I created a service reference with VS to a soap service. Now the server is offline and I would like to build a simple server for testing purposes. I've already tried wsdl.exe with the wsdl file but didn't work because it couldn't reach the server.
Is there any simple way to acheive this? Of course, I'm not expecting any business logic to be magically created, just the structures and empty methods. Then I'll make it respond with dummy data.
In the folder [project]\ServiceReferences\[service reference name] you'll find two files: one .wsdl and other .xsd
The xsd file contains the information that wsdl.exe was trying to get online. So running:
wsdl /language:CS /serverInterface file.wsdl file.xsd
will create the interface for the service. Then, create a new Wsdl Service Library project, add the interface (the new .cs file found in the same folder than wsdl.exe) and add the correct attributes to the interface, methods and data objects (if there's any).
Creating the service class is easy now that you have the interface.

I have a WSDL file for a Web service created in java
I need to create an identical WSDL file in C#(asmx or WCF doesn't matter) .NET where the only existing web method implementation would be changed but keep the same signature though.
I always have different WSDL files which won't work for the client
EDIT
I ended up using WSCF(web service contract first) it seems the only solution out there
the resulting WSDL with some manual minor modifications seems quite similar to the original file.
Your approach is a little off. I interpret your question as
How to use a WSDL file to create a WCF service?
I have a WCF service. Contract for the service is defined using interface. The implementation is not yet created. I need to create WSDL and XSD corresponding to the contract. I will deliver the soforth generated wsdl to my team members. They must be able to create the interface from the wsdl and create the service. What are the approaches/tools for creating the wsdl and xsd from the C# interface which is used as the contract? Also, how to create the interface back from the WSDL? Do I need to provide both the xsd and wsdl to the developers or only the WSDL?
What is the best approach for WSDL interoperability?
Note: I have two services. One uses Data Contract. Second one uses Message Contract.
Note: I am using Visual Studio 2010 and .NEt 4.0
Reading:-
Generating a WSDL from an XSD file
Can you combine the WSDL and XSD data from a WCF service?
What tool can I use to merge wsdl and xsd file?
Providing the WSDL should be enough as the WSDL would have the reference to the xsd's using the import attribute.
When defining your bindings for your WCF service make sure you use BasicHttpBinding (follows BasicProfile 1.1) which is interoperable.
Also you would consider flattening your WSDL for your service to be highly interoperable as at times php and other java clients might need flat wsdl. If you are using .NET 4.5 then you have this as an inbuild option now else you can check this link on how to flatten your wsdl
I have a WSDL from a webservice for which I don't have the implementation.
In order to create a client app, I'd like to build a dummy implementation of this WSDL.
Is there any way to create either a WCF service from this WSDL or a oldschool web service ?
I only want the skeleton of the service (throw new NotImplementedException() is ok). Then I will implement a custom test behavior.

For WCF, you can actually do this for the most part. Just use svcutil.exe (or the VS Add Service Reference wizard) to add a reference to the service.
This will generate all data and service contracts, and then all you need to do is add a new class to your project that implements the service contract interface that svcutil generated (which is just a few clicks in VS).
You are given a WSDL and a sample soap message, is there a good tutorial or sample code in using that WSDL to consume a web service? Does the WSDL follow a certain format in order for which it can be consumed properly? I recall a web service in Java that I changed certain tags and attributes in order for this to work, is there a general convention for the formatting used in WSDLs?
I think this might be harder than #1. You are given a WSDL and a sample soap message. Is there a way to use that given WSDL and not the WSDL generated by C# web service when exposing a web service? Is there a way to somehow "override" the WSDL of the web service to the given web service? Are there any conflicts in formatting and compatibility of the WSDL that ought to be considered?
The quickest and most painless approach is simply to use svcutil to generate the code representing the WSDL. At that point the code produced can be used as a client to query an existing service or you can define a class implemeting the service contact. Once you have the .NET classes the SOAP message example will just serve as documentation.
the default usage would be want you most likely want
svcutil myRemoteService.wsdl
which will generate a a file named [servicename].CS file and an output.config containing the necessary WCF client bindings.
Not sure what you mean by overriding the WSDL as it is the published contract that the service honors. So if you want to change method signatures or behavior it will no longer work as the change will no longer conform to the WSDL.
I have the following class in Class Library: Artist, which is a POCO
Now I have a method in a web-service (which has a reference to the mentioned-above library) with a signature like this:
[WebMethod]
public int Artist_AddArtist(Artist a) {
//
}
When I try to consume this service from an application (that also has a reference to the mentioned-above Class library), the expected parameter of the Artist_AddArtist method is not Artist, but a new type of Artist that is being generated in Reference.cs which is a partial class that is auto-generated.
Thus since in my application I use, supposedly the same Artist class from the library and now the Web Service method expects this new auto generated type, I cannot pass an instance of it to the web-service.
How can I fix this issue?
Maybe switching to WCF services is an option for you. As far as I remember, with a WCF service, you can reuse the same types on ther server and client side.
This article explains how to migrate an ASMX web service to a WCF service.
You cannot, and should not, fix the problem.
Some others will tell you to do things like edit the generated file, but that's not a good practice (as the changes will go away as soon as the Web Reference is updated).
What you're seeing is by design. See Basics: How Web Services Work.
Briefly, when you use "Add Web Reference", Visual Studio downloads the WSDL file from the service, and uses the XML Schemas from the WSDL to create some proxy classes to represent the XML described by the schema. It also creates a proxy class for the service itself, having methods for each operation in the service.
The proxy data classes can serialize to the XML that the service is expecting to receive, and can be deserialized back from the XML that the server sends in reply.
One way to think of it is that you only have this problem because both client and service are .NET. If your client were written in Java, then you wouldn't be thinking of sharing classes.
Note that WCF can do this, if necessary. It introduces a dependency between the client and service (they both have to use compatible versions of the assembly containing the classes), but when you need to do it, the option is there. It's useful when there is behavior in these classes that must be used both by the client and by the service.
