The C# project that I'm working on uses Polly (v8.3) for resiliency. The code looks very much similar to the sample found in the Github documentation :
ResiliencePipeline pipeline = new ResiliencePipelineBuilder() .AddRetry(new RetryStrategyOptions{/*omitted*/}) .Build();and subsequently
pipeline.Execute(() => SomeVoidMethodThatMayFail());The retry options have been omitted here, it boils down to that Polly will retry 5 times and on every failed attempt an entry is written to a log. As can be deduced from the use of a non-generic RetryStrategyOptions, the code that may throw an exception has a return type of void.
The last thing that I need to implement, is a 'finally'-block, e.g. send an email if the retries have been exhausted. I thought of using a fallback, but there is no non-generic FallbackStrategyOptions. What would be the appropriate Polly-way to execute codeafter the last retry has failed? Of course, I could change my method to return e.g. bool instead of void, but that seems like a work around
