I new a web form in VB (the same question in C#) without new a project. While the automatic completion not work in VS 2022.

not working in VS 2022.

I'm sure I have installed IntelliCode and enabled it in Tools->options->Auto list members. And this function even works well with Python.

This function works well in VS 2019 (also a single aspx file without build a project), but why it doesn't work in 2022?

It works well in VS 2019.

Looking for your reply! Thanks a lot!

    I have solved this problem by myself. This is my fault.

    A Web.config file is nessary. 

    <?xml version="1.0" encoding="utf-8"?>  <configuration>   <system.web>     <compilation debug="true"  targetFramework="4.7.2" />   </system.web> </configuration>

    I'm terribly sorry for wasting @QiYou-MSFT time. And thinks for your advice again!
