Do .NET 2.0 SP1 Binaries Fail Without SP1?
Do .net 2.0 service pack 1 compiled binaries fail when ran on machines without that service pack? Developers automatically get force-fed .net 2.0 sp1 when we install VS 2008, which doesn't sound like it should be a big concern typically. But what about the next time you compile an existing VS 2005 app and deploy on machines without sp1, which would of course be the case for most non-dev machines right now? I believe I have found a case where this is indeed happening, at least that's the only explanation I can find so far, and it looks like there are a few others reporting things too -- but the details so far are sketchy at best.
I've got an existing .net 2.0 app (written in C#) that calls a 3rd party web service that has always ran just fine. I needed to make a couple of small updates to my app which did not change anything related to the calling of this web service at all. Everything works flawlessly on my development pc, which has service pack 1 for .net 2.0, but fails when deployed on my qa server, which does not have service pack 1. Here are the exception details: -
Function to Load Enum-Typed Properties from Database
Here's a nice library function useful when loading enum-typed properties from your database:
public static T ToEnum<T>(int typeValue) {
return (T)Enum.ToObject(typeof(T), typeValue);

LINQ to SQL "Real" Example App Available
The Atlanta Code Camp was today, so I finally got to give my LINQ and O/R Mapping talk that I've been preparing.
I tried to have minimal slides so that I could do a deep dive into real code, but I still went a little too long. The slides look great on my own PC, and in fact they're mostly some I stole straight from other LINQ presentions. But the overhead I was using made the text nearly unreadable for some reason, which made me take longer on the slides. It also made some of the standard VS color syntax unreadable, with the work-around being to select that code. I small the same problem with another speaker in the same room, so I guess it was the projector, but very frustrating.
In the end I still got to hopefully show a fair amount of LINQ to SQL, but I had really hoped to show more. I also made sure I gave a glimpse at SqlMetal and LINQ to Entities, but both of those were meant to be just glimpses. Finally, I briefly demoed my new "real" example application written with LINQ to SQL which is included in my download. This example shows off my own POCO objects with an external XML Mapping file, instead of the ugly code gen with attributes. Its also a "real" app that consumes the LINQ to SQL with WinForms grids, drop-down filtering, and create, update, and delete.
Note that it assumes the May 2006 CTP, but I'll update it to the next one when it comes out, hopefully next month. Its also nearly identical to my existing "real" example app downloads that I have for my own ORMapper and NHibernate. -

Atlanta Code Camp 2007 Registration is Open
Registration for Atlanta Code Camp 2007 on January 20th is now open. Space is limited and fills up fast, so do NOT delay registering -- it's free. Thanks to Jim Wooley for putting this together this year.
I'll be presenting a session titled "Linq and O/R Mapping" that will be lots of real code and very little powerpoint. If you've seen the standard Linq sessions already, or even if not, but you've been wanting more then this is for you. I'm not going to waste any time on Linq to Objects or Xml, although those are cool in their right -- I will focus purely on Linq to Sql, and to a lesser extend Linq to Entities or Datasets. Do you want to see a real application built using Linq to Sql? That's what I plan to do, and I'll do it several ways so you can experience the possibilities. For instance, should we use SqlMetal, the GUI Designer, or do our own thing with xml mappings instead of attributes? What if you want to include some relationships, use some stored procs, and even some inheritance? We shall cover all of those possibilities and more -- you will NOT be disappointed since this will not be just another slide deck or sample series based on what's already available. In fact, I would actually challenge you to find any other "real" sample that includes all of these with xml mappings, but you won't find it since it doesn't exist. I hope you get that I'm excited about this, as these technologies have definitely matured past my initial criticisms. And even if you can't make it for some reason, I'll post at least some version of my sample app after the event is over for all to see. -
Which Topic Would You Like to See at Atlanta CE
Which topic would you like to see me present at the Atlanta Cutting Edge .NET User Group (formerly the C# User Group)? I've given a presentation on Custom Providers in ASP.NET at Code Camp that some have asked me to do again, but it would be a repeat, or I can dig into a little known but powerful specific provider and do a presentation on Logging and Diagnositics in ASP.NET. Those are probably the only two options for now, so please give me your preference on these two, but feel free to suggest other topics if you have a good idea and I'll consider it in the future, although probably not right now.

Is .NET v3.0 (aka WinFX) going to be Synced with C# 3.0 (aka LINQ) ?
I think it makes great sense to rename WinFX to .NET v3.0, but I haven't seen any mention as to whether or not this implies any type of sync with C# 3.0 and LINQ, let alone DLINQ and ADO.NET v3.0 Entity stuff -- anyone have anything they can share? It seems like it would be really weird to have .NET v3.0 come out a lot sooner than C# 3.0 and ADO.NET v3.0, and I don't think those are going to be released earlier, so does this mean that part of this renaming entails a delay in WinFX, or should we expect the other things to later be renamed to 3.x or even 4.0? Sorry if it seems I'm ignoring VB, but since its not labelled 3.0 to begin with its not really a problem with this other renaming if it ships later or not.
