Five debugger-related tests added in #121054 fail in NativeAOT outerloop runs where DebuggerDisplay/DebuggerTypeProxy attributes are unsupported.

Changes

Converted five test methods in ActivityTests.cs from [Fact] to [ConditionalFact(typeof(PlatformDetection), nameof(PlatformDetection.IsDebuggerTypeProxyAttributeSupported))]:

  • TestActivityDebuggerDisplay
  • TestActivityDebuggerProxy
  • TestActivityContextDebuggerDisplay
  • TestActivityLinkDebuggerDisplay
  • TestActivityEventDebuggerDisplay

This matches the pattern used for similar debugger tests throughout the codebase (System.Linq, System.Collections.Concurrent, System.Collections.Immutable, etc.) and ensures tests are skipped on platforms where PlatformDetection.IsDebuggerTypeProxyAttributeSupported returns false.

Original prompt

Convert the tests added in #121054 from [Fact] to [ConditionalFact(typeof(PlatformDetection), nameof(PlatformDetection.IsDebuggerTypeProxyAttributeSupported))], matching the pattern used for similar tests across the repo. This will avoid failures in NativeAOT outerloop runs, where DebuggerDisplay/DebuggerTypeProxy support is not available. The affected tests are: TestActivityDebuggerDisplay, TestActivityDebuggerProxy, TestActivityContextDebuggerDisplay, TestActivityLinkDebuggerDisplay, and TestActivityEventDebuggerDisplay in src/libraries/System.Diagnostics.DiagnosticSource/tests/ActivityTests.cs.

Pull Request Overview

This PR updates debugger-related tests in ActivityTests.cs to use conditional execution based on platform support for debugger type proxy attributes. These tests were previously marked with [Fact] and are now marked with [ConditionalFact] to ensure they only run on platforms where debugger attributes are supported (i.e., not on NativeAOT).

Key Changes

  • Converted five test methods from [Fact] to [ConditionalFact] with platform detection
  • All changes target tests that validate debugger display and debugger proxy functionality
  • Pattern is consistent with similar debugger tests across other libraries in the codebase
