Reference assemblies error in Win 8 Release preview metro app

Question

I am developing a Win 8 metro app using the Bing Search API for Azure data market. I have included the BingSearchContainer.cs  from the Bing Azure website in my app.  This class requires the reference to system.Data.Services.Client, so I have included this in the project. The reference assembly is from "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\System.Data.Services.Client.dll".

The app compiles successfully, but when I run the app, I get the following error.

"Could not load file or assembly 'System.Data.Services.Client, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. T
he system cannot find the file specified."

Any advise is greatly appreciated.

Hi,

You can look at following article on using OData for Metro Apps.

If the above article does not help then people at following forum definitely can help you.

Hi Touseef,

Thanks for the links.

The Bing Search API doesn't need to add a service reference in Visual Studio, I implemented this in Windows Phone 7 using the migration guide provided in the below link. They have provided a Proxy which can be downloaded.

https://datamarket.azure.com/dataset/8818f55e-2fe5-4ce3-a617-0b8ba8419f65

Also in the following example for Translator there is a Proxy provided and a Service reference is not required.

http://code.msdn.microsoft.com/Walkthrough-Translator-in-7e0be0f7

 The project needs System.Data.Services.Client which is used by the proxy, so this needs to be added a Dependency reference.  While this worked for me Silverlight (WP7), its not working in Metro. The above examples are for .NET/C# console applications.

 

Answer 3

You are correct, we need to update our generated proxy classes to work with Windows 8 Metro and new OData classes.

Let me check when we can do this and get back to you.

Thanks,

Answer 4

You can also manually request the REST API and manually deserialize the result. You may want to use JSON format so that you can use Json.NET to help with the deserialization.

In addition, here's a good reference:

One update to the blog: you need to add Microsoft.Data.OData.Metro.dll to references as well (from same directory) in VS 11 July update.

Thanks,

Max

Answer 6

Thanks Max and Arwind.

I will try it out and update this thread.

Answer 7

Hi Max,

I can't find the Metro folder under \bin. The only folders available are .Net and Silverlight.  I have installed the WCF Data Services 5.0 for OData V3.  Is the Metro version publically available?

C:\Program Files (x86)\Microsoft WCF Data Services\5.0\bin\Metro\Microsoft.Data.Services.Client.Metro.dll

Thanks

   

Answer 8

It should come by default with VS 11 July update for Release Preview.

Do you install Ultimate?

Thanks,

Max

Answer 9

No, I am using VS 12 Express 2012 RC for Windows 8. I can't find the Metro folder under \bin.

C:\Program Files (x86)\Microsoft WCF Data Services\5.0\bin

Answer 10

The library works only with VS Pro at this moment.

Thanks,

Max

Answer 11

Hi,

In the RTM Win 8 and Visual Studio 2012, the Metro folder in no longer under \bin. Is there an equivalent for Metro Apps (Windows store) - Microsoft.Data.OData.Metro.dll  ?

C:\Program Files (x86)\Microsoft WCF Data Services\5.0\bin

Answer 12

Just ran into exactly the very same issue on my app.

Added Microsoft.Data.Services.Client (different file name, contains the same namespace as the old one), Microsoft.Data.Services, Microsoft.Data.OData.

Then, requested for System.Configuration as in:

---

Cannot resolve Assembly or Windows Metadata file 'System.Configuration.dll'

Xaml Internal Error error WMC9999: Type universe cannot resolve assembly: System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a.

---

So, I added then System.Configuration from C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5, v4.0 and v3.5. In all cases I get:

---

C:\Program Files (x86)\MSBuild\Microsoft\WindowsXaml\v11.0\Microsoft.Windows.UI.Xaml.Common.targets(255,9): Xaml Internal Error error WMC9999: Cannot find type System.ServiceModel.Web.WebServiceHost in module System.ServiceModel.Web.dll.

---

The only dll that contains the requested type (System.ServiceModel.Web.WebServiceHost) is C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.5\System.ServiceModel.Web.dll, but I cannot add a reference to it. VS11 says that it is automatically referenced by the build system.  But, I bet that it is referencing the version 4 or 5 of the same, none of which contains the required class.

Ran into a wall :(

Answer 13

Found the right version, was released separately from the main VS11 package for the RTM version.

It is at: http://www.microsoft.com/en-us/download/details.aspx?id=30714
