In program.cs I can do
services.Configure<Blah>(configuration.GetSection("foo"));
But when I create an extension method for IServiceCollection there is no Configure method to use
namespace Microsoft.Extensions.DependencyInjection;
public static class ServiceExtensions
{
public static IServiceCollection AddMyServices(this IServiceCollection services, IConfiguration config)
{
// I am getting an error in this line 'IServiceCollection does not contain a definition for Configure'
services.Configure<Blah>(config.GetSection("foo"));
return services;
}
}
What is the reason?
You need to add https://nuget.org/packages/Microsoft.Extensions.Options package in the project where your extension method is. In the WebApi project, this package is added behind the scenes.
