i'am working with a OA Version 2010.1.623.5.
The reference to Telerik.OpenAccess.40.Extensions i removed and added a new telerik domain
service (OpenAccessDomainService.tt) with the data wizard. strange that the dialog does not show avaiable entities.
but ok now i have an empty datacontext.
the error message after compilation is following:
C:\Program Files\MSBuild\Microsoft\Silverlight\v4.0\Microsoft.Ria.Client.targets(303,5): error : Exception has been thrown by the target of an invocation.
This is the CreateRiaClientFilesTask wich throws the error.
