I am getting the following error when trying to connect to Oracle with .NET Core using Entity Framework Core

Method 'PopulateDebugInfo' in type 'Oracle.EntityFrameworkCore.Infrastructure.Internal.OracleOptionsExtension' from assembly 'Oracle.EntityFrameworkCore, Version=2.0.19.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.

Microsoft.EntityFrameworkCore v 2.2.4

Microsoft.EntityFrameworkCore.Tools v 2.2.4

Microsoft.NETCore.App v 2.2.0

Oracle.EntityFrameworkCore v.2.19.0-beta4

Oracle.ManagedDataAccess.Core v.2.19.3

Error occurs when executing UseOracle as below:

        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)

        {

            if (!optionsBuilder.IsConfigured)

            {

                var connectionString = "(description = (address = (protocol = tcp)(host = {host name})(port = {port number))(connect_data =                     (service_name = {name})))";

                optionsBuilder.UseOracle(connectionString);

            }

        }

I tried a simple console app using only the assemblies and the versions you have listed. I was able to successfully the app without error.

Can you check whether your project has a .NET Core 3 assembly among its other dependencies? Typically, I've seen this error occur when a .NET Core 3 library sneaks in.

Thank you, I built a new project and was able to connect successfully.  There must have been a lingering reference to .NET Core 3 beta.
