How to make Depency Injection with AddDbContext in .NET Core

[eddorneles]

I've checked the "source_files" sample but it was to simple for my understanding...

The MySQL provider and Npgsql providers suggests create the database connection inside the Context class, something like:

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) 
=> optionsBuilder.UseNpgsql("Host=my_host;Database=my_db;Username=my_user;Password=my_pw");

And in the ConfigureService method of the Startup class, some code like this:

public void ConfigureServices(IServiceCollection services)
{
    services.AddDbContext<OracleContext>().BuildServiceProvider();
}

So, I'd like to know if is possible to make the dependency injection like that, does exist some method like the "UseNpgsql()" in Oracle.ManagedDataAccess.Core? In fact, does this driver support Entity Framework Core Object Mapping? Or is it only for database access purposes with native queries?

Thanks in advance!

Oracle Entity Framework Core will support dependency injection, but it is not yet available. We hope to provide the public beta soon. You can see a code sample here:

Hi, I downloaded the beta provider from nuget and took a look at the samples on Github, but the AspNet Core sample is creating the DbContext manually, which is not a true and practical AspNetCore usage.

Is there any dependency injection support by now?
