Versions backward compatibility in development environment

[Dominik]

Hi,

We have upgrade our Devart dotConnect for Oracle version from 5.70.190 to 8.1.45 regarding a problem with framework .NET 4.5.

Now we have installed the new Devart product in our development environment, but we also have old versions of our product projects referencing v5.70 libraries. So in this case, when we run an older project we get this error at execution time:

MissingMethodException - Method not found: 'Void Devart.Data.Oracle.Entity.OracleEntityProviderServices.set_TypedNulls(Boolean)'.

Is there any way to solve this problem?

Thanks in advance,

Dominik.

Please refer to http://forums.devart.com/viewtopic.php?t=20149. Have you removed the policy.*.Devart.* files from both GAC 2.0 (\Windows\assembly\) and GAC 4.0 (\Windows\Microsoft.NET\assembly\)?

If this doesn't help, run your project in the debug mode, navigate to Debug > Windows > Modules and make sure that all Devart.* assemblies, which are loaded in the process of the application, correspond to the same version of dotConnect for Oracle provider.
