Bind an IConfigurationSection to a complex object without ASP.NET Core

Question

I have a .NET Core console application and want to read the appsettings.json and parse a section as List<Param> (without Dependency Injection or ASP.NET Core).
I already tried How do I bind a multi level configuration object using IConfiguration in a .net Core application? but it seems like .Get<T>() got removed from netcoreapp1.1

IConfigurationSection myListConfigSection = configurationRoot.GetSection("ListA");

List<Param> paramList;

//Get does not exist
//paramList = myListConfigSection.Get<Param>();

string paramListJson = myListConfigSection.Value // is null
// won't work neither because paramListJson is null
paramList = JsonConvert.DeserializeObject<Param>(paramListJson);

appsettings.json:

{
  "ListA": [
    { "ID": "123", "Param": "ABC"},
    { "ID": "123", "Param": "JKS"},
    { "ID": "456", "Param": "DEF"}
  ]
}

Is there an easy way to load the config into the object or do I have to read the config file again and parse it myself with JsonConvert?

Get<T> is defined in package Microsoft.Extensions.Configuration.Binder

Thanks, it did the trick. As much I love it, I sometimes hate that they switched everything to a different nkpg. – Cicatrix

#loveHate Yep,I'm always searching for and finding that "extra" nkpg. – Grecoroman

This doesn't appear to be the same as GetSection as it appears to get the entire config file as an object. – Gillam

You can use it an on IConfiguratoinSection and get just this section as an object – Vshaped
