Roman Bäriswyl commented on LOG4NET-581:
----------------------------------------
[[email protected]]
For projects using Log4Net, I created a Contest Property Wrapper like this one:
{code:java}
private static void SetContextProperty(string propertyName, object value)
{
if (value == null)
{
log4net.LogicalThreadContext.Properties.Remove(propertyName);
}
else
{
log4net.LogicalThreadContext.Properties[propertyName] = value;
}
}{code}
This makes sure that no null values are there.
For newer projects, we moved to Serilog.

> Hello,
> Below is the full exception stack. Exception happens because entryValue is
> null, so attempt to get IsSerializable attribute from GetType() was failing.
