    Before running this .NET code example, set up your development environment, including your credentials.
    To use the AWS Support API, you must have one of the following AWS Support plans: Business, Enterprise On-Ramp, or Enterprise.

    This .NET example performs the following tasks:
    1.  Get and display services. Select a service from the list.
    2.  Select a category from the selected service.
    3.  Get and display severity levels and select a severity level from the list.
    4.  Create a support case using the selected service, category, and severity level.
    5.  Get and display a list of open support cases for the current day.
    6.  Create an attachment set with a sample text file to add to the case.
    7.  Add a communication with the attachment to the support case.
    8.  List the communications of the support case.
    9.  Describe the attachment set.
    10. Resolve the support case.
    11. Get a list of resolved cases for the current day.
