Getting a strange exception with the MS Exception Handling Block

Question

I've created a very basic Logging block and Exception Handling block. In my code, I went to go test the Exception Handling (I know the Logging block works) with the following:

    public void RunScriptClean()
    {
        try
        {
            throw new FileNotFoundException();
        }
        catch (FileNotFoundException ex)
        {
            var b = ExceptionPolicy.HandleException(ex, "Logging Policy");

            if (b)
                throw;
        }
    }

However, on the very first line of the catch block, I get this long winded exception and my application crashes:

Exception occured: The current build operating (build key Build Key [Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.ExceptionPolicyImpl, Logging Policy]) failed: The type 'Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' cannot be resolved. Please verify the spelling is correct or that the full type name is provided. (Strategy type ConfiguredObjectStrategy, index 2).

I have absolutely no idea what it's referring to when it says the type cannot be resolved. I've added references to Microsoft.Practices.EnterpriseLibrary.Common/ExceptionHandling/Logging and Ms.Practices.ObjectBuilder2. This one class has using Microsoft.Practices.EnterpriseLibrary.ExceptionHandling included at the top.

Added a screenshot of the configuration tool looking at my AppConfig file:

I'm sure I'm missing something basic, but it's tough to find a tutorial for EAB 4.1-- CodeProject has a lot for the original versions but I couldn't make much of them...

Edit I tried creating a new Formatter and naming it TextExceptionFormatter but that didn't change anything. Wasn't sure if maybe some how the FormatterType property on my Logging Handler was tied to that node.

And the actual block of XML from App.config:

  <exceptionHandling>
    <exceptionPolicies>
      <add name="Logging Policy">
        <exceptionTypes>
          <add type="System.Exception, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
            postHandlingAction="NotifyRethrow" name="Exception">
            <exceptionHandlers>
              <add logCategory="General" eventId="100" severity="Error" title="Enterprise Library Exception Handling"
                formatterType="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.TextExceptionFormatter, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
                priority="0" useDefaultLogger="false" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging.LoggingExceptionHandler, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
                name="Logging Handler" />
            </exceptionHandlers>
          </add>
        </exceptionTypes>
      </add>
    </exceptionPolicies>
  </exceptionHandling>

I found this SO question: Cannot resolve type runtime error after registering the Enterprise Library into the GAC but even after changing the Version segment of the fullName attribute my app still behaves the same.

Answer 1

Alright, I was able to find a sample application that used the Logging handlers. Turns out I needed a reference to ExceptionHandling.Logging:

Microsoft.Practices.EnterpriseLibrary.Common
Microsoft.Practices.EnterpriseLibrary.ExceptionHandling
Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging ****
Microsoft.Practices.EnterpriseLibrary.Logging
Microsoft.Practices.ObjectBuilder2

Where as I only had a references to:

Microsoft.Practices.EnterpriseLibrary.Common
Microsoft.Practices.EnterpriseLibrary.ExceptionHandling
Microsoft.Practices.EnterpriseLibrary.Logging
Microsoft.Practices.ObjectBuilder2
