Custom Resource CloudFront Invalidation In C#

[smguggen]

Describe the feature

This example uses an AwsCustomResource to produce an invalidation on an Amazon CloudFront Distribution. A CloudFront Invalidation wipes away the cached content so that new changes in the distribution's origin can be seen immediately.

The AwsCustomResource CDK construct is an L3 Construct that can be used to create an AWS CloudFormation Custom Resource without having to directly create the AWS Lambda Function to support it.

An AwsCustomResource is appropriate to use when you have exactly one AWS SDK call to make per stack task: onCreate, onUpdate, and onDelete.

Use Case

When a stack with a CloudFront Distribution and an S3 Origin wants to clear the cache every time changes are deployed to the origin.

Proposed Solution

The package is an example of this being done, but it also contains an abstracted helper class that can be dropped in to existing stacks and used for any use case.
