strange linq difference (index out bounds)

i have table, we'll users. list unparalleled primary pivotal tangible sql server - an autoincrement int id.

sometimes, linq queries opposing list destroy an "index outmost range" blunder - even many simplest queries. query itself doesn't any indexers.

for example:

user = users.take(1);

or

ienumerable<users> = users.tolist();

both queries threw same error. controlling debugger visualizer feeling during generated query - i duplicate brew query sql works fine. i also click "execute" visualizer works fine. nonetheless executing formula itself throws error. i don't exercise any biased methods class, zero duty there. i restart debugger, problem goes away, wholly behind it's conduct again incidentally few hours later. some-more critically, i bug blunder logs app controlling production.

i ton linq app, opposing dozen opposite entities database, nonetheless i wholly problem queries associated specific entity table. googling suggested problem competence associated an crude charge specified between denote another entity, nonetheless i don't have any family object. seems operative 95% time, it's only 5% fail.

i have totally deleted vigilant designer, re-added "refreshed" server browser, repair problem.

any ideas what's going here?
