After updating "dotConnect for Oracle" from version 9.x to 10.0 I'm getting an exception at runtime:

Exception ocurs at: System.Data.EntityCommandCompilationException: 'An error occurred while preparing the command definition. See the inner exception for details.'

Inner Exception message:
"Inheritance security rules violated by type: 'Devart.Common.Entity.ei'. Derived types must either match the security accessibility of the base type or be less accessible."

Source: "Devart.Data.Oracle.Entity.EF4"

Stacktrace: at Devart.Common.Entity.ew.c()

at Devart.Data.Oracle.Entity.OracleEntityProviderServices.CreateDbCommandDefinition(DbProviderManifest baseProviderManifest, DbCommandTree commandTree)

at System.Data.EntityClient.EntityCommandDefinition..ctor(DbProviderFactory storeProviderFactory, DbCommandTree commandTree)

Tried to remove and add references a dozen times, and I'm still stuck, what should I do to fix this?

Thank you.

You are working with Entity Framework 4 and .NET Framework 4.8, aren't you?

We have reproduced the issue and are investigating it. We will notify you about the result.

I'm using EF4 and .Net Framework 4.7.2..

Thank you.
