Monday, March 29, 2010 2:21:12 AM
To check your target web server environment for installed CLR versions you can use the follogin script which runs through the registry to determine the installes CLR versions on a host. Just paste the text below into a .aspx file. That' all.
<%@ Page Language="VB" %>
<%@ Import Namespace="Microsoft.Win32" %>
<script runat="server">
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Dim componentsKeyName As String = "SOFTWARE\Microsoft\NET Framework Setup\NDP"
Dim componentsKey As RegistryKey = Registry.LocalMachine.OpenSubKey(componentsKeyName)
Dim instComps As String() = componentsKey.GetSubKeyNames()
For Each instComp As String In instComps
Dim key As RegistryKey = componentsKey.OpenSubKey(instComp)
If instComp IsNot Nothing AndAlso instComp.StartsWith("v") Then
lblVersion.Text = lblVersion.Text & instComp & " SP " & key.GetValue("SP") & ", "
End If
Next
End Sub
</script>
<html>
<head runat="server">
<title>CLR Versions</title>

<body>
<form id="form1" runat="server">
<asp:Label ID="lblVersion" runat="server">Your server is running ASP.NET and the versions are: </asp:Label>
