Get Feature is enabled or disabled in D365FO X++

 Issue: Feature is enabled or disabled to get in customize ISV/VAR/USR model. Since it was defined as internal class by MS, and which can't be accessible in reference model.

Workaround solution (X++) in ISV/VAR/USR model: Without using MS OOB class.

IdentifierName featureEnableFeature = 'Dynamics.AX.Application.<>';

        FeatureManagementState featureManagementState;

boolean isFeatureEnabled = false;

        select firstonly featureManagementState

            where featureManagementState.Name == featureEnableFeature ;

        if (featureManagementState.IsEnabled)

        {

            isFeatureEnabled  = true;

        }
