We do ship a VB.NET version of the feature samples browser (not the showcases) which you can find here on Vista:

C:\Users\Public\Documents\Infragistics\NetAdvantage for .NET 2008 Vol. 2 CLR 2.0\Samples\ASP.NET\WebFeatureBrowserVB

I beleive on Windows XP its in:

C:\Documents and Settings\All Users\My Documents\

Here are the things I'm using now that VB.Net samples would really help with: WebDateChooser, ultrawebtab, UltraChart

Earlier, with the product we shipped feature browser that demonstrated individual controls and their features. These samples came with both VB.Net and C# code. But, recently with huge request from our customers for creating real world application with our controls, we had to switch gears a bit here. We started writing Showcase samples that demonstrates real world application solutions using our controls. These applications are huge and time consuming compared to what we did in past. So, we decided that we will write them only in C#.

We will be re-evaluating if we would continue to add VB samples to our feature browser as they are for the most part single page demonstration of control functionality. If there are any specific pieces of functionality that you like and are having trouble setting the control up for within your application, you can always use control forums or ping our developer support for answers.

I haven't tried it myself  with our sample pages, but there are also code converters available that you can use to convert any C# code to VB, if you want to translate any piece of code and copy it within your application.

Hope this helps.
