I am in the process of migrating a web api from SnapDevelop R1 to R2.  We have about 50 datawindows that were exported to the api using the C# Model Generator.  The exported srd's and classes for these were in a 'DataWindows' folder along with the companion config file.  Per the migration instructions, I removed these from the project.  I then tried to use the Datawindow Converter but it is not working.  We are getting the following error regardless of which datawindow I try to convert:

ORA-00904: "C"."IDENTITY_COLUMN": invalid identifier

Our dw's are a mix of external datawindows and those with SELECT statements.  It's odd to me that an external datawindow would get this error.  In addition, if I try to preview the model in the Datawindow Converter window I get the attached error.

Before attempting to convert any of the datawindows, I was able to setup a connection to the Oracle (v12) database we use.  I also swapped out all of the old versions of the PB and SnapDevelop nuget packages with their newer counterparts.  Unfortunately, I can't do a successful build in SnapDevelop because it can't find the namespace for the dw models that no longer exist.

Did I miss a configuration setting or a migration step?  Any suggestions on how to resolve this issue?

Thanks, Tom
