How to pass an observablecollection to the client?

Question

I have an operationcontract which returns a collection say observablecollection<Product>. But when I generate the proxy on client, I get Product[] instead of observablecollection. So, is there any convient way to avoid that?

Answer 1

Please try the following

svcutil /rct:System.Collections.ObjectModel.ObservableCollection YourWsdl

For more information please see svcutil /?

Hope this helps

 

Answer 2

yes, I get it.

Answer 3

Hi,

I am trying this on the Jan CTP and I get "no type could be loaded for System.Collections.ObjectModel.ObservableCollection"

If I referance C:\WINDOWS\microsoft.net\windows\v6.0.5070\WindowsBase.dll

It still breaks

Any clues?

Hi,

I am running the following.

 svcutil /d:ServiceProxy /r:C:\Progra~1\Refere~1\Microsoft\WinFX\v3.0\WindowsBase.dll /rct:System.Collections.ObjectModel.ObservableCollection test\bin\Debug\test.dll

Where test.dll is my service contract.

 I get the following.

 Error: No type could be loaded for the value System.Collections.ObjectModel.ObservableCollection passed to the /referenceCollectionType option. Please ensure that the assembly this type belongs to is specified via the /reference option.

 It’s loading the WindowsBase.dll ok; if I break the path it gives me a Fusion error so I know it’s loading the assembly ok.

Hi,

I after a lot of trail and error I run into this post

When applied to WPF OC you need to use

/rct:System.Collections.ObjectModel.ObservableCollection`1 /r:C:\Progra~1\Refere~1\Microsoft\WinFX\v3.0\WindowsBase.dll
