Azure Pipelines - VS Test task fails upon providing filter criteria

In my Azure Pipeline, i am trying to build the code and run the code. So i have included "NuGet Restore", "Build Solution" and "VS Test" task. When i am trying to apply filter criteria in VS Test, it shows error that no Test case found with in that search criteria;. Can any one help me in this case.

My Test Suite will Look like.

    // [Category("Enrollment")]
    // [Category("Regression_TS")]
    // [Test, TestTimeOutValue, Parallelizable(ParallelScope.Self), TestDescription("Enroll_001 - Enroll Button\n" +
    //    "Enroll_002 - Log In to Business\n" +
    //    "Enroll_003 - Log Out of Business")]
