I have the following LINQ expression:
var rawData = ( from e in _man.Details
where e.Id == "G00"
select e).ToList();
which when I run with Profiler open I can see causes two separate identical queries. What is the reason for this and how can this be prevented?
Can you check what is the value in EventClass column in profiler. It probably is SQL:Batch Starting and SQL:Batch Completing (or something similar). Which does not mean 2 queries, but the start and end of execution of one query.
