Upgrading LLBLGenPro from 2.5 to 2.6

This is a pretty short post because it just worked. No pain, no problems.. well, none so far anyway. Install 2.6, open your project, generate, and you’re ready to get LINQing. I wasn’t really expecting it to be a problem, or to be complicated, however it’s still nice when things work as expected. Tags: LLBLGenPro

LLBLGenPro v2.6 released

After 11 months of development, v2.6 of LLBLGenPro is out now. Featuring LINQ support, .NET 3.5 support, optimisations, bugfixes, etc etc – sounds like a nice upgrade. Link: LLBLGen Pro v2.6 has been released! Tags: LLBLGenPro

Some light reading on the Entity Framework

First, Danny Simmons post titled "Why use the Entity Framework" clarifies Entity Framework vs. traditional ADO.Net, Entity Framework vs. LINQ to SQL,  Entity Framework vs. nHibernate etc. Frans Bouma (LLBLGenPro etc) has a followup piece, titled Why use the Entity Framework? Yeah, why exactly? Finally, included as a reference, Frans Bouma's essay titled The Database Model is the Domain Model is useful for anyone who's not read an awful lot about OR/M tools and needs a quick primer. I'm mostly posting these for reference purposes, and partly as Doug might be interested in reading them (/wave) when he returns to places with Internet...

LLBLGenProDataSource2 v2.5 and hosted environments

A while back I mentioned that I was playing about with LLBLGenPro's ObjectDataSource in conjunction with ASP.NET GridViews in order to deliver a simple user interface allowing basic CRUD type operations in little or no development time. I hit a slight snag the other week when I upgraded to release 2.5 of LLBLGenPro. Everything was looking fine until I deployed the solution up to my hosting provider - at which point every page containing a LLBLGenProDataSource2 control started throwing security exceptions. It's always fun debugging issues with a hosted environment. The provider's setup is always something of a black box,...

More real world LLBLGenPro code

I love working with LLBLGenPro. However sometimes I go through a process of adapting what I want to do into LLBL speak. I'm still pretty new to using the tool, so I figured I'd throw up some of the more useful chunks of code relating to real world problems just in case someone else finds them useful. The Problem You have a list of entities, lets call them "Categories". You're dynamically creating a total related to these categories, lets say "the number of images in each category". Finally, you want to filter your result set (using LLBLGenPro -...

LLBLGenProDataSource2, GridViews, and Case Sensitivity

I've been playing about with LLBLGenPro's Object Data Source recently. Mostly because I want to know if it's the sort of thing which could actually be used in a commercial project, or whether it's not quite all the way there yet. In my experience, working with GridView style pages goes one of two ways: They're simple, basic CRUD type operations. Maybe some sorting and/or paging. They're so insanely custom that you might as well have written your own control and not even used a GridView/Repeater. I'm looking at LLBL's Data Source for the occasions which fall into option #1....

Entities out of sync with LLBLGenPro

It's a funny feeling when you come across problem while trying to do something "simple" with a product that you've been using for a while. In my case, I was attempting to work with a LLBLGenPro entity immediately after saving it. Pretty simple really, but it kept complainng about the entity being out of sync. I had to stop and think "Hmm, have I ever done it this way before?" to which the answer was no. Turns out that so far I've never actually needed to work with an entity directly after the save. "The entity is out of...

Developing Linq for LLBLGenPro

Fans Bouma is documenting the process of adding linq support to LLBLGenPro in a series of posts. One of the pingbacks named the series "A diary of LINQ pain" which sounds pretty appropriate! Tags: LLBLGenPro, Linq

LLBLGenPro v2.5 Released

This falls into the "oh crap I have a bit of reading to do" category. The 2.5 release (which is a free upgrade for existing 2.0 customers) has a couple of interesting sounding major features such as auditing and  authorization, as well as a lot of other improvements (such as improved prefetch paths, field exclusion for fields containing large amounts of data, and support for even more database types).
