Currently I'm trying to build an app that will load csv file for indexlist. It's so fast when loading, but if i include the configfile (file that should be included if you want distribute app with net frame 2) it become much more slower. This is what i do: I created app that will load csv (6000 records) to table at start. It's fast without appname.exe.config in the directory. But if i include the appname.exe.config file it becomes much slower. I know, net 2 is not needed for table control only, but later i want to add sql function to get the rest of large database. And for this i must add configfile to enable net 2 function for sql.. Help please?
