WCF proxy generation using SVCUTIL

Question

Hi

I was trying to generate WCF service proxy using SVCUTIL. This was working perfect till recently. However, not sure if after upgrading to 4.5 framework when I try to generate proxy, I get the below errors. Service proxy generation works great with Visual studio.

I run SvcUtil from visual studio 2012 command prompt. Any ideas please.

Answer 1

I have encountered the errors above when trying to combine to svc endpoints into a single proxy.  Is this the case?  If so, you might find that the generated proxy is usable. 

The error indicates that the types have already been declared (notice they are base types from the framework and not types defined in your service).

Answer 2

Hi,

There is a single service for which I am trying to generate proxy. Based on the errors I can notice that the types were already defined. Not sure what can be the issue.

Is there any way that I can provide a fixed namespace for the generated proxy? Like all the types inside the proxy should be under XXX.YYY

Thanks

Answer 3

Hi Mallkarjun

Yes you can. You do this with the /namespace or /n option. This could also have been set in your "Add service reference" under "Advanced...". This might explain the difference in behavior.

ServiceModel Metadata Utility Tool (Svcutil.exe)

You can also try to exclute types.

/excludeType:<type>

Hope this helps.
