Msgstr "Unrecognized configuration.

I was working on a project in VS2005 that used a local connection to an access database.

Last week I installed the .NET framework 3.5 for use with another project, as well as with VS6.

I returned to my VS2005 application, and suddenly there are big problems:

In the designer, for any class using my OLEDB connection, the following was shown:

Cannot pass an object of type 'System.Configuration.DefaultSection' to type 'System.Configuration.ConnectionStringsSection'. Hide

And when I started the application, I encountered the following exception at startup:

"Unrecognized connectionStrings section configuration."
