Hello,

I got the following error when opening my web site after using the Copy Web Site feature in Visual Web Developer express 2010 to copy my web site from the source site to the remote site.

Server Error in '/' Application.
--------------------------------------------------------------------------------

Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive.

Source Error:


Line 11: <system.web>
Line 12: <customErrors mode="Off"/>
Line 13: <compilation debug="false" strict="false" explicit="true" targetFramework="4.0"/>
Line 14: <authentication mode="Forms">
Line 15: <forms loginUrl="~/Account/Login.aspx" timeout="2880"/>


Source File: \\filer\mass$\windows\domains\tau-mweb\web.config Line: 13


--------------------------------------------------------------------------------
Version Information: Microsoft .NET Framework Version:2.0.50727.3623; ASP.NET Version:2.0.50727.3618

When I comment out this attribute it causes build errors in my app. Any ideas on where to go from here?

Any help much appreciated!
Thanks!

Hi there,

Take a look at this:

Your Application Pool is configured to run under .NET 2, not .NET 4. The targetFramework attribute is part of .NET 4, hence the error.

Make sure the application pool is set up to run under .NET 4 as explained in the book.

Cheers,

Imar
