 Bulk support in the .NET SDK works by leveraging the [Task Parallel Library](https://docs.microsoft.com/dotnet/standard/parallel-programming/task-parallel-library-tpl) and grouping operations that occur concurrently. 
 
-There is no single method that will take your list of documents or operations as an input parameter, but rather, you need to create a Task for each operation you want to execute in bulk.
