App wont run when adding 'appSettings' to config file

[moondaddy]

I'm running a wpf windows app and want to add the appSettings element to the
config file. when I do, the app wont start up and I get the following
error:

{"The type initializer for 'System.Windows.Application' threw an
exception."}
{"The type initializer for 'System.Windows.Navigation.BaseUriHelper' threw
an exception."}
" at System.Windows.Application..ctor()\r\n at
DiagramTool_v1.App..ctor()\r\n at DiagramTool_v1.App.Main() in
D:\\nwis\\Apps\\WPF\\DiagramTool_v1\\DiagramTool_v1\\obj\\Debug\\App.g.cs:line
0\r\n at System.AppDomain.nExecuteAssembly(Assembly assembly, String[]
args)\r\n at System.AppDomain.ExecuteAssembly(String assemblyFile,
Evidence assemblySecurity, String[] args)\r\n at

System.Threading.ThreadHelper.ThreadStart_Context(Object state)\r\n at
System.Threading.ExecutionContext.Run(ExecutionContext executionContext,
ContextCallback callback, Object state)\r\n at
System.Threading.ThreadHelper.ThreadStart()"

the app will run when the config file looks like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

<configSections>
</configSections>
<connectionStrings>
<add name="some string...." />
</connectionStrings>
</configuration>


But not like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

<appSettings>
<add key="RunFrom" value="Voyager" />
</appSettings>

<configSections>
</configSections>
<connectionStrings>
<add name="some string...." />
</connectionStrings>
</configuration>

Note: this DID work in a .net 1.1 app. Am I supposed to put the
appSettings element somewhere else now? Isnt there a tool I can use to
create config files through a windows UI?

Thanks.

Did not do it for me. I just created a Windows application in C# had a Form,
with one button and to show a messagebox in the button click event. I add
the information you gave to the config file, it opened ok!

keep a break point at Application.Run and debug. Is not even going beyond
it?

He's doing WPF. YOu have to create a WPF Windows Application to test out
what he's doing.

moondaddy -- how are you adding the info to the config file? Are you using
C# or VB?

Ahh WPF.. never gone there yet.. You will get better response from WPF
specific group..

The problem is there isn't one, per se. There's
microsoft.public.windows.developer.winfx.avalon, but it doesn't have a lot
of traffic.

Other than that, there is the MSDN forum for WPF. I think this guy has the
support option from MS, though, because eventually they will answer his
question. In order for that to happen, he has to post it to one of the
managed newsgroups, of which this is one.

Hi Moondaddy,

Regarding on the WPF application, normally adding AppSetting keys should
not affect your application's runtime behavior. From the error message you
posted, the problem seems occur at type's initialize time. If possible,
would you post some detailed code snippet (you can try creating a
simplified project which can repro the same error behavior) so that we can
perform some further investigation on this?

Sincerely,

Steven Cheng

Thanks to all who have been responding.

1) Yes I get support from MS here so I post WPF questions here rather than
the MSND forums (although I go there some as well).

2) Here's the code from the app.config file where I'm having my trouble:


<?xml version="1.0" encoding="utf-8" ?>
<configuration>

<appSettings>
<add key="RunFrom" value="Voyager" />
</appSettings>

<configSections>
</configSections>
<connectionStrings>
<add
name="DiagramTools.Properties.Settings.DiagramToolConnectionString"
connectionString="xxxxxxxxxxxxxxxxxx"
providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>

and when I remove this code all works fine:

<appSettings>
<add key="RunFrom" value="Voyager" />
</appSettings>

does this shed any light?

I found the problem. my solution has many projects and one of them also had
an app config file which also had an appSettings element in it. this
created a conflict when I added another appSettings element to a different
project.
