Hi, there is i guess a complete mess with Dynamics CRM Sdk and WCF Data Services.

Class Xrm generated by CrmSvcUtil.

We have this

class XrmServiceContext : Microsoft.Xrm.Client.CrmOrganizationServiceContext

but Microsoft.Xrm.Client in which CrmOrganizationServiceContext remains

has reference to

System.Data.Services, Version=4.0.0.0

so when compiling I get

Error 56 The type 'System.Data.Services.IUpdatable' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Services, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. ... Xrm\Xrm.cs 321467 23 Xrm

Error 55 The type 'System.Data.Services.IExpandProvider' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Services, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. ... Xrm\Xrm.cs 321467 23 Xrm

Error 57 The type 'System.Data.Services.DataService`1<T0>' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Services, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. ...\Xrm\Xrm.cs 328709 23 Xrm

As you can imagine The Mess is complete!

Any one have a clear vision what I have to do ?

Hi,

You simply need to add a reference to System.Data.Services in your project.

See the sample in the SDK for reference - msdn.microsoft.com/.../gg695790.aspx

Hi Scott

as you can imagine things are not so obvious

Error 127 The type 'System.Data.Services.IgnorePropertiesAttribute' exists in both 'c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\System.Data.Services.dll' and 'c:\Program Files\Microsoft.Data.Services.5.6.0\lib\net40\Microsoft.Data.Services.dll' Xrm\Xrm.cs

So you seem to have references to the same assembly in two different versions of the .net framework. I suggest you remove both references to System.Data.Services and select only the version from the Assemblies ->Framework tab of the Add Reference dialog..Never browse directly for framework assemblies.

Just set the reference to the "old" System.Data.Services.dll is the only available option.

Currently, when you add a WCF DataService from VS 2012, it add references to the newest Microsoft.Data.Services.dll (fetching via Nuget or you can get directly on www.microsoft.com/.../details.aspx)

This new version of WCF Data service is compatible with OData V3 specs.

Seems that current CRM SDK will not compile when using this new reference.

Anyway, using this approach, you you fall in a poor experience when getting data from large entities, as you don't have control about what is exactly queried by CRM SDK.

I would recommend, create you own model/controller classes, exposing your data via OData WebAPI, querying CRM only exactly what you need.
