Setting TestingPlatformDotnetTestSupport makes tests non discoverable

[OnurGumus]

Describe the bug

There is a new post from microsoft dev blogs

They introduced TestingPlatformDotnetTestSupport switch in the project file. Once you set that true, tests aren't discoverable by ionide.

     <TestingPlatformDotnetTestSupport>true</TestingPlatformDotnetTestSupport>

To be fair I am not entirely sure what this new switch brings to table.

Steps to reproduce

Create any test project then true

Ionide will complain no tests are discoverable.

Expected behaviour

Ionide should discover the tests

Machine info

• MacOS 15
• .NET SDK version:9
• Ionide version: 7.25

I tested this, and found some significant problems.

First, Microsoft.Testing.Platform doesn't respect <GenerateProgramFile>false</GenerateProgramFile>.

This means that using versions of YoloDev.Expecto.TestSdk which depend on Microsoft.Testing.Platform can't define their own main method (and thus can't be run as a normal expecto project). This is true even if EnableExpectoTestingPlatformIntegration and TestingPlatformDotnetTestSupport aren't enabled.

Second, Microsoft.Testing.Platform doesn't respect dotnet test flags like --logger and --list-tests.
This makes it incompatible with the way the Ionide test explorer currently works, which relies on --logger to discover tests and to report test results.

I confirmed that the --logger and --list-tests support is also missing from XUnit, not just YoloDev/Expecto.

In short, Microsoft.Testing.Platform won't work with Ionide short of rewriting test and result discovery or Microsoft.Testing.Platform better respecting dotnet test parameters.
