CanValidateTypeWithParsableProperties test failure

[marcominerva]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

I have cloned the repository and ran the test suite from the src/Validation folder using:

build.cmd -test

One test is failing:

Microsoft.Extensions.Validation.GeneratorTests.ValidationsGeneratorTests.CanValidateTypeWithParsableProperties
Assert.Collection() Failure: Item comparison failure

Expected Behavior

The test should pass.

Steps To Reproduce

Launch the test suite from the src/Validation folder using the build.cmd -test command.

Exceptions (if any)
