How can i find out when my program execute a linq expression what sql query has been executed?
Profiling is a sure way. Depending on the LINQ provider, this may also be inbuilt, for example with LINQ-to-SQL you can assign anything to
.Logand it will write the queries as it does them. At the simplest level:Internally, we use a custom ADO.NET stack for this (and some other things). It looks like a
SqlConnection(and LINQ-to-SQL is perfectly happy with it), but it does some logging and profiling for us on every command executed, so we can see where our long running operations are. I think Sam is looking to make this available to the public if you want.
