The following quick SDK sample demonstrates how to list and change the managed runtime version of application pools programatically in IIS 7.
[VB]
Imports System
Imports Microsoft.Web.Administration
Public Class AppPoolSample
Shared manager As ServerManager = New ServerManager()
' Main application processing
Public Shared Sub Main(ByVal args As String())
' Get the apppool to change
Dim iPool As Integer = GetAppPool()
' Get the framework version desired
Dim rtVersion As String = GetVersion()
' Set the apppool runtime
Dim poolToSet As ApplicationPool = manager.ApplicationPools(iPool)
Console.WriteLine(
"Setting application pool '{0}' to runtime version: {1}...", _
poolToSet.Name, rtVersion)
poolToSet.ManagedRuntimeVersion = rtVersion
' Commit the changes and recycle the application pool
manager.CommitChanges()
poolToSet.Recycle()
Console.WriteLine("Your changes have been committed.")
End Sub
' Prompts the user to select an application pool
Public Shared Function GetAppPool() As Integer
Dim pool As String = String.Empty
Dim iPool As Integer = 0
While (Not Integer.TryParse(pool, iPool))
Console.WriteLine("Available ApplicationPools: Managed runtime version")

For i = 0 To manager.ApplicationPools.Count - 1 Step i + 1
Dim appPool As ApplicationPool = manager.ApplicationPools(i)
Console.WriteLine("{3}{0,3}.{3}{1}: {2}", i + 1, _
appPool.Name, appPool.ManagedRuntimeVersion, vbTab)
Next
Console.Write("{0}Choose an application pool to change: ", vbCrLf)
pool = Console.ReadLine()
End While
Return iPool - 1
End Function
' Prompts a user to select the version of runtime they would like
' the application pool to use

Dim rtVersion As String = String.Empty
