Thanks to COM Interop, you can still use the Microsoft Script Control from VB.NET and any other .NET language. To do so, you must add a reference to the Microsoft Script Control library (from the COM page in the Add Reference dialog box): this action creates a new reference named Interop.MSScriptControl, which enables you to use the Script control with early binding. The following code uses the Eval method to evaluate a math expression from VB.NET:
Dim sc As New MSScriptControl.ScriptControl()
' You always need to initialize a language engine
sc.Language = "VBScript"
' this is the expression - in a real program it will probably be
' read from a textbox control
Dim expr As String = "12 + 3 * 10"
Dim res As Double = sc.Eval(expr)
' display the result
Console.WriteLine("{0} = {1}", expr, res)
