I am in need for a working 32bit OCI mode - is it possible to get a private build when this is fixed?

We have fixed the bug with MethodAccessException in .NET Standard 1.3 compatible assemblies when linking them to a project, targeting Full .NET Framework. We are planning to release a new build at the end of the next week. We will post here when the corresponding build of dotConnect for Oracle is available for download.

Hello,

I am using .NET 4.6.2 (OCI) and your latest NuGet Library and am getting the same error?

Attempt by security transparent method 'Devart.Data.Oracle.Linq.Provider.OracleDataProvider.CreateConnection()' to access security critical method 'Devart.Data.Oracle.OracleConnection..ctor()' failed.

Assembly 'Devart.Data.Oracle.Linq, Version=4.8.1398.0, Culture=neutral, PublicKeyToken=09af7300eec23701' is marked with the AllowPartiallyTrustedCallersAttribute, and uses the level 2 security transparency model. Level 2 transparency causes all methods in AllowPartiallyTrustedCallers assemblies to become security transparent by default, which may be the cause of this exception.
