does log4net AdoNetAppender support sql server 2008???

Question

Hi, my config file below: very strange, i have spent a day to find out where i am wrong, but still not working, it still not log anything in the database，but i can output them using RollingFileAppender. Also, the store procedure WriteLog is working well.(I have tested it using sql server studio). I have tried to change the connectionType but not working. Unfortunately I dont have sql server 2000/2005 to test, my log4net version should be the latest one: log4net 1.2.10. Any help is appreciated.

Best way to determine what is going wrong is to use dbgview from Sysinternals. If the logging fails you will probably see error messages appearing there.
