  </configSections>
  <loggingConfiguration name="Logging Application Block" tracingEnabled="true" defaultCategory="Tracing" logWarningsWhenNoCategoriesMatch="true">
    <listeners>
      <add fileName="F:\Service\Service\log\Full\Service.log" rollSizeKB="1024" timeStampPattern="yyyy-MM-dd" rollFileExistsBehavior="Increment" rollInterval="None" formatter="Text Formatter" header="" footer="" listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.RollingFlatFileTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" traceOutputOptions="LogicalOperationStack" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.RollingFlatFileTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" name="AppLog" />

    </formatters>
    <categorySources>
      <add switchValue="All" name="AppLog">
        <listeners>
          <add name="AppLog" />
        </listeners>
      </add>
      <add switchValue="Verbose" name="ExceptionHandling">
        <listeners>
          <add name="Exception" />
        </listeners>
      </add>
      <add switchValue="Information" name="Tracing">
        <listeners>
          <add name="Trace" />
        </listeners>
      </add>
    </categorySources>
    <specialSources>
      <allEvents switchValue="All" name="All Events" />
      <notProcessed switchValue="All" name="Unprocessed Category" />
      <errors switchValue="Off" name="Logging Errors  Warnings" />
    </specialSources>
  </loggingConfiguration>

Any help will be appreciated

I faced this issue and after spending long time, if found that in my configuration, declaration of "configSection" should be first tag. If there is any other tag before it then it throws same error.

In my case, there was target framework tag before my configsection. I moved it to after that and it starts working
