Use env.EnvironmentName in GetConnectionString

[lukpep]

instead of

var builder = new Microsoft.Extensions.Configuration.ConfigurationBuilder()
                .SetBasePath(Directory.GetCurrentDirectory())
                .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);

use maybe:

var builder = new Microsoft.Extensions.Configuration.ConfigurationBuilder()
                .SetBasePath(Directory.GetCurrentDirectory())
               .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)

so its possible to specyfi different connection string in local development and on production
