Hi,

I have a couple of web projects both using V2.6 templates under .NET 4. I want to now use V3.1

I have successfully migrated the project files to V3, loaded the project and generated the code (including some manager templates that I brought over from V2.6)

I have religiously removed all references to V2.6 support libraries and used the V3.1 versions. The solution builds perfectly however when I run the applications (that did work fine under 2.6) i get

Server Error in '/' Application.

The connectionString Key used in configuration files has been changed. The default pattern used now is: ConnectionString.{$ProviderName} Please check the app.config file in the generated code.

Aah sorted thanks works a treat !!
