ConfigurationManager.AppSettings in UserControl's?

Hi,

I am creating a user control using VS2008 & .NET 3.5in which I would like to retrieveAppSettings from an app.config file. The following line of code works fine in a Windows Forms app, but not in a UserControl:

Code Snippet

string strLogFile = ConfigurationManager.AppSettings["LogFile"].ToString();

It complains that "ConfigurationManager" does not exist in the current context. I have included the appropriate using statement:

Code Snippet

using System.Configuration;

The user controlwill build & run ok if I substitute ConfigurationSettings for ConfigurationManager, but that is deprecated and returns null in any case, so it is moot.

Does anyone have any idea why I cannot use ConfigurationManager in a user control?

Thanks.

Dan

Make a manual reference to System.Configuration, then you will see:

System.configuration [notice the small c]

Then you are set.
