Provides sample implementations of the Polly library. The intent of this project is to help newcomers kick-start their use of Polly within their own projects.
- The demos show different flavors of retry; then retry combined with Circuit-Breaker.
- The demos run against an example 'faulting server' (also within the solution). To simulate failure, the 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 each demo, what it achieves (in relation to the dummy 'faulting server'), what it doesn't yet achieve. - Explore the demos in sequence for best understanding: each solves a problem which the previous didn't.
- To start the dummy server, start
PollyTestApp. - Be sure the port number for the dummy server in
PollyTestClient\Configuration.csmatches the port on whichPollyTestAppstarts on your machine. - To run a demo, uncomment the demo you wish to run in
PollyTestClient\program.cs. Then startPollyTestClient.
- Any questions about the operation of the demos, ask on this repo; any questions about Polly, ask at Polly.
