Hi DNN users,

I am trying to upgrade a DNN site to use DotNet Framework 4.0, however I can't seem to get it to work - any help would be appreciated.

Error - 

404 - File or directory not found.

The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.

This only happens when the Application Framework is set to v4.0, if it is on 2.0 it works fine.
I have tried backing up my Db and Files.
Installing the latest version of DNN in a Framework 4.0 application folder (this is result)

I am developing apps in 4.0 as I use VS 2010 now, and would love to work out how to do this?
Any ideas?

Thanks, your help would be appreciated.

If you don't want to make the web.config changes manually, you can use the XML Merge module to apply the Net40.config file which is located in the install/config directory of your DotNetNuke installation.  This will make all the necessary changes to the web.config file.  You will also need to make sure the apppool for the website is set to run ASP.Net 4.0.

Hi Joe,

I am having a similar issue after upgrading a site 5.6.2 but I cannot find the Net40.config file that you mention.  I have looked in the install folder and I can only see 5 config files and none are called Net40.

You help is appreciated.

Thanks
