Obsolete Attribute

The ObsoleteAttribute in .NET Framework is used to mark types or members as obsolete, indicating they will be removed in future versions. This helps prevent breaking existing code that relies on these elements. Here's an example:

using System;

public class MyClass
{
    [Obsolete("Method1 is deprecated, please use Method2 instead.", true)]
    public void Method1()
    {
        // Deprecated code here
    }

    public void Method2()
    {
        // New code here
    }
}

In this example, calling Method1() will raise a compilation error due to the true parameter, enforcing the use of Method2() instead.
