In Linq, you can apparently get a meaningful body from and
expression's .ToString(); random question - does anybody know if linq
also includes a parser? It just seemed it might be a handy way to
write a safe but easy implementation (i.e. no codedom) for an
IBindingListView.Filter (by compiling to a Predicate<T>).
Anybody know if this is possible at all?

error seems to occur very randomly but it's occuring enough to be a real
cause for concern. The errors occur a couple times a week and the website is
hit with constant traffic 24x7. Below are the two errors that are
encountered. I had read something about MARS causing errors like this but...

I have a query which I would like to convert to LINQ. I am having
problems finding good examples or references that cover more complex
queries.
Here is the SQL command I would like to rewrite into C# LINQ. Notice
that one of the returned fields "XrefID" is coming from the second table.
This information is very important but its complicating the query expression
in C# The DataContext has the two classes for the two tables...

I've got some pages that use linq to sql. When I look at the
generated sql statements in sql server profiler, I see the same
statements repeated. In the example below (from a linq data source
selected statement), the same sql query is run against the database 3
times at:
oStudent.Count
oStudent(0).lkpstatus.studentstatus
oStudent(0).lkpstatus.statuscategory
Is this the expected behavior? I expected the select to be run only

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.

The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
