In the 5.0 release there were some important name changes in the product. Particularly,
assemblies, namespaces, invariant name, and some types were changed as follows:
"CoreLab.Data" became "Devart.Data";
"CoreLab.Oracle" became "Devart.Data.Oracle";
"OracleDirectFactory" became "OracleProviderFactory";
Invariant name became "Devart.Data.Oracle";
Your projects must be updated to be compatible with dotConnect for Oracle 5.0. Here
is the list of files you should update:
*.csproj, *.vbproj - references to assemblies
*.cs, *.vb - namespaces
*.licx - namespaces and assembly names
Web.config - assembly names and web provider types
This is done automatically when you invoke the Upgrade wizard from Visual Studio
menu: Tools | Oracle | Upgrade Wizard.
Devart data providers use a common assembly (Devart.Data.dll), so it is necessary
to install compatible providers versions. We release our ADO.NET data providers
in a single pack, thus releases from the same date should be compatible. Also, Devart
data providers should warn you before installation if an incompatible version of
Devart.Data.dll was detected.
You should put the Devart.Data, Devart.Data.Oracle, and Devart.Data.Oracle.Entity
assemblies in the Bin folder of your application (or place these assemblies in Global
Assembly Cache). Make sure that your application is licensed correctly (take a look
at the Licensing
article for more information).

in the further Oracle versions.
