Adding a scoring profile with the .NET client

I can't find how to use the .NET Client for Azure search to add a scoring profile. Yes, I know there's a doc to do it using the REST API Thanks.

The scoring profiles have to be created at the same time as the index:

private async Task CreateIndexAsync<T>(string index) where T : class
{
    var definition = new Index()
    {
       Name = index,
       Fields = FieldBuilder.BuildForType<T>(),
       ScoringProfiles = new List<ScoringProfile>
       {
           //your scoring profiles here
       }
   };

   if (!_adminServiceClient.Indexes.Exists(index))
   {
       await _adminServiceClient.Indexes.CreateAsync(definition);
   }

 }
