[http-server-csharp]: Tests for standard ARM template coverage

[markcowl]

• Create end-to-end tests for samples using standard arm templates / azure-http-specs
  • Should start with ProxyResource sample
  • Add in tests for standard scalar, union, enum, record, and array types
  • Validate no issues with ARM library type parsing, including anonymous instantiation of templates
• Validate azure-http-specs scenarios and add additional scenarios as needed
• Validate correct generation, compilation, scaffolding, and simple end-to-end tests

🎯 Issue Triage

This requests end-to-end coverage for standard ARM templates in the C# HTTP server emitter, beginning with ProxyResource and covering common TypeSpec data shapes. The tests should validate generation, scaffolding, compilation, ARM library type parsing, and basic runtime behavior.
Category: Feature Request
Area: emitter:service:csharp

🔍 Analysis

The affected component is @typespec/http-server-csharp and its sample/end-to-end test infrastructure. The proposed matrix includes scalar, union, enum, record, and array types, with particular attention to anonymous ARM template instantiations. No strong duplicate was found; similarly worded issues cover client generation, isolated server-emitter defects, or broader HTTP-spec coverage rather than this ARM sample test suite.

📝 Suggested next steps

• Add the ProxyResource end-to-end fixture and assertions.
• Expand coverage across the listed standard data shapes and anonymous template instantiation.
• Verify generated projects scaffold, compile, and pass basic end-to-end behavior checks.
