we have an ASP.Net 4.5.2 application using the latest Oracle.ManagedDataAccess.dll from nuget with Entity Framework 5.

File version: 4.121.1.0

Product version: 4.121.1.20131211

When deployed to production environment (Windows Server 2008 r2 x64) all works fine, until we need distributed transactions.

Oracle documentation states that we need to provide Oracle.ManagedDataAccessDTC.dll (of same version, for specific platform x64) in order to get distributed transactions working.
