Test Web Services form; HTML Widgets tab; "Sample ASP.NET Proxy Page" section removed

On the Test Web Services form, HTML Widgets tab, the "Proxy Page" dropdown allowed you to choose "ASP.NET". This produced some code to proxy HTML Widget calls.

The mechanism was superseded long ago by the External Widget Host application and has therefore been removed.

The "Proxy Page" dropdown now includes a single option, "External Widget Host 6". Selecting this simply changes the "src" attribute in the sample IFRAME code to a sample External Widget Host URL.
