title: How to Override Web.config values with Azure KeyVault in .NET Framework 4.7.1
body: <p>How can I implement Microsoft's Azure KeyVault in a ASP.NET Framework 4.7.1 WebForms application to override values in <code>web.config</code> with values from KeyVault? I do see references that we need a minimum version of .NET Framework 4.7.1 in order to do it but the examples Microsoft provides are for .NET Core. I have my configs as <code>web.config</code> files instead of <code>appsettings.json</code>. I also have <code>Global.asax.cs</code> files instead of <code>Startup.cs</code> and <code>Program.cs</code>.</p>
