WPF “not a valid value for property” error for attached property even though it works as expected

I have a TextBox with an attached property on it, and Visual Studio gives me an error saying that the property value is not valid, even though it is in fact valid.

I have a TextBox with an attached property on it, and Visual Studio gives me an error saying that the property value is not valid, even though it is in fact valid.

Here's the TextBox:

<TextBox 
    HorizontalAlignment="Stretch" 
    VerticalAlignment="Top" 
    Width="Auto" 
    styleExtensions:TextBoxExtension.BorderStyle="None"/>

And this is the AttachedProperty:

public enum BorderStyle
{
    Rounded,
    BottomOnly,
    None
}

public static DependencyProperty BorderStyleProperty =
DependencyProperty.RegisterAttached(
"BorderStyle",
typeof(BorderStyle),
typeof(TextBoxExtension));

The GetBorderStyle and SetBorderStyle methods are also present, and since they do nothing special, I didn't paste them here.

When I rut it, the program works as expected, all three values for BorderStyle do what they're supposed to (they trigger different changes in a Style) and even the visual xaml editor shows the changes as expected, but for some reason Visual Studio keeps giving me this pointless error for this particular TextBox:

'None' is not a valid value for property 'BorderStyle'

The error persists for all three values of the enum. The same attached property is also used somewhere else in a ControlTemplate, on a different TextBox and it doesn't trigger this error.

I've tried cleaning the solution, rebuilding it, deleting the bin and obj folders, deleting the .vs folder, but the error keeps showing up.

Am I doing something wrong here, or is Visual Studio wrong? And if so, is there a workaround to disable this specific error message?

I'm using Visual Studio 2017 15.8.8, and .NET Framework 4.7.03056

Pega 7 Property has one of eleven modes, organized in three sets. The General and Behavior tab designs change, based on the mode and the type of table field selected.

With the help of the ‘Property Mode’ option, we can select the mode. The Pega property mode finds how the system indicates, the property data. Among eleven modes, three are page based modes, three are string-based and the other five are modes executed with Java objects.

The presentation of the ‘General’ and ‘Behavior’ tabs rely on the mode selected.

Be careful while selecting the property type. Once we save a property, we cannot change its type except for a few special cases. Below the
Text – If we want the property to have text strings that can hold line feeds, carriage returns, and tabs, then choose text.

For instance, 20191223 indicates December 23, 2019. It is not necessary for users to enter Date values in this pattern, as different easy options patterns are available.
