Execute multiple policies

Question

How to execute multiple policies (or combine them into a single one)?

For example I have:

var policy1 = Policy.Handle<DivideByZeroException>().WaitAndRetry(5));

var policy2 = Policy.Handle<StackOverflowException>().RetryForever();

How to apply them to one method at the same time?

As of Polly v5.0, there's a new PolicyWrap class, which let you combine multiple policies.

var policy1 = Policy.Handle<DivideByZeroException>().WaitAndRetry(3, i => TimeSpan.FromSeconds(1));
var policy2 = Policy.Handle<StackOverflowException>().RetryForever();
PolicyWrap policyWrap = Policy.Wrap(policy1, policy2);
policyWrap.Execute(someGreatAction);
