Windows Application App.config Files vs. web.config

[Nick Johnson]

I am working to expose functionalitly from a .NET 2.0 assembly (API) as a web
service. The problem I am having is the the API uses the app.config settings
from a windows application to retrieve it's connectionstring.

I have tried adding the entire <connectionStrings> tag from a working
app.config file and placing the contecnts in the <connectionSetrings> tag in
the web.config file without any success.

Here is a portion of the exception that is thrown:

System.NullReferenceException: Object reference not set to an instance of an
object.
at dotnet.API.Properties.Settings.get_Item(String propertyName)
at dotnet.API.Properties.Settings.get_CredentialsConnectionString()
at dotnet.API.dsMasterTableAdapters.PeopleTableAdapter.InitConnection()
at dotnet.API.dsMasterTableAdapters.PeopleTableAdapter.get_Connection()
at dotnet.API.dsMasterTableAdapters.PeopleTableAdapter.InitAdapter()
at dotnet.API.dsMasterTableAdapters.PeopleTableAdapter.get_Adapter()


Thanks for any help...
