Hello,
I have been searching the net, MSDN, google groups and can't seem to
find anything about what is happening to me.
I have developed a application using VB.Net 2.0 and deploy it using
ClickOnce over a private network. I use AppSettings.Get("") to
retrieve values form my app.config and I use
AppSettigns.Settigns("").value = value to set values.
This has been working fine for a long time (10 months). All of a
sudden I am now coming across errors when I try to save the
configuration. This is how I save it:
Dim config As Configuration =
ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
config.AppSettings.Settings("").Value = newValue
'9-12 more settings set
' Save app.Config file
config.Save(ConfigurationSaveMode.Full, True)
When I call this method I get a "An extension of name
'clientCredentials' already appears.. Extension names must be
unique... line 237"
At line 237 is information that is not in my normal app.Config file
when i develop. My Config file is less that 100 lines. It seems
the .net framework uses the app.Config for it's own settings also.
The 'clientCredentials' is found in a section below my "AppSettings"
in a tag
<system.serviceModel>
<extensions>
<behaviorExtensions>
<add name='clientCredentionsl.....>
I have no idea where this came form or why it would try to create a
send one or what but I have no idea what to do or proceed.
Any help would be appreciated,
Jordon
