I was running into an issue where one of my webmethods was taking a large amount of time to return a small set (5-10 objects). I was using LINQ to SQL. I noticed that the LINQ to SQL query was returning all of the rows. After looking into the table a bit further, I noticed that the table included some...
I ran into an issue earlier when trying to return an entity class through a web service for use in an AJAX page. After some quick research, I came across a post by Darren Neimke that referenced Rick Strahl's post about LINQ to SQL and Serialization . For me, performing the first work-around and setting...

LINQ views the Image type in SQL Server as Binary. So, there are a few options that we have. We can either (a) modify our LINQ to SQL class and change the property to Byte() instead of Binary or we can (b) convert the Binary to an array. To do the latter, you can use a lambda expression to obtain the...
One of the nice new features in Visual Basic 9 are lambda expressions. They where actually added as one of the underlying pieces for LINQ. But besides enabling LINQ you can use them in all sorts of places. One of the places they really help me is in places where I previously needed to declare a delegate...
I've recently discovered that LINQ and VB can be confusing. I was attempting to pull the top 10 rows of a table where the column started with 'W'. You'd think after I typed that, I'd figure out the solution. That's not the case. Instead, I struggled. Here's what I originally...
I was looking to separate my LINQ to SQL data layer from the rest of my application. So, I decided to move the files to a class library. This way, when my application builds, all of my LINQ files are found in MyApp.DL or something similar. However, I wanted the class library to use the SQL connection...
It's actually pretty easy and user friendly to obtain the value of the identity column using LINQ. After you create your object and insert it on submit, you can call the identity column's property on your object. For instance: Dim db As New BlogDataContext() db.BlogPosts.InsertOnSubmit(MyPost...

While this may seem a problem if you want to deploy you application on a 64 bits version of Windows it really isn't most of the time. In fact if you change your assembly from the default AnyCPU to x86 compatible it will...
