The .NET Aspire is a cloud-ready stack for building observable and production-ready distributed applications, including features like a developer dashboard, tooling and orchestration, and components that facilitate integration with prominent services and platforms. It aims to solve challenges such as complexity, getting started, choices, and paved paths in cloud-native application development. The .NET Aspire includes a curated suite of NuGet packages, project templates, and tooling experiences for Visual Studio and the dotnet CLI. To send telemetry to an OpenTelemetry backend like New Relic, users can configure OpenTelemetry correctly by leveraging SDKs and environment variables, providing necessary configuration such as the OTLP endpoint, headers, and service name, and then starting the Aspire application with the correct command.
