One Answer:

Hello Anton.

Technically, there is nothing wrong with this behavior. You use same model in both cases. In the first case DataObjects.Net ignore all recycled types and doesn't create tables. In the second case, DataObjects.Net tries to create RenameTypeHint for each type which marked as recycled. But it does not find ConsoleApplication1.Recycled in old model, because ConsoleApplication1.Recycled wasn't created in database in the first case.

RecycledAttribute helps to rename type without manual creation of RenameTypeHint on upgrade from one model to another. If old name of type was not defined in attribute, DataObjects.Net tries to remove specified suffix from namespace of new type and defines name of old type by this value.

But logically, it is incorrect behavior. Dataobjects.Net should not create hints automatically or must throw exception if it does not find type with old name in old model.

Thank you for your report. We will fix it in next version of DataObjects.Net.

Small, but important notice:

1 Throw exception doesn't resolve our issue.

For example, we have initial scheme, mark some types with [Recycled], do 'Perform', change more models (still have old [Recycled] attributes), do 'Perform' (on this step we already have scheme without recycled types in DB, but, I think, nothing wrong with it)

Don't create hints will be much more better.

2 What about resolve time? Next version - is hotfix, or something else? Worried about that, becouse other similar bug hanging from February (

Hi Anton. Both bugs have already fixed. We plan to release next version very soon.
