Question

I have my validation configuration stored in validation.config in my Business Object project. The config file is set to copy if newer

The business object project is referenced by my web project, therefore, the validation.config copies to the bin folder of my web application.

In my web.config I have the validation configuration redirected:

<enterpriseLibrary.ConfigurationSource selectedSource="System Configuration Source">
<sources>
  <add name="System Configuration Source" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.SystemConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
  <add name="ValidationConfigurationSource" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
    filePath="bin\validation.config" />
</sources>
<redirectSections>
  <add sourceName="ValidationConfigurationSource" name="validation" />
</redirectSections>

However, using procmon I can see it is trying to load the configuration from C:\WINDOWS\system32\bin\validation.config

The source for the FileConfigurationSource doesn’t seem to have anything in it about creating a path using AppDomain.CurrentDomain.BaseDirectory so I’m not sure how relative paths can work with asp.net

How can I get this to work for an ASP.NET application?

I am running on XP using the local IIS server launching in debug mode.

Edit

Sorry, just realized there are two open issues filed for this:

If I come up with a workaround, I will post here.

To fix the code in the Microsoft Enterprise Library source, replace the following method in FileConfigurationSource.cs with the code shown below. The modified code moves the check for file existence after the creation of a rooted file path.

    private static string GetRootedCurrentConfigurationFile(string configurationFile)
    {
        if (string.IsNullOrEmpty(configurationFile))
            throw new ArgumentException(Resources.ExceptionStringNullOrEmpty, "configurationFile");


        string strPath =
            Path.IsPathRooted(configurationFile)
            ? configurationFile
            : Path.Combine(AppDomain.CurrentDomain.BaseDirectory, configurationFile);

        if (!File.Exists(strPath))
        {
            throw new FileNotFoundException(
                string.Format(
                    CultureInfo.CurrentCulture,
                    Resources.ExceptionConfigurationLoadFileNotFound,
                    configurationFile));
        }
        return strPath;
    }
