Thank you.
This is web applicaton. After Adding MonoDebug line numbers appear.
If I delete mdb file so that there is no mdb file and replace dll file with 
new version I got exception:

0:0 ** (/usr/local/lib/mono/2.0/gmcs.exe:7267): WARNING **: Symbol file
/tmp/www-data-temp-aspnet-0/161e1492/assembly/shadow/f1000cb4/bf017f39_4e01738d_00000001/DbLinq.dll.mdb
doesn't match image

I used mono control panel to start everything but exception still appears.
It seems that mono tries to use old shadow copy of mdb file.
Is this mono bug ?
