RIA Services Validation: Video Tutorials (in VB)

Not too long ago, a gentleman named Bill Burrows (a VB MVP) contacted me and asked for permission to use content from my blog to create a video tutorial series on RIA Services Validation.  I was really flattered by this and gave him my permission.  I apply a Creative Commons Share-Alike license to the content on my blog, so Bill could have really done this without my explicit permission, but I do appreciate that he asked.  I simply requested that he respect the Share-Alike and Attribution portions of the license. Today, Bill sent me an update to let me...

DomainDataSource Enum Filters

In early pre-release versions of RIA Services, the DomainDataSource control did not support filter descriptors for Enum properties.  We were able to get this fixed for our V1.0 RC release though, and I mentioned that back in March.  I said in that post that I’d follow up with details about our Enum support, but I never did (until now). Someone actually called me out on this by commenting on the post.  However, I thought the details of the comment were a bit humorous.  Here’s what I received in my inbox: So, you’ve asked me to point...

RIA Services SP1 Installation Note

With our WCF RIA Services V1.0 SP1 Beta release, we have a known installation issue that we wanted to call out.  In actuality, the issue is not with our SP1 installer, but with our V1.0 RTM installer, but it doesn't surface until you've installed SP1. To get right to the point: If you have WCF RIA Services V1.0 SP1 installed, do not attempt to install WCF RIA Services V1.0 RTM.  If you do, you will find yourself in this strange scenario where both V1.0 RTM and V1.0 SP1 appear to be installed.  What you really have is a union...

Is Silverlight's DataAnnotations a Subset of .NET's?

I was one of the developers that ported the System.ComponentModel.DataAnnotations assembly to Silverlight.  Every once in awhile, someone asks me if the Silverlight version of the assembly is a subset of what is in .NET.  The answer is Yes, but there are some caveats, and I’m honestly tired of regurgitating the detailed answer.  With this blog post in place, I can now simply point people to a URL for the answer.  This is what we call DRY. I’m sure that it goes without saying that the implementation details of the two assemblies differ.  In the .NET version, we have...

Our Apologies to One Guy

Last week, I tweeted about a bug the RIA Services QA team found.  It’s rather obscure and we decided not to fix it.  I thought it was worth mentioning for at least the humor of it. Here’s what you must be using in order to see this issue: Windows XP Service Pack 3 - Japanese Visual Web Developer 2010 Express - Japanese WCF RIA Services V1.0 SP1 Beta (or RTM, since we won’t be fixing the issue) VB And here’s what you do: ...
