May i know is there a way to add c# service reference into a react native project?
Thanks
Well, finally I added a new Web API layer to communicate with the service reference. Seems like that is only way to communicate with service reference.
Recently I found another solution that writing a SOAP function in a node.js. You can simply run npm install soap in your node.js and follow the soap documentation and it works like charm. This method can save a lot of time compare with the C# Web Service method.

Looking to create a web application that will modify a value in a database. When this occurs, I need a C# standalone application to recoginize this occurred and pull the value that was modified.
When the web app updates the DB, can I fire an event to the standalone app so that it can call a stored proc and pull in the new value? What is the most efficient approach to accomplish this task?
You could convert your standalone app to a WCF service then call the service (server-side) when the form that does your database update is posted.
If you don't want to convert your standalone app (or can't), a quick hack that would still use WCF would be a simple one-line WCF app that uses System.Diagnostics.Process.Start() to invoke your standalone app. Again, just invoke the service from your server-side logic after you've processed your database update.
I mention WCF as a solution because you're obviously already hosting your solution on IIS, that's exactly where you'd host your WCF app, and it's so darned simple to make WCF service calls from server-side code in .Net web apps.
Is in VS something like this? I need to create simple server connected to DB that will organize all data. I plan to use it for mobile app. This app will have its own, native grapic interface, so I don't need any HTML's in my project.
Why am I asking? Because when I create new web project, VS automatically creates some HTML&CSS files, all stuff that browser needs. But I won't use browser, I need siple console that will show some returned data.
Something like in node.js: single, one executable file.
What you probably want is a self-hosted ASP.NET Web API application. Self-hosted means that you are running your own, minimal web server, no IIS required. To accomplish this, take a look at this tutorial:
http://www.asp.net/web-api/overview/hosting-aspnet-web-api/use-owin-to-self-host-web-api
There are multiple ways to do what you're asking.
The easiest way is to start a WebAPI project: http://www.asp.net/web-api. You can basically provide nothing but service "endpoints" for your mobile UI.
The other way is to host your own endpoints in a Console application via the use of, say, a HttpListener object. That's setting yourself up for pain though. I would recommend the WebAPI route.
I have written a commercial WCF web service.
I would like to give the service to another person to test independent of the application that will be using the web service. This is because a third party is going to be building that app and we don't have access to it at the moment.
Another thing to remember too is that the person I want to hand this off to for testing is a non programmer. That is important.
So are there any tools out there that can subscribe to a WCF web service, and recognise what data needs to be inserted, and create a GUI to try out different combinations of data?
Thanks.
I typically use SoapUI for that purpose. You can also create test suits with it and it's free. Alternatively you can use the Microsoft WcfTestClient.exe that comes with Visual Studio since version 2008 I guess...
WCF Test Client (WcfTestClient.exe)
You can find the WCF Test Client (WcfTestClient.exe) in the following location: **C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE**
Using the WCFTestClient Tool to Test Service Operations
You can consume a web service with Office InfoPath, or write a simple test application in C#.
In general, you need to publish the web service meta data (normally as a wsdl end point) - this metadata should enable any client to get all the information needed to make calls to your web service.

Update:
From the comment, is appears that you need non programmers to be able to test your service and are looking for a user interface that can be used to work directly with your web service (and automatically adapt to changes). As far as I know, there is nothing built it that will do this for you (though the old asmx services created web forms that could be used).
So you are looking for application that will create UI for manual testing of your service? Not sure if something like that is available for free. SoapUI PRO is able to do that but in contrast to common SoapUI it is not free. Basic SoapUI version requires tester to write XML messages directly.
You should think about your requirement. You want tester without any programming knowledge to test artificat which is for programmers - not for end users. You probably have to buy some tool or write your own solution to support such test.
I'm going to use C# to read data from a few webservices. I've done that many times before, but those times I've had direct access to the webservices from my development machine.
In this project I've just been sent a .wsdl file, and a couple of .xsd files for the webservice they have in their local intranet.
I've seen that I can use "Add Web Reference", and point directly to the .wsdl file, so that a C# class is created.
But how can I really test it? I'd like to return some dummy data that I can visualize while I develop. Any tips for this situation?
Mock Webservice
From the above source, a .cs file can be generated by opening a Visual Studio Command Prompt and running something like the following:
wsdl /language:CS /namespace:Your.Namespace.Here
/out:Directory\To\Save\To\ /protocol:SOAP /serverinterface
finally-your-wsdl-file-here.wsdl
You can also try SOAP UI for mocking up service with ease. (Free web service testing tool)
Check:
http://www.soapui.org/gettingstarted/mocking.html
The svcutil.exe tool bundled with the Windows SDK (found at C:\Program Files\Microsoft SDKs\Windows\v6.0\Bin) is a nice command line tool that generates WCF client proxies. I've found this to be a good way to interrogate a WSDL. It'll create an interface for the service and then a proxy class that implements that interface. You can then mock up something else that implements that interface to facilitate testing.
It is easy to create your own server side stub. Assuming you want to do it with WCF, then go here. You can then add some basic logic to get your client working.
You can also use the legacy Web Service functionality via the WSDL tool's /Server option, though I recommend you use WCF.
You may also want to try a product like "Fiddler" (http://www.fiddler2.com)
It allows you to capture HTTP (or HTTPS) packets and send a fake automated reply file back as if the server had sent the response. I use it for my project and it works wonders when the test server goes offline (which is often). I take an old response packet, save it as a text file, then send it back again and the application I'm building has no idea it didn't come from the actual host.
I've also found this article very useful: https://ivangrigoryev.com/en/how-to-mock-a-web-service-in-dot-net/
It describes the steps needed, from downloading the WSDL file and to the creation of the test project:
Get WSDL somehow
In the VS Command Prompt:
wsdl /language:CS /out:C:\Downloads\ /protocol:SOAP /serverinterface C:\Downloads\webservice.wsdl
Create a new ASP .NET Web Application with an empty template
Add the file, generated on step 2, to the project
Add a new service to the project (Add -> New item -> Web Service (ASMX))
Change the class definition in the code for this added web service, so it implements the right interface, e.g replace System.Web.Services.WebService with yours.
Hit Alt+Enter and implement the interface automatically with stubs.
Hit F5, the service will run and your browser will open, copy the URL and use it instead of the real URL.
This works only in .Net Framework since .Net Core and .Net 5 dropped the WCF server support. But I found it acceptable to have the main project on .Net 5, but this mock service on .Net Fw 4.8
Is it possible to create a C# EXE or Windows Service that can process Web Service requests? Obviously, some sort of embedded, probably limited, web server would have to be part of the EXE/service. The EXE/service would not have to rely on IIS being installed. Preferably, the embedded web service could handle HTTPS/SSL type connections.
The scenario is this: customer wants to install a small agent (a windows service) on their corporate machines. The agent would have two primary tasks: 1) monitor the system over time and gather certain pieces of data and 2) respond to web service requests (SOAP -v- REST is still be haggled about) for data gathering or system change purposes. The customer likes the idea of web service APIs so that any number of clients (in any language) can be written to tap into the various agents running on the corporate machines. They want the installation to be relatively painless (install .NET, some assemblies, a service, modify the Windows firewall, start the service) without requiring IIS to be installed and configured.
I know that I can do this with Delphi. But the customer would prefer to have this done in C# if possible.
Any suggestions?
Yes, it's possible, you may want to have a look at WCF and Self Hosting.
Yes, it is possible (and fairly easy).
Here is a CodeProject article showing how to make a basic HTTP server in C#. This could easily be put in a standalone EXE or service, and used as a web service.
One technology you might want to check out is WCF. WCF can be a bit of a pain to get into but there's a great screencast over at DNRTV by Keith Elder that shows how to get started with WCF in a very simple fashion.
http://www.dnrtv.com/default.aspx?showNum=135
You could take a look at HttpListener in the .Net framework.
I would highly recommend WCF. It would fit very well into a product like you are describing. There are a good number of books available.
Sure, you can do that. Be sure to change the Output Type of the project to Console Application. Then, in your Main function, add a string[] parameter. Off of some switch that you receive on the command line, you can branch to ServiceBase.Run to run as a Windows Service or branch to some other code to run a console application.
This question is somewhat older but since I needed something similar some time ago it felt like this question is still relevant.
I wrote a small Rest-API with NancyFx and OWIN. OWIN is a standard interface between .Net applications and web servers. With OWIN it is possible to create a self-hosted WEB-API. Nancy on the other hand is
a lightweight, low-ceremony, framework for building HTTP based
services on .NET ยน
The combination of those two makes it possible to create a self-hosted C# Web service.
I am quite sure that there are many more possibilities to create something like this by now but since I used it like this I thought the Information might be useful to someone.
