How can I set the version of .Net framework used while creating IIS vitual directory?

Question

I have a method that creates a virtual directory. How can I set the .Net framework to version 2 while I create the virtual dir?

My method looks like this so far:

private static void CreateVDir(string metabasePath, string vDirName, string physicalPath)
    {
        //  metabasePath is of the form "IIS://<servername>/<service>/<siteID>/Root[/<vdir>]"
        //    for example "IIS://localhost/W3SVC/1/Root" 
        //  vDirName is of the form "<name>", for example, "MyNewVDir"
        //  physicalPath is of the form "<drive>:\<path>", for example, "C:\Inetpub\Wwwroot"
        Console.WriteLine("\nCreating virtual directory {0}/{1}, mapping the Root application to {2}:",
                          metabasePath, vDirName, physicalPath);

        DirectoryEntry site = new DirectoryEntry(metabasePath);
        string className = site.SchemaClassName;
        if ((className.EndsWith("Server")) || (className.EndsWith("VirtualDir")))
        {
            DirectoryEntries vdirs = site.Children;
            DirectoryEntry newVDir = vdirs.Add(vDirName, (className.Replace("Service", "VirtualDir")));
            newVDir.Properties["Path"][0] = physicalPath;
            newVDir.Properties["AccessScript"][0] = true;
            // These properties are necessary for an application to be created.
            newVDir.Properties["AppFriendlyName"][0] = vDirName;
            newVDir.Properties["AppIsolated"][0] = "1";
            newVDir.Properties["AppRoot"][0] = "/LM" +
                                               metabasePath.Substring(metabasePath.IndexOf("/",
                                                                                           ("IIS://".Length)));

            newVDir.CommitChanges();

            Console.WriteLine(" Done.");
        }
        else
            Console.WriteLine(
                " Failed. A virtual directory can only be created in a site or virtual directory node.");
    }

Answer 1

The "ScriptMaps" property is where the configuration mappings get stored. i.e. That's where you can map *.aspx files to get processed by ASP.Net. Here's an example.

Answer 2

After you have created the virtual directory, you can run aspnet_regiis -s from the .NET framework directory of your choice.

On my sytem, the command would look something like this:

C:\Windows\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis -s W3SVC/1/ROOT/SampleApp1

I have done this from a custom action in my installer successfully.
