Exception handling error

Hello,

I built a new Smart Client Application using a freshly installed copy of the source and Enterprise Library 3.1.

In ShellApplication.cs I changed the following code to test exception handling.

private static void RunInDebugMode()
{
HandleException(new Exception()); // New code

Application.SetCompatibleTextRenderingDefault(false);
new ShellApplication().Run();
}

When the code executes I get this error:

An error occurred creating the configuration section handler for exceptionHandling: Could not load file or assembly 'Microsoft.Practices.EnterpriseLibrary.ExceptionHandling, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) (\\Projects\\SmartClientDevelopmentSolution1\\bin\\Debug\\Shell.vshost.exe.config line 14)

I tried using both the strong name and non-strong name versions of the Enterprise Library but get the same error. I also experiment with setting the PublicKeyToken to null as shown above. None of this worked.

Is anyone else having this issue? Any suggestions on how to fix it?

Thank you,

Rick

Hi Rick, you just found an issue. The shell project has references to the signed assemblies of Enterprise Library and Microsoft.Composite.UI. In the app.config those assemblies appears as unsigned.

In order to solve it, do the following:

Open App.config. Now you have to add the Enterprise Library assemblies public token (b03f5f7f11d50a3a) to those lines where a type of the Enterprise Library is being declared

For example, from this
<section name="exceptionHandling" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Configuration.ExceptionHandlingSettings, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" />
to this:
<section name="exceptionHandling" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Configuration.ExceptionHandlingSettings, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling, Version=3.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
Also you have to include the public token of the Microsoft.Composite.UI assembly (31bf3856ad364e35):
From this:
<add type="Microsoft.Practices.CompositeUI.EventBroker.EventTopicException, Microsoft.Practices.CompositeUI, Version=1.0.51205.0, Culture=neutral, PublicKeyToken=null" postHandlingAction="NotifyRethrow" name="EventTopicException">
to this
<add type="Microsoft.Practices.CompositeUI.EventBroker.EventTopicException, Microsoft.Practices.CompositeUI, Version=1.0.51205.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" postHandlingAction="NotifyRethrow" name="EventTopicException">
For your convenience, here is a clean fixed app.config:

Thank you for your response. I was unable to use your config file because there are a number of differences.

When I changed the two config line as you suggested, the error changed to:

Could not load file or assembly 'Microsoft.Practices.CompositeUI, Version=1.0.51205.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Changing this token to null seems to work. Maybe you can confirm?

Here's is my entire config file for your reference:

Well i shall not add anything else after such a vivid explanation... just on important thing... If u are moving from older enterprise library or CAB dll's make sure the path of your references are correct as that might create problems.

Not sure if this is the same error message I got a while back. I seem to recall it though...
I had a 3 tier app and when I got the message I had to add the references to all 3 items in the Enterprise Library (Exceptionhandling, ExceptionHandling logging, Logging)
in both the web (GUI) layer, business layer and Data layer as they were all separate projects.
