------------------------------------------------------------------
We have no plans for 4.5, but it will come sooner or later. Have you tried this
update on your 4.5 installation?
http://support.microsoft.com/kb/2748645
I'm quoting KB2748645:
{quote}Assume that you upgrade an earlier version of the .NET Framework to the
.NET Framework 4.5 on a computer. When you use some third-party controls, you
may receive a System.Security.VerificationException exception. This issue
occurs if the following conditions are true:
The third-party controls use the generic types.
The CLR verifier is enabled by declaring an assembly that is marked as
security-transparent.{quote}
Let us know if the installation of this KB fixes this issue. I can then look
towards updating the FAQ or troubleshooting section.

> Key: LOG4NET-383
> URL: https://issues.apache.org/jira/browse/LOG4NET-383
> Project: Log4net
> Issue Type: Bug
> Affects Versions: 1.2.10, 1.2.11
> Environment: IIS 7.5 / Win 2008 R2
> .Net 4.0
> MVC3 and WCF applications
> Reporter: Arun
>
> We are running into this issue when we log errors/fatal message using
> log4net.
> > System.Security.VerificationException: Operation could destabilize the
> > runtime. at log4net.Core.LogImpl.Fatal(Object message, Exception
> > exception)
> Strangely this happens only when we log as Error/Fatal, Info and Debug
> messages log perfectly fine. Because of this exception, the real exceptions
> are getting masked and its making it very hard for us to debug in deployed
> environments.
> I have tried searching online but to no avail. Any help is appreciated.
