We're converting to OpenRiaServices. We have some usage of the SubmittedChangesEventArgs class and I found it in the OpenRiaServices.Controls.DomainServices.dll.
But, I can't find a NuGet package that provides that assembly.
Is there one?
That is OpenRiaServices.Silverlight.DomainDataSource. If you are not using the DomainDataSource then you shouldn't be using SubmittedChangesEventArgs.
