Type: Bug
Components: Core
Versions: 1.2.9
Reporter: Nicko Cadell
Assigned to: Nicko Cadell
Priority: Minor
Fix For: 1.2.10
System.Diagnostics.Trace may throw exception if AppDomain does not have config
file.
If the AppDomain has been created programmatically it is possible that it does
not have a config file set. It has been reported that an exception can be
generated on certain platforms in this situation.
The exception is:
System.Reflection.TargetInvocationException: Exception has been thrown by the
target of an invocation. --->
System.TypeInitializationException: The type initializer for
"D2L.Mail.MailService" threw an exception. --->
System.TypeInitializationException: The type initializer for
"log4net.Core.LoggerManager" threw an exception. --->
System.TypeInitializationException: The type initializer for
"log4net.Util.LogLog" threw an exception. --->
