[BUG] Testing with "Testing Platform Protocol" option hangs when debugging

[erwinkramer]

Describe the Issue

Testing with the (experimental) Testing Platform Protocol option (dotnet.testWindow.useTestingPlatformProtocol) will not start when debugging.

I'm using TUnit.

I can confirm it does work well with the similar option enabled on Microsoft Visual Studio Community 2022 (64-bit) - Preview, so it seems an isolated issue to the C# Dev Kit extension.

Reference to the issue on the TUnit project: thomhurst/TUnit#1246

Steps To Reproduce

1. Clone this repo: https://github.com/erwinkramer/bank-api?tab=readme-ov-file#bank-api
2. Observe the tests: https://github.com/erwinkramer/bank-api/blob/main/BankApi.Tests/Program.cs
3. Run the tests in debug mode, so click: Debug Test.

Expected Behavior

1. Should start and debug the tests
2. Should be able to cancel them

Environment Information

• OS: WIndows 11
• VSCode version: 1.95.3
• Extension version:
  • C# Dev Kit: v1.14.2 (pre-release) and v1.13.9
  • C#: v2.55.29
