Today, I wanted to create a new Performance Session in Visual Studio to trace an detect some slowly parts in my web application application.
So it easy, I use the wizard to select my website and the different DLLs I want to instrument, I launch everything and what do I get ?
Launch Error: The web site could not be configured correctly; getting ASP.NET process information failed. Requesting 'http://localhost:48185/MyAspApp/VSEnterpriseHelper.axd' returned an error: The information returned is invalid.
PRF0017: Can't launch server for 'C:\.....\Project'.
Why this error occurs ? How to correct it ? That's what we'll see here ! [Plus]
