• Congrats to Faisal on his new role on the ADO.NET team

  My good buddy Faisal has moved from MSBuild to ADO.NET . Specifically, he's the Program Manager for LINQ to SQL and the Object Service for Entity Framework. He says you'll hear a lot more from him on these things, but of course if past history is any indication his blogging will be short lived :) Either way, I'm still waiting for him to convince me why I should LINQ instead of SubSonic . The only issue we're really having now with SubSonic is with the JOIN story, and they're supposedly prototyping stuff to address this in the next build.

• Microsoft Silverlight

  A lot of people are very excited about Silverlight , the technology that was formerly known as WPF/E. Jesse says it will give Flash a real run for its money because of a better video story (emphasis in original). Unlike Flash, Silverlight (the new name) will support DRM, it supports the industry standard VC-1 codec used in HD-DVD and Blueray, and it can take advantage of the built-in media streaming capabilities of IIS. As for DRM support, I don't think that's of any real consequence. Jesse claims "companies that want to stream TV and movies over the web, will not consider any method that doesn't allow for DRM protection", but we're already seeing a trend away from DRM. That said, there are certainly things to get excited about, particularly the prospect of cross-platform CLR support and the ability to develop Flash-like applications with the power of the Visual Studio environment (and not having to learn a new scripting language at that). One thing worth noting is the fact that Flash is...

• SQL Server installation problems on Vista? (Failed to compile the Managed Object Format)

  I've been having issues installing SQL Server 2005 tools (i.e., Management Studio) on Vista. I know it works because I was able to get it installed on my tablet also running Vista - I just couldn't get it on my desktop. I thought it might be related to SQLEXPRESS installed as part of the VS.NET 2005 install, but that didn't seem to fix anything. As it turns out, this is related to a corrupt WMI repository - and the fix is quite easy. C:\Windows\system32>winmgmt /verifyrepository WMI repository is INCONSISTENT C:\Windows\system32>winmgmt /salvagerepository WMI repository salvage failed Error code: 0x8007041B Facility: Win32 Description: A stop control has been sent to a service that other running services are dependent on. C:\Windows\system32>winmgmt /salvagerepository WMI repository has been salvaged As you can see, I had to run it more than once - but it eventually fixed the problem. I clicked Retry and the install went through fine. Hope this saves time for anyone else running...

• SubSonic

  We've been using SubSonic lately, which I first bookmarked from Scott's post . Essentially, the project is an implementation of the ActiveRecords pattern from Ruby on Rails in .NET. Or as the authors describe it, , "a toolset that helps a website build itself". I'm using it on a project I'm working on now and so far it's been very useful - though we haven't had to scale yet. We had to slightly adjust our data model to be more SubSonic-friendly, but it's pretty flexibile and even supports stored procedures if you're into that sort of thing (we are). It also "singularizes" the database tables - i.e., a Companies table becomes a Company object, and a Books table becomes a Book object. (Though it does strip the last 's' from Business.... I'm reminded of that old 1-800-MATT-RES commercial). Regardless of future experiences, I can wholeheartedly recommend it to build a DAL for prototyping.

• Managing Exceptions in Framework Code

  One of the long-running debates here has been the use of exceptions for managing workflow. This was especially fierce while we were working on the Javascript framework, but it has died down a little in the strongly-typed .NET world. The two major questions are: ... when should should you return false / null and when should you throw an exception? I've always been of the opinion that a method should only throw exceptions for events that are truly fatal. For example, a search method returning no results is not an exception. However, a method that internally uses that search method may throw an exception under certain scenarios if it was intending on operating those results. Others are of the opinion that everything should be thrown as an exception. The argument is that even something like no results should trigger exception-handling code, and the easiest way to do this is have the callee fall into a catch block. ( I would counter that, even in the catch block, you need to special case different...
