Am trying to upgrade a customer to .net 4.0 with a new app.<br />
<br />
He created a new web site, and points at dedicate app pool (W 2003), and targets 4.0. &nbsp;Gets a page not found error (404).<br />
<br />
The app is compiled for .net 4.0. &nbsp;Have made the web.config changes for the 4.0 upgrade:<br />
&lt;compilation defaultLanguage=&quot;c#&quot; debug=&quot;true&quot; targetFramework=&quot;4.0&quot;&gt;<br />
&lt;pages controlRenderingCompatibil<wbr />ityVersion<wbr />=&quot;3.5&quot; clientIDMode=&quot;AutoID&quot;/&gt;&lt;/s<wbr />ystem.web&gt;<wbr /><br />
<br />
This same app working in multipel places on multiple servers. &nbsp;Can't figue out what is wrong here.<br />
<br />
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. &nbsp;So neither the 2.0 or 4.0 application will work on the 4.0 framework.<br />
<br />
Tried reinstall/repair of the framework itself. &nbsp;Tried restarting server.<br />
<br />
Stuck!<br />

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.

ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications
