Web service, REST interface, WSDL, ASMX, C#

Question

Web service, REST interface, WSDL, ASMX, C#

Markus Freitag 3,791

I think it is important to mention that you tagged this post as ASP.NET Core and this question is ASP.NET not Core. Secondly, ASMX is a very old technology. If you need a JSON response then create a Web API project.

I need to connect to a customer who has a WebService. From this customer I get a WSDL file. Not an executable server. The idea is to write a mock server.

What is the current technology? What would I have to request from the customer? Which file? How can I easily include this in my client C# desktop application.

Thanks for tips. Thanks for a server and a client sample

The WSDL (Web Service Definition Language) is an XML file that documents request and response types as well as the remote method signatures. Read the WSDL and write the method stubs. If you are looking for a code generator to produce method stubs from a WSDL, then do a Google search and find a utility that best fits your needs. Adding a service reference or using the wsdl.exe or svcutil.exe will generate the request/response types. Just copy the types to the mock service project.

create stubs from wsdl c#

What is the current technology?

WSDLs document SOAP (XML) services.

What would I have to request from the customer? Which file?

Again the WSDL file. Service owners generally expose a testing site. Contact the the service owner for support as they know their systems and can guide you far better than a ASP.NET support forum.

How can I easily include this in my client C# desktop application.

It is a matter of learn the fundamentals. If the service owner has a test site then create a service reference as explained in your other thread using Visual Studio. If the service owner only provides an out-of-band WSDL which is atypical then use the wsdl.exe or svcutil.exe to generate the C# source. Both utilities let you select an output location. Read the documentation!

ServiceModel Metadata Utility Tool (Svcutil.exe)

Adding code to an ASP.NET Visual Studio project is very easy. Just copy the files using Windows Explorer to a folder in your project or if you used the code generators make sure the output is a folder in your project.. If you cannot see the files in solution explorer, then right click and highlight Add -> Existing item... Find the file(s) and click ok.

For ASP.NET Core projects just add the files to a folder in the project.

Thanks very much. It is so complicated. There is a Youtube instruction video.
Which setting are to be made where. The other problem is not solved.
Get it to work without Visual Studio. Do you still have an idea for the cause? Use my other thread.

Or Do you have a server, client test application?

I need a C# Desktop Client, no ASP or Web.
I will connect from C# to the server.

As far as I can tell you did not follow the instruction in the other thread. http://localhost:52683/ is the application root. IIS expects a default document otherwise IIS thinks the client is trying to fetch a directory listing. Displaying a directory listing is turned off by default in IIS. This is what the error message is telling you.

Add an index.html or default.aspx page in the project root. Add a link in the index.html or default.aspx markup that open the WebService.aspx page. You can add WebService.aspx as a default page in IIS which is a little odd but it would work.

I need a C# Desktop Client, no ASP or Web.

Creating a service reference or using wsdl.exe or svcutil.exe has nothing to do with the project being ASP. How did you come up with this notion?

From my perspective you are not taking the time to learn the fundamentals and expect this forum to be a an educational service that will find content that you understand. We have no idea of your experience level or how you learn.

yes, do you know a good youtube instruction video? Or a good project?

I've proved sample code, detailed steps, and links to reference documentation. I don't have time to find videos and projects to further your learning. I'll leave that bit up to you.

Hi @Markus Freitag

You can use some tools like Postman to achieve this. You can make requests that return mock data defined within Postman if you do not have a production API ready, or you do not want to run your requests against real data yet. By adding a mock server to your collection and adding examples to your requests, you can simulate the behavior of a real API.

Hope this resolves your Query!!

Hello,
you mean that? https://www.postman.com/

I think, that is free, but needs time for understanding too. www.soapui.org

Do you maybe know a good video about how I would have to configure it?

If you have the .wsdl file then you'll just need to add the Service Reference to your solution described here:
https://learn.microsoft.com/en-us/dotnet/core/additional-tools/wcf-web-service-reference-guide

This will generate a C# service reference that you can instantiate, configure & proxy your requests through. You'll just need the service address (which will be a URI ending in .svc) to configure your reference.
