Is log4net able to log somewhere else, in that case, in a simple log-file?

Check your log4net config. You have to use appender for MS Sql Server. Below is the example. Change Database connection string and Table Name as per yours and also make sure you have created table in database.

XML

<appender name="ADONetAppender" type="log4net.Appender.ADONetAppender">
   <bufferSize value="100" />
   <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
   <connectionString value="server=servername; uid=Lion; pwd=Lionman; database=databasename" />
   <commandText value="INSERT INTO Log ([Date],[Thread],[Level],[Logger],[Message],[Exception]) VALUES (@log_date, @thread, @log_level, @logger, @message, @exception)" />
   <parameter>
     <parameterName value="@log_date"/>
     <dbType value="DateTime"/>
     <layout type="log4net.Layout.RawTimeStampLayout"/>
   </parameter>
   <parameter>
     <parameterName value="@thread"/>
     <dbType value="String"/>
     <size value="255"/>
     <layout type="log4net.Layout.PatternLayout">
       <conversionPattern value="%thread"/>
     </layout>
   </parameter>
   <parameter>
     <parameterName value="@log_level"/>
     <dbType value="String"/>
     <size value="50"/>
     <layout type="log4net.Layout.PatternLayout">
       <conversionPattern value="%level"/>
     </layout>
   </parameter>
   <parameter>
     <parameterName value="@logger"/>
     <dbType value="String"/>
     <size value="255"/>
     <layout type="log4net.Layout.PatternLayout">
       <conversionPattern value="%logger"/>
     </layout>
   </parameter>
   <parameter>
     <parameterName value="@message"/>
     <dbType value="String"/>
     <size value="4000"/>
     <layout type="log4net.Layout.PatternLayout">
       <conversionPattern value="%message"/>
     </layout>
   </parameter>
   <parameter>
     <parameterName value="@exception"/>
     <dbType value="String"/>
     <size value="2000"/>
     <layout type="log4net.Layout.ExceptionLayout"/>
   </parameter>
 </appender>
