Entity Framework Core multiple connection strings on same DBContext?

Question

I have an Asp.Net Core app with Entity Framework Core that I initialize as follows:

services.AddDbContext(options => 
                 


        

Answer 1

You'll need two DbContexts.

public class BloggingContext : DbContext
{
    public DbSet Blogs { get; set; }
    public DbSet Posts { get; set; }
}

public class MyBloggingContext : BloggingContext
{

}

public class MyBackupBloggingContext : BloggingContext
{

}

And you can register them like this:

public void ConfigureServices(IServiceCollection services)
{
    services.AddDbContext(options =>
        options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

    services.AddDbContext(options =>
        options.UseSqlServer(Configuration.GetConnectionString("BackupConnection")));

}
