    </providers>
    <rules>
      <rule name="FileMapProviderTest" stopProcessing="true">
        <match url="(.*)" ignoreCase="false" />
        <conditions logicalGrouping="MatchAll">
          <add input="{FileMap:{R:1}}" pattern="(.+)" ignoreCase="false" />

    if (node.Name == "add")
    {
        if (node.Attributes.GetNamedItem("name").Value == "SCI2ConnectionString")
        {

Microsoft has Microsoft.Web.Administration.dll available to help you out, but it requires administrator permissions to execute,

https://www.iis.net/learn/manage/scripting/how-to-use-microsoftwebadministration

It is quite suitable for a WinForms application (such as IIS Manager) to control an IIS server, but can also be used in other types of applications.

I do have a personal project that is a custom MWA implementation that works for some non-administrator cases. If you are interested in it, let me know.
