Am trying to upgrade a customer to .net 4.0 with a new app.
He created a new web site, and points at dedicate app pool (W 2003), and targets 4.0. Gets a page not found error (404).
The app is compiled for .net 4.0. Have made the web.config changes for the 4.0 upgrade:
<compilation defaultLanguage="c#" debug="true" targetFramework="4.0">
<pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"/></system.web>
This same app working in multipel places on multiple servers. Can't figue out what is wrong here.
If I point the web site at a 2.0 application, and change the .net to 2.0, it works. If I then change to .net 4.0, it will not work. So neither the 2.0 or 4.0 application will work on the 4.0 framework.
Tried reinstall/repair of the framework itself. Tried restarting server.
