VS 2022 Community does not recognize Master Page and other controls
I recently installed Visual Studio 2022 Community and loaded the web site I have been working on. The file text in all my files is covered with squigglies. VS does not recognize most of the objects referenced in my code, starting with the first line of most of my .aspx pages, which is a reference to a Master Page. I get a squiggly under the line '<%@ Page Language="VB" MasterPageFile="Ppm.master" AutoEventWireup="false" ...' and the error message "BC3002 Type 'Web.UI.MasterPage' is not defined." Following is the code on my master page PPM.Master.aspx and PPM.Master.vb. as well as the referencing code in one of my web pages.

I would like to continue debugging and revising this app, as I had been doing prior to installing VS 2022. How can I reconcile my app with this newer version of Visual Studio Community?

I am currentnly using vs2022, and am able to freely open and work on asp.net webform projects, even ones that are 15 years old, and they work perfect in vs2022.
So, as a quick test (less then 1 minute of your time), I would try creating a new webforms project, and see if that project works. If that project does not work, then of course you are wasting your time trying to edit and with with previous projects.
So, try creating a new project, this choice:
So, when you create a new webforms project, does it load and run ok?
It stands to reason if you can't create and work on a new project you create, then trying to work on existing projects also will not work.
So, before you try creating the project (or opening a previous one), then make sure all the webforms tools are installed. The webforms workflows are not installed by default in vs2022.
Hence, launch vs2022, from menu -> tools -> get tools and features.
And ensure all of these options are selected:
And then on the right side, select these:
Note how I even selected the RDLC Report Designer, since your project may well have some reports.
After you install the above workflows, then you should freely be able to open previous projects and work on them. And you also now see the additonal project types when creating a new project.
I should also point out by default, vs2022 defaults to a new web forms "live preview" designer. While that new "live preview" is great, renders the webform with a new chrome engine?
It does not correctly support drag + drop from the tool box, and hence before opening (or creating) a webforms project, I recommend you change the default web forms preview and designer back to the legacy one.
Hence, tools->options->Web Forms Designer
So, change back to the Legacy Web Forms designer.
After installing the above workflows, then I am able to freely open and work on previous projects (assuming they opened and work fine with previous versions of Visual Studio).
