Webcast: NoSQL Movement, LINQ, and MongoDB
I'm happy to announce I'll be doing a free webcast in the DevelopMentor webcast series on MongoDB,NET, LINQ, and NoRM. NoSQL Movement, LINQ, and MongoDB. We'll be building out a website in ASP.NET MVC with MongoDB as the back-end using LINQ. Tuesday May 25th - 11AM PST Register here. hope to see you there. There will be plenty of code so it should be fun and educational. Cheers! mkennedy. All content copyright Michael C. Kennedy.

MongoDB vs. SQL Server 2008 Performance Showdown
This article is a follow up one I wrote last week entitled “The NoSQL Movement, LINQ, and MongoDB - Oh My!”. In that article I introduced the NoSQL movement, MongoDB, and showed you how to program against it in.NET using LINQ and NoRM. If there is a database that is 100 times faster than SQL Server, free, easy to administer and you program it with LINQ just as you would with SQL Server then that is a very compelling choice. These inserts were performed by inserting 50,000 independent objects using NoRM for MongoDB and LINQ to SQL for SQL Server 2008. Those were.

  • Processing Text Files with LINQ
    Pretty boring stuff, so my mind started to wander and I started thinking about the loops I was writing and how I could replace them with LINQ. With all of this information, we might write code like the following (without using any LINQ): using (StreamReader reader = new StreamReader("ratings.list", Encoding.GetEncoding("iso-8859-1"))) { bool inReport = false; Regex votesAndTitleRegex = new Regex(@"^ {6}.{10}s+(d+)s+d{1,2}.d The first thing we need is a way to convert the lines in a text file into an IEnumerable<T> –without that, LINQ won’t be possible.

  • Dynamic Sorting with LINQ
    I’ve been working with ASP.NET MVC and LINQ recently and was working on a controller action that “returned&# a collection of objects (wrapped in a JsonResult ). The dictionary needs to hold expression trees and not “raw&# delegates in order for LINQ to SQL to be able to generate the correct query when it finally gets around to executing it. One potential problem: if orderByKey names a property that doesn’t exist on the object or a property that returns an object that LINQ to SQL can’t order by, a runtime exception will be thrown. break; }.

  • LINQ to SQL is dead
    It would appear that LINQ to SQL is running on a dead end track. At PDC the announcement was made that no more investments in LINQ to SQL are made and the Entity Framework will absorb any features that LINQ to SQL has and that are worth preserving. The following message from Tim Mallalieu says it all: Is LINQ to SQL Dead? We will continue make some investments in LINQ to SQL based on customer feedback. LINQ to Entities will be the recommended data access solution for LINQ to relational scenarios. Tags: LINQ

  • The NoSQL Movement, LINQ, and MongoDB - Oh My!
    Interact with the database using LINQ. Shortly we’ll look at an example where we build out a disconnected, offline RSS reader that uses MongoDB and LINQ to store its data. You have several options when choosing how to access MongoDB from.NET but generally that means using LINQ and a light-weight object-mapper on top of MongoDB itself. Then we’d use LINQ to SQL or Entity Framework to generate the ORM classes. We begin by generating the objects (Blog, RssEntry, etc) in memory and then serializing them via NoRM to MongoDB much as you would in LINQ to SQL. Ok, ok.

  • LINQ to SQL to remain alive a little longer? LINQ to SQL changes in.NET 4.0
    I guess the success for LINQ to SQL makes it hard for Entity Framework to absorb the full feature set in a single (v2) release. Here is the list as posted by Damien : LINQ to SQL changes in.NET 4.0. LINQ to SQL class designer. Code generation (SQL Metal + LINQ to SQL class designer). Tags: LINQ The team has been working on a bunch of fixes and improvements to be delivered in.NET 4.0. Change list. Performance. Query plans are reused more often by specifically defining text parameter lengths. Single/SingleOrDefault/First/FirstOrDefault. Usability. SQL Metal.
