I have a service dll, which has a reference to System.Web.OData (from Microsoft.AspNet.OData.5.9.0)
The service dll has an exposed method which takes in an OData.Delta<>
This service dll when compiled is ilmerged, so it has this "version" of Data embedded.
Now the consuming application, also has a reference to the same OData, however, it comes from a corext, globalized cache.
However, when the consuming application, attempts to call the method that has an OData.Delta<> parameter, it complains that it cannot convert from ConsumingApp.OData.Delta to ServiceDll.OData.Delta.
How would I go about making sure that the parameter uses the actual proper "version" of OData.Delta so that they do not conflict?
I can't seem to find like.. a NameSpace.For.ServiceDll that would enable me to specifically target the OData.Delta that is embedded in the ilmerge
you have to install ms odata client for visual studio create a new odata client class, an add in http uri metadata de correct http. After that click on the file and run custom tool option download de latest metadata
Sorry I understood that had problems with odata schema. The error you expose, if I understood well you are using ilmerge for combine various project and reference again the library combined. I think:
you can add the namespace with a surname, for example:
import reference1 = microsoft.data;
import reference2 = ilmerge...;
so you can use them in code like reference1.class1 and reference2.class1
Hope this help you
When a Web Reference is added in Visual Studio the generated proxy class automatically uses a default namespace which consists of the application’s default namespace together with the web reference name. the problem is i have a profile web service which all my projects use that in order to authenticate. Because of the namespace i cant add a profile class as a link. Now I wonder if there is any way to manually set the Reference name? (or maybe there is a better way which could solve my problem.)
So far I've found this:
1- Go to the service Reference.cs and then rename the namespace.(the problem is every time i update the service the namespace goes back to the default)
2- I found this :Manually setting the namespace for a web service proxy class in Visual Studio(the problem is i have to change the build event which it could cause the unexpected errors.)
Use "Custom Tool" option with wsdl.exe and give the required parameters. Whenever you want to update the service reference run the custom tool by using below mentioned option.
/n[amespace]:namespace

i have few project that use the same wcf service, my asp.net and test project are working fine
with the wcf service i add.
my new project in mvc asp.net also added the wcf reference , all of those project reuse
the assemblies.
when there was compiler error with the types i saw difference in the reference.cs file and
the order that visual studio generate the code wasn't the same.
// CODEGEN: Parameter 'GetLookupTablesResult' requires additional schema information that cannot be captured using the parameter mode. The specific attribute is 'System.Xml.Serialization.XmlElementAttribute'.
this is the working one:
Runtime Version:4.0.30319.18063
this one not generate :
Runtime Version:4.0.30319.18444
why there is difference ? is it something in the solution settings?
When I use the "Add Service Reference" utility in Visual Studio to connect to a WCF Data Service (OData), visual Studio doesn't generate an App.config file with the System.ServiceModel section for me. (The proxy class is generated fine). Is this normal?
Is there still a way to have this config generated automatically? The WCF service in question is secured and I therefore struggle with authentication issues if I try to to use the command line svcutil.exe with the /config option.
svcutil.exe cannot be used with WCF Data Services (OData), there's a datasvcutil.exe which is used instead.
The Add Service Reference for OData should not generate anything into your app.config as it doesn't need it. To use it, you just new up the generated context class and pass in the URI of the service.
If your OData endpoint required authentication though, the Add Service Reference doesn't support that though, so I'm surprised it works for you.
I have a Windows Service Solution and am trying to add a service reference to a Hermes(Opensource ebms message server) Web Service in VS2010.
I can find the Web Service using it's URL, but when I try and populate the Service reference I get the following errors in Visual Studio:

