AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Updates the parameter values for stack instances for the specified accounts, within the specified Amazon Web Services Regions. A stack instance refers to a stack in a specific account and Region.

You can only update stack instances in Amazon Web Services Regions and accounts where they already exist; to create additional stack instances, use CreateStackInstances.

During stack set updates, any parameters overridden for a stack instance aren't updated, but retain their overridden value.

You can only update the parameter values that are specified in the stack set; to add or delete a parameter itself, use UpdateStackSet to update the stack set template. If you add a parameter to a template, before you can override the parameter value specified in the stack set you must first use UpdateStackSet to update all stack instances with the updated template and parameter value specified in the stack set. Once a stack instance has been updated with the new parameter, you can then override the parameter value using UpdateStackInstances.

Note:

For .NET Core this operation is only available in asynchronous form. Please refer to UpdateStackInstancesAsync.
