in ASMX files that do nothing but dictate the response format as JSON delegate each call to the application service class with the same signature.
Is it advisable to try to save a few lines of code by exposing the appropriate application service classes as WCF services? Can someone point me to an example? Any potential pitfalls for usage in WebForms client code?
Microsoft now considers ASMX services to be "legacy technology". You should not use them for any new development. They have been completely replaced by WCF. For instance, see the top of this article: http://msdn.microsoft.com/en-us/library/bb885203.aspx:
This topic is specific to a legacy
technology. XML Web services and XML
Web service clients should now be
