Amazon STS examples using Amazon SDK for .NET

The following code examples show you how to perform actions and implement common scenarios by using the Amazon SDK for .NET with Amazon STS.

Actions are code excerpts that show you how to call individual service functions.

Scenarios are code examples that show you how to accomplish a specific task by calling multiple functions within the same service.

Each example includes a link to GitHub, where you can find instructions on how to set up and run the code in context.
