System.Threading.ThreadAbortException in classlibrary - wpf

Question

I have a wpf application which will call a class library as a plugin to connect with wcf service every time. When call a service method in class library, it will give the above exception. And the exception message is
er = {Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.}Even the stack trace also has the above message. What is the solution?

I'm just guessing here, as you don't provide much code. But in your main application make sure to add the following eventhandlers;
DispatcherUnhandledException
AppDomain.CurrentDomain.UnhandledException
TaskScheduler.UnobservedTaskException
As also documented in this thread:

Log your exceptions with something like Log4net. Regarding WCF, all calls should be wrapped in a try catch block.
If your error is WCF related you can take your service's app.config file and add the following configuration:
<system.diagnostics>
<sources>
<source name="System.ServiceModel"
switchValue="Information, ActivityTracing"
propagateActivity="true" >
<listeners>
<add name="xml"/>
</listeners>
</source>
<source name="System.ServiceModel.MessageLogging">
<listeners>
<add name="xml"/>
</listeners>
</source>
<source name="myUserTraceSource"
switchValue="Information, ActivityTracing">
<listeners>
<add name="xml"/>
</listeners>
</source>
</sources>
<sharedListeners>
<add name="xml"
type="System.Diagnostics.XmlWriterTraceListener"
initializeData="c:\temp\wcf.svclog" />
</sharedListeners>
This will log all WCF activity to c:\temp\wcf.svclog which you may view using the tool SvcTraceViewer.exe located in your win sdk directory.
Hope it helps
