----------------------------

             Summary: Log4Net.Error throws VerificationException - Operation could destabilize the runtime
                 Key: LOG4NET-383
                 URL: https://issues.apache.org/jira/browse/LOG4NET-383
             Project: Log4net
          Issue Type: Bug
    Affects Versions: 1.2.11, 1.2.10
         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.

Environment details:

    IIS 7.5 / Win 2008 R2
    .Net 4.0
    MVC3 and WCF applications

Here is the logging configuration-
 

       <?xml version="1.0" encoding="utf-8" ?>
        <configuration>
          <configSections>
            <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,   log4net"/>
          </configSections>  
          <log4net>
          <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
            <file value="C:\Logs\ApplicationServices.log" />
            <staticLogFileName value="true" />
            <appendToFile value="true" />
            <datePattern value="yyyyMMdd" />
            <rollingStyle value="Date" />
            <filter type="log4net.Filter.LevelRangeFilter">

            <levelMin value="DEBUG" />
            <levelMax value="FATAL" />
            </filter>
            <layout type="log4net.Layout.PatternLayout">      
              <conversionPattern value="${COMPUTERNAME} %date %-5level %class.%method - %message%newline"/>
            </layout>
          </appender>
          <root>
            <level value="DEBUG"/>
            <appender-ref ref="RollingLogFileAppender" />
          </root>
        </log4net>
        </configuration>
