You can create an SQLCLR trigger FOR INSERT to table. This trigger can call a simple WCF Service that you can host in your application. THe assembly with the trigger needs to be registered in SQL Server. See here how to do it.

Another approach (the simplest one): use ordinary SQL trigger that monitors INSERTs to the table and executes xp_cmdshell with a command something like "copy nul /Y some_file_with_path.txt" Your application can use FileSystemWatcher class to watch for modifications to the same file. Configure the filter to watch for last access to this particular file only. See here how to do it. Proxy account for xp_cmdshell needs to be defined on SQL Server.

I faced the same problem a while ago. I also wasn't able to make SQl Notifications work.
