On LINQ to SQL, Concurrency and Timestamps

I came across a bit of a glitch in using timestamps for checking concurrency violations in LINQ to SQL and thought I'd share. Say I've got a table like; create table Person ( id int identity primary key , firstName nvarchar(30), lastName nvarchar(30), timestamp...

"When Do Queries Execute"

Julie's got a great post about when stored procedures execute when using LINQ to Entities . It made me think about LINQ to SQL where if I've got something like; using (NorthwindDataContext ctx = new NorthwindDataContext()) { var query = ctx.GetCustomersByCountry...

Mocking LINQ to SQL

Matt Warren has an "interesting" post on how you could hack your way to a mocked implementation of LINQ to SQL - if I had a pound for every time someone's asked me how to do this then I'd have at least 3 pounds :-) Seriously though, there is interest in doing...

You've got to stop calling it "LINQ" :-)

<rant strength="veryMild"> A bit of a personal bugbear. I've met a lot of folks who say things like "How do you compare LINQ and traditional data access?" or something along those lines. Please. You've got to stop calling it "LINQ" :-) LINQ is not necessarily...

LINQ to SQL and SqlConnection ( "when you're wrong, you're wrong" :-) )

ADO.NET Entity Framework - QueryViews, Inline Functions in SSDL
