How to write nested classes in VB.net?

Nested classes are those classes that are contained in another class declarations. The below program in VB.net will demonstrate this

Namespace ConsoleApplication1
	Class Program
		Private Shared Sub Main(args As String())
			Dim objOuterClass As New OuterClass()
			objOuterClass.SayHelloFromOuterClass()
			Dim innerClass = New OuterClass.InnerClass()
			innerClass.SayHelloFromInnerClass()
		End Sub
	End Class
	Class OuterClass
		Public Sub SayHelloFromOuterClass()
			Console.WriteLine("Hello from Outer Class")
		End Sub
		Public Class InnerClass
			Public Sub SayHelloFromInnerClass()
				Console.WriteLine("Hello from Inner Class")
			End Sub
		End Class
	End Class
End Namespace
