I'm doing a bit of a technical investigation into the ExecuteTransactionRequest. It's not something I've ever used before so I knocked up a very quick experiment just to see how it works. However, when sending off the request the OrganizationService is throwing back a FaultException (below). What I believe is happening is that my version of CRM doesn't support that OrganizationRequest. Although I'm pretty sure I have the right assemblies and version.
Can anyone please shed some light on what I'm missing?
CRM Deployment Version: 7.0.1.129
Organization Version: 7.0.2.53
Microsoft.Xrm Assembly Version: 7.0.0.0 (Also happened with 8.0.0.0)
An unhandled exception of type 'System.ServiceModel.FaultException' occurred in Microsoft.Xrm.Sdk.dll
