Read-only properties were always possible in VB.NET in this format:
Public Class Foo
Private _MyProperty As String = "Bar"
Public ReadOnly Property MyProperty As String
Get
Return _MyProperty
End Get
End Property
End Class
The new version of Visual Basic allows a short hand for the property declaration like so:
Public Class Foo
Public ReadOnly Property MyProperty As String = "Bar"
End Class
The actual implementation that is generated by the compiler is exactly the same for both examples. The new method to write it is just a short hand. The compiler will still generate a private field with the format: _<PropertyName>
to back the read-only property.
