it gets frustrating in my new computers running vista i get so many errors that i need to revert back to my laggy XP computer. i have tried updating patches, SP1 (Visual Studio) the patch to enable debugging, etc but still can get my app to work, i get the cannot debug thingy & tones of errors in web.config - every line! i suspect it has also to do with the difference in IIS 7 so how do i migrate my files to Vista? and what are the patches needed... just to check i have them all.

As you said there are several differences, it took me a while to get it to work...

(in IIS Manager)
You probably saw that the web applications runs in "Applications Pools", I'm using a "Clasic .NET AppPool" (I can't remember if I created it or it's part of the default installation), this App pool uses a "Classic" "Managed Pipeline Mode". And the application you want to run should use as "Behavior" that Application Pool.

Other thing you need to understand is that IIS 7 has a "more modular" installation, this means that there are more "pieces" that you can select/deselect, and there a couple of those that you need to turn on ("Turn Windows features on or off" in control panel), one of those is Windows Authentication (under World Wide Web Services->Security). After turning it on, you should go to your web application (in IIS Manager), look for the Authentication icon and set Windows Authenticatino to "Enabled".

If this doesn't fix your problems, at least will get you on the way. If you still have problems please post the errors you are getting with more detail, may be that will let me remember what other thing is missign (if there is any).

i have this now...

Error    1    It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level.  This error can be caused by a virtual directory not being configured as an application in IIS.    D:\ASPX\ASPX\booking\web.config    33   

when i have a virtual dir already

help

but i can "View in Browser"
 

Check if that Virtual Directory it is also an application: go to IIS Manager, right click over your virtual directory, if there is a context menu "Convert to Application" use it. (Here you can also choose the Application Pool you want to use).

 have done that already... don't fix the problem... i have a feeling its Vista debugging still isn't too good?

The debugger works, believe me, but the migration to Vista was a p... in the a...

I remember that the first time I opened the project under Vista, the VS made a backup copy of the website inside the same website, I needed to delete the backup or move it elsewhere to make the site work. Make sure that you don't have this backup under your website tree.

I just found this:
