Ok, I am the first to admit that I am firmly entrenched in the "Not Built Here" camp. Not only for controls but tools as well. The only tool I've let into Visual Studio for the longest time is Resharper.
I love the power of LINQ but the LINQ to SQL ORM tools have never really thrilled me.
Well, I have changed that rule and I've added PLINQO. I've looked at other tools for ORM, even LINQ to SQL and EF. Thus far I've never liked how the code that these tools generated, but the code that PLINQO generates is the BOMB! PLINQO is like LINQ on steroids, without the roid rage!
Individual files for each table, Generated code does not overwrite custom changes, custom names .... the list just goes on and on.
I could go on and on, but there is a fantastic 70 minute video tutorial here and I guaranty that within the first 10 minutes you will want to pause the video and download PLINQO!
