114 | Sanction handling:
115 |
116 | If the amount of the fine is to be determined by the prosecutor, you will receive a notice
117 | to appear in court shortly.
118 |
119 | Otherwise, you must pay the sanctioned fine within 8 weeks after the date of this
120 | email. If you fail to pay within 8 weeks, you will receive a first reminder email and the
121 | fine will be increased to 1.5x the original fine amount. If you fail to pay within 8 weeks
122 | after the first reminder, you will receive a second and last reminder email and the fine
123 | will be increased to 3x the original fine amount. If you fail to pay within 8 weeks
124 | after the second reminder, the case is turned over to the prosecutor and you will receive a
125 | notice to appear in court.

2 |
3 | The Dapr workshop is a workshop that teaches you how to apply [Dapr](https://dapr.io) to a microservices application. This repository contains the source-code that forms the starting point of the C# (.NET) version of the workshop. With each workshop assignment you will expand the application with a Dapr building block.

5 | See the [Dapr workshop repository](https://github.com/edwinvw/dapr-workshop) for more information and instructions on how to get started.
