I'm trying to upgrade a WCF web service from .NET 3.0 to 4. I've run
As well as changed the Application Pool to use v4.0. I rebuilt the service dll with .NET 4.0 as the target and moved it to the /bin directory on my site.
I'm running into an error that is driving me nuts. Whenever I try to hit the site, I get the following error:
HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid.
The configuration section 'system.serviceModel' cannot be read because it is missing a section declaration
I've tried solutions I've found from googling and nothing is working. I feel like someone more experienced with IIS 7 would know exactly what's wrong. Can anyone help with this issue
