OpenTelemetry Support for .NET Aspire

[NapalmCodes]

Is your feature request related to a problem? Please describe. It would be useful when using a WireMock in .NET Aspire for the OTEL data to be populated as expected in the OTEL dashboard. This facilitates troubleshooting and the development process.

Describe the solution you'd like I would expect to see appropriate headers like traceparent respected and traces, logs, metrics to be pushed to the OTEL collector behind the dashboard.

Describe alternatives you've considered N/A

Is your feature request supported by WireMock (java version)? Please provide details. Based on a quick search it appears an extension might be under development: https://github.com/wiremock/wiremock-otel-extension

Additional context Add any other context or screenshots about the feature request here.

@NapalmCodes Looks like a good suggestion, however can you point me to some documents which describe how to build this?

I think it would be a matter of installing the extension in the WireMock container and pointing it at the OTEL connection. The Aspire IResourceWithEnvironment interface provides access to all the OTEL_* env vars that can be utilized to send the telemetry to. You can see an example ContainerResource here from my KrakenD component. I then just use those env vars to tell my gateway where to send the logs, metrics and traces to (i.e.: the OTEL collector the Aspire Dashboard runs). Does that help @StefH ?

A gap for me is how to install the extension. I haven't worked with the Java wiremock solution directly.
