Provides sample implementations using the Polly library. The intent of this project is to help newcomers kick-start their use of Polly within their own projects.

• The demos run against an example 'faulting server' (also within the solution). To simulate failure, this dummy server rejects more than 3 calls from the same IP in any five-second period.
• Be sure to read the <summary/> at the top of each demo: this explains the intent of that demo, and what it achieves (in relation to the dummy 'faulting server').
• Sometimes the <summary/> also highlights what this demo doesn't achieve - often picked up in the following demo. Explore the demos in sequence, for best understanding.

• Demo 00 shows behaviour calling the faulting server every half-second, with no Polly policies protecting the call.
• Demos 01-04 show various flavors of Polly retry.
• Demos 05-06 show retry combined with Circuit-Breaker.
• Demo 07 shows the Polly v5.0 PolicyWrap for combining Retry and CircuitBreaker.
• Demo 08 adds Polly v5.0 Fallback, making the call protected (in a PolicyWrap) by a Fallback, Retry, Circuitbreaker.
• Demo 09 shows the Polly v5.0 Timeout policy for an overall call timeout, in combination with Fallback and WaitAndRetry.

• To start the dummy server, start PollyTestApp.
• Be sure the port number for the dummy server in PollyTestClient\Configuration.cs matches the port on which PollyTestApp has started on your machine (in the previous step).
• To run a demo, uncomment the demo you wish to run in PollyTestClient\program.cs. Then start PollyTestClient.

• Any questions about the operation of the demos, ask on this repo; any questions about Polly, ask at Polly.
