Invalid conversion from type HostIndexedProperty to type Boolean

[DanielGerlach2]

Hello ClearScript Team,

The update to ClearScript 7.5.1 resolved several issues regarding its integration into our application. 👍
See here.

However, I have now discovered a new problem 😟

There are properties defined as Booleans.
e.g.
Public ReadOnly Property AdminMode() As Boolean

When evaluating them via the script engine, I receive the following error message:
ScriptEngine.Evaluate("App.AdminMode") -> Invalid conversion from type HostIndexedProperty to type Boolean

The evaluation of ScriptEngine.Evaluate("App.AdminMode = True"), however, works as expected.

Is there a switch or setting that allows me to change this behavior?
Ideally, only the return value of the property should be evaluated/returned.
Unfortunately, modifying the affected code is not possible, as this can be flexibly utilized and configured by users themselves; consequently, this approach would no longer be manageable or maintainable.

Or is the side effectreferring to related to the MarshalEnumAsUnderlyingType or AcceptEnumAsUnderlyingType attributes?

best regards
Daniel

Hi @DanielGerlach2,

We've tested the following with ClearScript 7.5.0 and 7.5.1. The behavior is identical and correct, as far as we can tell:

Imports System
Imports Microsoft.ClearScript.Windows
Public Class App
    Public Sub New(adminMode As Boolean)
        Me.AdminMode = adminMode
    End Sub
    Public ReadOnly Property AdminMode() As Boolean
End Class
Module Program
    Sub Main(args As String())
        Using engine As New VBScriptEngine
            engine.DisableDynamicBinding = True
            engine.AcceptEnumAsUnderlyingType = True
            engine.MarshalEnumAsUnderlyingType = True
            engine.AddHostObject("App", new App(True))
            Console.WriteLine(engine.Evaluate("App.AdminMode"))
        End Using
    End Sub
End Module

This app prints "True" with both ClearScript versions – 7.5.0 without the enum marshaling flags, and 7.5.1 with and without them. Are you doing something differently?

Thanks!
