hi!

i would like to know how to deal with the fact that i have a project that use dotConnect v5.70.190.0 and another one that is on v5.70.170.0 on the same machine.

Since that i can only have ONE version of dotConnect installed for Visual Studio, how can i play with 2 differents version of dotConnect?

Here are two sides of using dotConnect for Oracle:

deployment (there is no need to build/re-build assemblies in the deployment environment)
You can have as many versions of dotConnect for Oracle on your workstation as you want. And each of your applications will use its particular version of our provider. To use this scenario, you should set the Specific Version property of the references to our assemblies to True. In this case you can either copy our assemblies to your deployment environment or run our installation in the "Minimal" mode. Be aware that every dotConnect for Oracle installation package places the policy.*.Devart.* files to GAC. If you use several versions of our provider, you should remove these policy files from your GAC.
development (building assemblies)
The dotConnect for Oracle license resource is built into your assembly when you use our product (.NET component licensing). This resource is version dependent. The license resource of the version, assemblies of which are referenced in the project, will be embedded into the project (remove the policy.*.Devart.* files from GAC before). But there are design time problems in Visual Studio if you install serveral versions of dotConnect for Oracle.

EDIT: correction of the development section

so whats the solution if i need to use Visual Studio with dotConnect v6 on one project and also use Visual Studio with dotConnect v5?

I understand that i can deploy the version that i want in the bin folder of the project, for example. But how to play with EntityFramework with 2 differents version of dotConnect?

Solution for developing applications with different versions of dotConnect for Oracle on the same machine is uninstall/install-ing provider every time when switching between versions.

Note.
If you are downgrading (higher version -> lower version), and the higher version of the provider for some reason doesn't remove its policy.*.Devart.* files from the GAC, you should delete these publisher policy files manually.

geez.. this solution is not funny at all !

can you tell me if theres any breaking changes between versions of dotConnect? i mean, if i need to do a maintenance on an older project with older dotConnect references, is there any problems to use the new one? i know i need to make some tests but in general, using v5 to v6 is an easy migration?

Please refer to the dotConnect for Oracle revision history.
You can use the Tools > Oracle > Upgrade Wizard menu to upgrade all references in your project to the newer version of the Devart.* assemblies.
If you encounter any difficulties, please contact us.
