    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.

4. Gets a list of open cases for the current day.
5. Creates an attachment set with a generated file.
6. Adds a communication with the attachment to the support case.
7. Lists the communications of the support case.
8. Describes the attachment set included with the communication.
9. Resolves the support case.
10. Gets a list of resolved cases for the current day.
