> The following code completely ignores the Where condition:
> {noformat}
>                 var groupByQuery2 = models.Where(m => m.Value.DateTicks < 10 
> && m.Value.Dirty.HasValue).GroupBy(m => m.Value.ContractId)
>                     .Select(g => new KeyValuePair<string, int>(g.Key, 
> g.Select(m => m.Value.Version).Min()));
> {noformat}
> debugger shows SQL without WHERE:
> {{CacheQueryable [CacheName=someCache, TableName=MODEL, Query=SqlFieldsQuery 
> [Sql=select _T0.CONTRACTID, min (_T0.VERSION)  from "someCache".MODEL as _T0 
> group by (_T0.CONTRACTID), Arguments=[], Local=False, PageSize=1024, 
> EnableDistributedJoins=False, EnforceJoinOrder=False, Timeout=00:00:00, 
> ReplicatedOnly=False, Colocated=False, Schema=, Lazy=False]]}}
