For a couple of months now I've been running Windows Vista and Visual Studio 2005 without major problems (other than the commonly known ones). Since the first day of this setup I have been working on solutions that inlcude from one to many ASP.NET web applications. All of them are configured to use IIS rather than the built in web server. For all that time, everything was working fine until recently...
One of those days, while opening one of the solutions in Visual Studio, I was presented with a message telling me that my site is configured to use ASP.NET 1.1:
---------------------------
Microsoft Visual Studio
---------------------------
The site 'http://localhost/WebSite' is currently configured for use with ASP.NET 1.1.4322.573. Microsoft Visual Studio has been designed for use with ASP.NET 2.0; if not configured some features may make incorrect assumptions, and pages designed with the tool may not render correctly.
Would you like the site to be configured for use with ASP.NET 2.0?
---------------------------
Yes No Cancel Help

Needles to say that there were no changes made to IIS configuration of Application Pools or the pool the site is running on, but just to be sure, I've checked IIS Manager. The pool for the site was ASP.NET V2.0. I have agreed and allowed Visual Studio to make the "necessary" change. Needles to say, that nothing was changed in scope of application pools by Visual Studio. Fortunately, my solution kept working after that... for few days.
After few days I've got the very same message. Again, nothing was changed in IIS. This time I decided to leave my supposedly ASP.NET 1.1 in place. Of course everything worked after that also. Including debugging! But then I have the same message every time I open any of the solutions :-(.
I have found that other people also had this problem, and "aspnet_regiis -i" helped them, but it doesn't work for me :-(
Today I noticed that it gets worse. Now I get the message every time I open any of my solutions that include web sites :-(
