Background and motivation

Re: Microsoft.Extensions.Http.Resilience, Microsoft.Extensions.DependencyInjection

So HttpKey is currently not a public API member. When registering resilience handlers on an IHttpClientBuilder using the AddResilienceHandler extension, it creates an HttpResiliencePipelineBuilder by calling AddHttpResiliencePipeline<HttpKey, HttpResponseMessage>.

AFAICT all documentation that deals with "advanced" scenarios, like executing a pipeline using ExecuteAsync with a given ResilienceContext, requires a ResiliencePipelineProvider or ResiliencePipelineRegistry with a key type of string. When using DI to request such a provider, it is not currently possible to reference a type of ResiliencePipelineProvider<HttpKey> because HttpKey is an internal type.

API Proposal

internal readonly record struct HttpKey(string Name, string InstanceName)

should be

public readonly record struct HttpKey(string Name, string InstanceName)

API Usage

ResiliencePipelineProvider<HttpKey> theRegisteredProvider,
