6.3. How to Use Data Virtualization

To enable the data virtualization, you should apply a custom attribute to your field. In order to do that, you can use the instructions below.

Instructions on enabling data virtualization

Locate the declaration of a field you want to virtualize

Add a custom attribute as shown below (C#):

using System;
using System.Reflection;

class YourClass
{
    [Obfuscation(Feature = "virtualization", Exclude = false)]
    bool yourField;
}

For Visual Basic .NET:

Imports System
Imports System.Reflection

Class YourClass

    <Obfuscation(Feature:="virtualization", Exclude:=False)>
    Dim yourField As Boolean
    
End Class

Note

Virtualization can significantly slow down the speed of code execution, so please use this feature wisely.
