 The <xref:Microsoft.Extensions.DependencyInjection.PollyHttpClientBuilderExtensions.AddTransientHttpErrorPolicy(Microsoft.Extensions.DependencyInjection.IHttpClientBuilder,System.Func{Polly.PolicyBuilder{System.Net.Http.HttpResponseMessage},Polly.IAsyncPolicy{System.Net.Http.HttpResponseMessage}})> method is an opinionated convenience method that supports the application of a policy for requests that fail due to a connection failure or server error (5XX HTTP status code). This kind of method supports only reactive policies such as Retry, Circuit-Breaker or Fallback. This method is only provided for convenience; we recommend creating your own policies as needed if this does not meet your requirements.
