vb.net winform application and the enterprise library

[glyn6]

I've used the enterprise library in vb and c# in web apps to access a sql server database and that all works nicely

I'm trying to use it in a vb.net winform application now however and I'm having nowt but hassle.

I've reference the following .DLLs
Microsoft.Practices.EnterpriseLibrary.Data
Microsoft.Practices.EnterpriseLibrary.Common
Microsoft.Practices.ObjectBuilder2
and included them in the bin directory, which is the #1 solution to the problem

I've included the following lines into the app.config

  <configSections>
    <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    <section name="exceptionHandling" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Configuration.ExceptionHandlingSettings, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    <section name="enterpriseLibrary.ConfigurationSource" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ConfigurationSourceSection, Microsoft.Practices.EnterpriseLibrary.Common, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
  </configSections>

I've imported the references too and when the code is executed on the line

Dim db As Database = DatabaseFactory.CreateDatabase("ConnString")

I get the error message

An error occurred creating the configuration section handler for enterpriseLibrary.ConfigurationSource: Could not load file or assembly 'Microsoft.Practices.EnterpriseLibrary.Common, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) (C:\dev\prog1\bin\prog.vshost.exe.Config line 7)

Where "ConnString" is also in the app.config and is a connection string that also works in the web app.

Any ideas as to why it's working fine for web apps but not for win apps?
Thanks

The public key tokens in app.config and appname.exe.config are case sensitive, and must be in the same case or this error will occur. Make sure that the public key tokens are either upper case in both or lower case in both.

They match, I double checked and it rebuilds the appname.exe.config file whenever I build the project and it doesn't

It's the line

    <section name="enterpriseLibrary.ConfigurationSource" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ConfigurationSourceSection, Microsoft.Practices.EnterpriseLibrary.Common, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

in app.config that seems to be affected, removing this line gives the error message

Configuration system failed to initialize

So I'm fairly confident in that at least ;-)

I tried using all uppercase instead of lower to make sure that wasn't a problem, so B03F5F7F11D50A3A instead of b03f5f7f11d50a3a and it had the same error though oddly, the error message put it in in lowercase. :-S

Turns out, when I added the reference to the DLLs it also added a few lines further down the app.config file.

  <enterpriseLibrary.ConfigurationSource selectedSource="System Configuration Source">
    <sources>
      <add name="enterpriseLibrary.ConfigurationSource" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ConfigurationSourceSection, Microsoft.Practices.EnterpriseLibrary.Common, Version=4.1.0.0, Culture=neutral, PublicKeyToken=null " />
      <add name="File Configuration Source" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Version=4.1.0.0, Culture=neutral, PublicKeyToken=null" filePath="c:\Shared.config" />
      <add name="System Configuration Source" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.SystemConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Version=4.1.0.0, Culture=neutral, PublicKeyToken=null" />
    </sources>

  </enterpriseLibrary.ConfigurationSource>

I removed all references to the Microsoft.Practices stuff and it works. Makes a change to be over referenced rather than under referenced ;-)

Hope this helps somebody else out
