By default you wont get the ConfigurationManager. You need to add the System.Configuration DLL mannually from the Add Reference. Once you add this dll and get the ConfigurationManager, you can see the options to open the exe configuration.

How to access app.config in a library
05-Oct-07
Hi
I have a library project that implements a Business Layer for a we
and a desktop applicatio
All my business classes are in this lib, so I have here the connectio
string to database as app setting (in app.confi
The section in app.config looks like thi
<applicationSettings
<BB.InsuranceService.Lib.Properties.Settings
<setting name="BBAssurConnString" serializeAs="String"
<value>Data Source=.\SQLEXPRESS;Initia
Catalog=MyDB;Integrated Security=True</value
</setting
</BB.InsuranceService.Lib.Properties.Settings
</applicationSettings
App.config belongs to project name BB.InsuranceService.Li
I have a utility class with a Static member which should return th
Connection string, to use it in constuctors of BO, as belo
namespace BB.InsuranceServic
class DBUtilit
public static string ConnectionString(
retur
ConfigurationSettings.AppSettings.Get("BBAssurConnString")
But I have two problems
First, I get the following warning
Warning 1 'System.Configuration.ConfigurationSettings.AppSettings' i
obsolete: 'This method is obsolete, it has been replaced b
System.Configuration
System.Configuration.ConfigurationManager.AppSettings..
But I cannot find ConfigurationManager, it is not i
System.Configuration. Where is this
And the second problem is (and this is a problem), the call t
ConfigurationSettings.AppSettings.Get("BBAssurConnString"); return
null
I have the app.config in the same folder as the library project
And as I mentioned, this library is used by two projects, a web an
and win forms project. Web app has its own web.config (without an
connection string setting) and Win forms project also has its ow
app.config file (also without any connection string setting
Can anyone help me with this, please
Thanks

Re: How to access app.config in a library
For the Web application, if there is not a physical separation of the tiers,
meaning the Web server has the logical tiers of UI, Business, and Data
Access Layer on the Web server, then Web.config can have an AppSettings in
it for the SQL connection string. Web.config is the Root.Config for the
entire Web application, The logical tiers will look for the AppSetting to
be in the Web.config
For the Windows desktop application, a DLL.Config can be applied to a DLL.
The way you use a DLL.config for a DLL is the DLL.Config must be in the
Windows/system32 directory where DLLHOST.exe resides that host all DLL(s).
The other options you may have is to create you own DLLConfig.INI file and
make your DLL get the connection string information for the INI file, or you
pass the Connection string as a parameter to the Business Object.
