Hello,

We're now migrating an existing application with a new version of Oracle.DataAcess 4.122.19.1 with our LLBLGen Pro 5.3.1 I've added the new oracle dll in my project and it fails with the following error message : at SD.LLBLGen.Pro.ORMSupportClasses.DbProviderFactoryInfo.get_FactoryToUse() at SD.LLBLGen.Pro.ORMSupportClasses.DbProviderFactoryInfo.InitializeEnumTypeCache() at SD.LLBLGen.Pro.DQE.Oracle.OracleSpecificCreator.SetDbProviderFactoryParameterData(List`1 dbProviderFactoryInvariantNamesWithEnumTypeNames, String dbProviderSpecificEnumTypePropertyName) at SD.LLBLGen.Pro.DQE.Oracle.DynamicQueryEngine..cctor()

Is there a compatibility issue between those versions ?

No, but you likely have to do some extra work to get the DbProviderFactory registered. Please see these steps: https://www.llblgen.com/Documentation/5.8/Designer/Databases/oracleodpnet.htm#registering-odp.net-in-the-gac-and-machine.config
