When migrating your BDC app def files, here are some changes I found so far, also I have attached the 2010 BDC Schema (please note this is beta version):
- Root element must be:
- <Model xmlns="http://schemas.microsoft.com/windows/2007/BusinessDataCatalog" Name="AdventureWorksSample">
- A <LobSystems> element must wrap your <LobSystem>
- Your Entities are now partitioned to namespaces (have to add the Namespace attribute)
- Your Entities are versioned now! (have to add the Version attribute)
- More strict second level validation rules attribute IsCollection must be "false"
- SpecificFinder should only return one thing, not sure I like this or not
- A SpecificFinder cannot have the "IDataRecord" Wrapper anymore, you must remove this extra level!
- Forces the creations of a new singleton method with possibly the same parameters (breaking one of my dev rules [don't copy and paste]...hmmm)
- You will have to move your default values to the correct methods (don't copy paste your method definitions unless you want to waste ALOT of time)
- In relationship/association methods, you must specific the IdentifierEntityNamespace of the related entities
- Association is no longer at the rear of the file, it is specified as a subElement of MethodInstance of Method of an Entity
- Namespace attriubute must be on SourceEntity and DestinationEntity
If you really don't want to deal with this, send
