Hi, Like you I am researching this. I have data in a different database (1500 records) that is manage with a linqtosql module in 3.7. I don't want to tie down that data into sitefinity tables. Currently setting up external pages to manage the data, but would like to have a module for it.
I did find where someone has done this with LinqtoSql.
I am going to attempt to duplicate his solutions. I might something on the way. :) It will be another week before I have free time to research again (setting up a new Sitefinity 3.7 site, pretty site by the way). I will post back if I make any progress.
Maybe if Rob (aka Modika on Stackoverflow) is reading this, he can share some sample code for us, and for Gabe to present it in a webiniar.