Some investigation seemed to suggest it is due to svcutil.exe not been able to build the proxys due to not having permissions to a directory (possibly c:\windows\temp). I have tried assigning various access permissions, but I am not really sure which user needs the permission, or if it is just a red herring.
Any ideas would be greatly appreciated.
Thanks
Have to uncheck the Reuse types in all referenced assemblies from Configure service reference option
Check this for details
Right click on your service reference and choose Configure Service Reference...
Then uncheck Reuse types in referenced assemblies
Click OK, clean and rebuild your solution.
I also encountered a similar error when trying to generate the client for a web service from an ASP .Net MVC 4.0 project using Visual Studio 2012.
The root of the problem seems to be that fact that the project from where I was trying to generate the client was referencing an assembly which in turn was dependent on another assembly that was not being referenced as well.
When "Reuse types in referenced assemblies" is enabled in the service configuration, the service generator is probably inspecting all the referenced assemblies to get a list of types that can be reused. The fact that one of the referenced assemblies is referencing another assembly which is not available is probably causing the generator to fail.
Unchecking "Reuse types in referenced assemblies" from the service configurations will solve the above problem, but there is a side effect to it. The reuse types option is there for a reason and in some cases it avoids unnecessary casting in the code consuming the service.
For example, if the service itself is built using WCF and some methods parameters inside it are of type System.Guid, they will be translated to strings in the generated client if the reuse types option is disabled.
An alternative that I prefer to disabling reusing types is to add the service reference from Class Library project specifically created for that purpose. The one thing to keep in mind is to copy all the service related configurations from the class library's app.config to the configuration file of the startup project.
If there are types defined in local assemblies that need to be reused in the service client, those assemblies simply need to be referenced from the above mentioned class library project, along with all their dependencies.

Thanks to the article above.
In my case, i have this issue with my WPF project in VS.Net 2008. After going through this article, i was realizing that the assembly used in the web service is different version of assembly used on client.
It works just fine after updating the assembly on the client.
It would be extremely difficult to guess the problem since it is due to a an error in the WSDL and without examining the WSDL, I cannot comment much more. So if you can share your WSDL, please do so.
All I can say is that there seems to be a missing schema in the WSDL (with the target namespace 'http://service.ebms.edi.cecid.hku.hk/'). I know about issues and different handling of the schema when include instructions are ignored.
Generally I have found Microsoft's implementation of web services pretty good so I think the web service is sending back dodgy WSDL.
Restarting Visual Studio did the trick for me. I am using VS 2015.
I get the same error in Silverlight 5 (VS2012)
You can also remove the references to:
System.ServiceModel.DomainServices.Client
System.ServiceModel.DomainServices.Client.Web
After you've updated the service references, be sure to add them back in.
As stated above, there are a couple of different problems possible. What we found is that the .DLL for the WCF library had been added as a reference to the client project. This, in turn, created problems with resolving the objects and thus caused the files to be "emptied" by code generation steps. While unchecking the use "Reuse Types..." can seem like an answer, it creates extra definitions of object types, which are proxies to the real types, in a new name space, which then causes all kinds of "compatibility" issues with the use of those types. Only if you really want to "hide" a type should you check this option.
Hiding the type would be appropriate when you don't want a "DLL" type dependency to "leak" into a project that you are trying to keep segregated from another. If the DLL for the WCF library project creeps into the client project references, then you will have this problem with all kinds of strange side effects since the type definitions are also in the DLL.
face same issue, resolved by running Visual Studio in Admin mode
I have encountered this problem when upgrading a VS2010 WCF+Silverlight solution in VS2015 Professional. Besides automatically upgrading from Silverlight 4 to Silverlight 5, the service reference reuse checkbox value was changed and generation failed.
"Reuse types" is not always the problem when this error occurs.
When adding a reference to an older service, click 'advanced' and there 'Add Web Reference'. Now link to your wsdl and everything should be working.
If you want to correct this without uncheking the assembly reuse checkbox this is what worked for me:
Remove referenced assembly that you want to re-use
Delete all the bin folder of the project
Update service reference
Keep "Reuse types in specified referenced assemblies"
Add reference to assembly again to fix the errors
Update service reference again
I had this problem when trying to update my service reference (The error only shows up when adding a service reference though) but didn't want to remove the assembly reuse checkbox.
What worked for me was the following:
Remove referenced assembly that I wanted to re-use
Update service reference
Keep "Reuse types in specified referenced assemblies"
Ignore the errors, it's because the reference is missing!
Add reference to assembly again to fix the errors
Update service reference again
Voila, now it actually updates and doesn't try to remove all of my generated code anymore.
I was almost ready to give up on the re-use types feature...
EDIT: Also make sure that the build config is AnyCPU or x86, since svcutil is buggy with x64.
To the downvoter: Sorry if it didn't work for you, I don't even know why it worked for me, but it did. I may have done something else that time that fixed the problem, but no way to know now.
