Issue upgrading to Oracle.ManagedDataAccess.Core 2.19.100

Hi, I upgraded the Oracle.ManagedDataAccess.Core package from 2.19.70 to 2.19.100 in my AspNet Core application (.NET Core 3.1) and I encounter this issue:

Error Message: System.TypeInitializationException : The type initializer for ‘OracleInternal.Network.AddressResolution’ threw an exception. ---- System.IO.FileNotFoundException : Could not load file or assembly ‘System.DirectoryServices.Protocols, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’.

From what I’ve seen on Nuget it doesn’t have System.DirectoryServices.Protocols as a dependency, however, when inspecting the DLL, it looks like the package has references to System.DirectoryServices.Protocols:

@hiezust It’s an idea, though I don’t believe any other ADO.NET data provider does this, not even Microsoft’s own providers.

How Microsoft decides to break up the .NET Runtime into separate packages does not have hard and fast rules. It could change from release to release based on what MS views as the most commonly used packages.

I’d argue this issue was not properly resolved.
