I'm new to php but familiar with visual studio (vb, c#).
Now I've started a project with symfony (php7.4) and wanted to try PHP Tools in Visual Studio 2019.
So I created a new project with existing files.
After configuring everything, installing xdebug etc I wanted to try the debugger.
The browser opens and then shows a 'not found':
The requested resource /?XDEBUG_SESSION_START=7A0A4811 was not found on this server.
Then I started a fresh new php project and started debugging and that one worked.
Am I missing something in de configuration/setup when creating a project for existing files?
