Couple of things to check before stable release:

1. https://github.com/open-telemetry/opentelemetry-dotnet-contrib/blob/0a7b14d2a7e319cc43ee321a2f705ff85b84c050/src/OpenTelemetry.Instrumentation.Runtime/README.md#troubleshooting dont see any actual logging? is this accurate?

2. opentelemetry-dotnet-contrib/src/OpenTelemetry.Instrumentation.Runtime/RuntimeInstrumentOptions.cs

   Line 22 in 0a7b14d

   public class RuntimeInstrumentOptions

   - The name sounds incorrect to me.. RuntimeInstrumentationOptions would be more apt.
3. There is not much public API, but need to make sure no breaking changes once 1.0.0 is shipped. Consider using public api analyzer before releasing stable version of any component.
