it sounds like you have a custom VS plugin/designer that can not detect the project type.
Visual Studio 2022 considering Desktop application as ASP.Net & generating errors

I have developed a desktop application using Visual Studio 2022.
I then developed a web application ASP.net with Visual Studio 2022.
Now, whenever I launch the desktop application, VS considers it an ASP.net application, and is generating errors by the hundreds, as though it would be an ASP.net application.
Is there a way to separate a Microsoft Net.Framework 4.8.1 application from an ASP.Net application, so that they don't interfere with each other.

Anonymous2024-04-03T01:45:32.7933333+00:00 Hi @Simon , Welcome to Microsoft Q&A,
Are they under a solution? Did you know there is an option to set the current startup project? Did you start the wrong project? Is there any more clarification?

2024-04-03T13:37:15.02+00:00 Of course I started the correct project. But it generates tons of error message asking about each control "is this a web or Windows item?
When I click on Help About in VS, it shows that it is Microsoft Net.Framework and in thelist of installed products it lits ASP.Net.
And that is why every single control keeps generating the same message.
What can you advise?

In the project explorer windows, right click the project file you wish to remove and select "Remove".
