I have the following code:

        using (OracleConnection connection = new OracleConnection(_connectionString.Value.Mix_DB))
        {
            var fish = connection.Query<dynamic>("SELECT Username, Password FROM Orderform_Users");
        }

When I run the code, I get the following exception:

System.TypeLoadException: 'Could not load type 'System.Security.Principal.WindowsImpersonationContext' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.'

I have downloaded the latest version of ODP.NET (Oracle Data Provider for .NET Core 12.2 Beta 3)

Anyone who can guide me into the right direction with this problem?

  • The ODP.Net provider for .net core is still in beta, are you using the correct version? (oracle.com/technetwork/topics/dotnet/downloads/…) Commented Aug 14, 2018 at 6:44
