Assim como Java, existe o .Net, a vantagem de trabalhar com .Net hoje é maior do que a de trabalhar com Java, visto que um framework apenas supri 3 linguagens distintas VB, C# e C++ em apenas uma IDE (Visual Studio), além de vir com editor pra CSS, JavaScript, AJAX, X/HTML, ASP, SQL Server, entre outras bugingangas mais da Microsoft…

Ué, o Eclipse e o Netbeans tem suporte a muito mais de 3 linguagens distintas em uma mesma IDE. Aliás, o RAD Studio da Embarcadero (ex Borland) também. Aliás, uma pensa de outras IDEs também.

Framework é a biblioteca de componentes, quando digo que o .Net permite trabalhar com 3 linguagens, é que você pode usar os mesmos componente, da mesma forma… e IDE é o ambiente de desenvolvimento.
Exemplo retirado do Help (muito bem organizado por sinal) do Visual Studio, com o componente “System.Windows.Forms” e como pode ser usado:
Visual Basic
[code]Public Sub CreateMyForm()
’ Create a new instance of the form.
Dim form1 As New Form()
’ Create two buttons to use as the accept and cancel buttons.
Dim button1 As New Button()
Dim button2 As New Button()
' Set the text of button1 to "OK".
button1.Text = "OK"
' Set the position of the button on the form.
button1.Location = New Point(10, 10)
' Set the text of button2 to "Cancel".
button2.Text = "Cancel"
' Set the position of the button based on the location of button1.
button2.Location = _
New Point(button1.Left, button1.Height + button1.Top + 10)
' Set the caption bar text of the form.
form1.Text = "My Dialog Box"
' Display a help button on the form.
form1.HelpButton = True
' Define the border style of the form to a dialog box.
form1.FormBorderStyle = FormBorderStyle.FixedDialog
' Set the MaximizeBox to false to remove the maximize box.
form1.MaximizeBox = False
' Set the MinimizeBox to false to remove the minimize box.
form1.MinimizeBox = False
' Set the accept button of the form to button1.
form1.AcceptButton = button1
' Set the cancel button of the form to button2.
form1.CancelButton = button2
' Set the start position of the form to the center of the screen.
form1.StartPosition = FormStartPosition.CenterScreen
' Add button1 to the form.
form1.Controls.Add(button1)
' Add button2 to the form.
form1.Controls.Add(button2)
' Display the form as a modal dialog box.
form1.ShowDialog()
End Sub[/code]
