Devart Forums

I was having the same error, but the issue was not with lightswitch nor the db connection I created. I spent almost 2days trying to figure it out, checking forums and trying out the suggestions. It was actually a problem within the code of the procedure I was accessing via the lightswitch interface.
If you're accessing some custom server code on your database, debug the code to make sure it's not causing the error. a possible indication that it maybe a code problem within the database, is if the interface'times out' or throws the same 'failure to enlist transaction' error and the debugger indicates an error at the 'con.executeNonQuery()' method.
