Pull request overview
This PR simplifies the ASP.NET Core instrumentation benchmark suite by switching to ASP.NET Core TestServer (to avoid real network calls), consolidating the old duplicated benchmark classes into a single benchmark type, and adding a gRPC benchmark path.
Changes:
- Replaced the old HTTP-only benchmark classes with a single
AspNetCoreBenchmarksbenchmark usingTestServer. - Added gRPC benchmarking support (proto + in-process gRPC service/client).
- Added
Microsoft.AspNetCore.TestHostto central package versions and updated benchmark project dependencies accordingly.
