Chapter 18 Deploying locally

I am having trouble at Try it out 'Configuring the file system' on page 656 step 10. It says my site should work now, unfortunately it doesn't. When I first try to browse to:

http://locahost/

the browser redirects to:

http://localhost/Errors/Error500.asp...=/Default.aspx

and the Runtime Error description says 'The current custom error settings for this application prevent the details of the application error from being viewed.' The first thing I do is set the mode="Off" in this line of the web.config file:

<customErrors mode="On" defaultRedirect="mycustompage.htm"/>

Then I get a configuration error:

'Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive'in this line in the web.config file:
<compilation debug="false" targetFramework="4.0">

After trying a different case then discovering targetFramework is not an option in the intellisense menu I remove it which gives me this:

'Could not load file or assembly 'System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.'

on this line:<add assembly="System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/></assemblies></compilation>This is where I copy the web.config from the Source/Final folder thinking there may be an issue with myn. I get the same result.

Im a bit confused, what have I done wrong. The pages inside my begASPNET/Site dir inside VS 2010 work perfectly.

TYIA for your help

It should, if you had created a 3.5 site from the beginning, but judging from your description, you've created a 4.0 site instead. Two quick ways to fix that:

1. Simply run the site as a 4.0 site under IIS by choosing that as the target framework. For all practical purposes, you *have* a 4.0 site, even though you only used 3.5 options.

2. Downgrade the site and fix and remaining problems. In Visual Studio, open the site's Property Pages and on the build tab change the target framework to 3.5. This changes the web.config by changing assembly references and the target framework.

Hope this helps,

HI Imar - Thank you for your reply. I have been away for a few days completeting a course to compliment my learning in your book....

Gee I wonder how I ended up building this for 4.0 - I dont remember an option that asked me this. I guess it was beause I am using VS 2010, is this the default behaviour which needs to be changed to 3.5

Thanking you

There's a target drop-down in the File | New Web Site and File | New Project dialogs. For Visual Studio 2010, it defaults to .NET 4, but you can manually set it to 3.5, 3.0 and 2.0.

For Visual Studio 2008, the default was .NET 3.5 but you could also set it to 3.0 and 2.0 (but not to 4.0 as frameworks are not forwards compatible).

Cheers,
