How to configure DbContext with ODP.NET Core

c0036513-d01d-46af-8a69-d47e16c6c3ceOct 25 2018 — edited Apr 3 2019

It seems that Oracle released the ODP.NET Core version (see https://www.nuget.org/packages/Oracle.ManagedDataAccess.Core/). If this is accurate, please share how to set it up by using the DbContextOptions (or in any other "injectable" way, not by manually instantiating the connection and command objects (as in https://www.oracle.com/webfolder/technetwork/tutorials/obe/db/dotnet/ODPNET_Core_get_started/index.html).

I am not able to configure the DbContext from the Startup, Configuration method as described in StackOverflow (https://stackoverflow.com/questions/52972234/options-useoracle-not-available-in-ef-core ):

services.AddDbContext<BloggingContext>(options => options.UseOracle(ora_conn)); 

"UseOracle" is not a method that is available.

I have included the following namespaces:

using Oracle.ManagedDataAccess.Client;

using Microsoft.EntityFrameworkCore;

Even when I try dotnet ef dbcontext scaffold (with and without the option -c HiddenContext), it fails with the error "Unable to find expected assembly attribute named DesignTimeProviderServicesAttribute in provider assembly Oracle.ManagedDataAccess. This attribute is required to identify the class which acts as the design-time service provider factory."

dotnet ef dbcontext scaffold "DATA SOURCE=hidden;PASSWORD=hidden;PERSIST SECURITY INFO=True;USER ID=hidden;Connection Timeout=60;min pool size=0;connection lifetime=1800;" Oracle.ManagedDataAccess --output-dir Tables --schema hidden -t table1 -t table2 -t table3 -t table4 -t table 5 -v

What am I missing? Can anybody point me to any suggestions out there?

Please, please, help...
