Johannes Häggqvist	8e69f36f04	Add WireMockHealthCheck in WireMock.Net.Aspire (#1375 ) * Add WireMockHealthCheck For use with Aspire, to make WaitFor(wiremock) more useful. Calls /__admin/health and checks the result, as well as checks if mappings using AdminApiMappingBuilder has been submitted to the server. This created a catch-22 problem where the mappings were not submitted until the health check was healthy, but the health check was not healthy until the mappings were submitted. To avoid this, the WireMockServerLifecycleHook class has been slightly re-arranged, and is now using the AfterEndpointsAllocatedAsync callback rather than the AfterResourcesCreatedAsync callback. Within which a separate Task is created that waits until the server is ready and submits the mappings. * Move WireMockMappingState to its own file * Dispose the cancellation tokens in WireMockServerLifecycleHook	2025-11-17 20:14:42 +01:00
