问题
Does anyone know what this particular exception mean and how to fix it?
Note, that I am not asking for help on suppressing it in the Exceptions dialog. I want to understand the root cause of it and how to fix the cause itself, if at all possible.
Thanks.
P.S.
The line that causes FCE is:
using (ServiceHost host = new ServiceHost(typeof(WcfPortal)))

EDIT
The issue does not produce itself after upgrading to .NET 4 and VS2010. I guess MS fixed it.
回答1:
I've had a similar issue in the past when dealing with WCF. In this case, it was basically MS code swallowing an exception but it was still caught as a FCE when in debug mode. See this link for more info.
If your issue is in WCF, an appropriate workaround is to suppress the FCE dialog since you can't do much about it. If it's not WCF related, I suspect that it might be in another base class library or third party dll you are using. Either way, not much you can do about it. In my experience, I've never seen this exception lead to anything meaningful.
If you believe it might be of some value, you might want to post a bit more contextual information about where the exception originated from so that folks can chime in and be of assistance.

In my case the following solution worked:
- I found configuration (settings) file, my program used (in the exception details).
- I stopped debugging.
- I deleted configuration file from the location, I found.
- I recompliled my app..
Hope will work in your case too :)
回答3:
I've just wasted an hour or so, after hitting exactly the same problem.
I have a WPF app, which was successfully calling a Web Service and getting some data.
But... this morning, I went into the Exceptions dialog in VS2008, and asked it to throw an exception on "Common Language Runtime Exceptions".
From then on, my app would crash as soon as it hit the line to initialise my webservice variable:
MikesWebServiceSoapClient client = new MikesWebServiceSoapClient ();
A first chance exception of type 'System.Configuration.ConfigurationErrorsException' occurred in System.Configuration.dll Additional information: This element is not currently associated with any context
I did read the comments in this StackOverflow thread, but was confused. In the Exceptions dialog, I could disable the "System.Configuration" exceptions from being thrown... but this exception WOULD still occur. And I didn't have any other exceptions relating to System.Configuration that I could untick.
I even tried leaving "Common Language Runtime Exceptions" ticked, but unticking every one of it's children. But my app would still crash with an exception...
Eventually, I realised that in the Exceptions dialog, I needed to add a new Exception type called "System.Configuration.ConfigurationErrorsException", click on OK, then UNTICK this new Exception type.
Now, my app would run, the exception would silently occur, but the app would keep running.
I do like WPF, but it's ridiculous how much time I waste chasing down silly problems like this that've been around for years.
I wouldn't mind, but this was a WebService variable created by VS2008... and it's always worked fine. Until you ask WPF to pay attention to exceptions, that is...

Silverlight web services.
Re the above, after much experimentation, I found what works to solve this bug --you change everything from Debug to Release. This means changing all attributes such as (from ="true") in the web.config file, as well as setting the Configuration Manager of Visual Studio from Debug to Release.
When you do this, the bug disappears. And my original workaround is wrong--no need to change from a Dataset to a class, as I suggested. Once you make the change to Release the bug disappears.
