Asp.Net 1 -> Asp.Net 2 upgrade - Machine.Config - unrecognized parameter

I am working on upgrading a web app to asp.net 2 from 1.

VS 2008 did its conversion things, and everything is building successfully and has been converted to a web application via the appropriate menu item in VS 2008.

On launching the site using the Asp.net development server I am receiving a configuration error on the appsettings line in the mach开发者_StackOverflow社区ine config of Unrecognized attribute 'restartOnExternalChanges'.

The app targets asp.net 2 in the projects properties in VS, and the error page indicates similar : Version Information: Microsoft .NET Framework Version:2.0.50727.3053; ASP.NET Version:2.0.50727.3053

The error message seems to indicate I am trying to run this in an asp.net 1 environment, but surely that isnt the case, and if so how do I rectify this.

Any help would be appreciated

Thanks,

It sounds like your 2.0 framework is ganked. I know you are running in the dev server but do you have an option in IIS for version 2.0? Re-Run the Microsoft .NET framework V2 installer.

I would just install .NET 3.5SP1 , link is here
