I have been playing with C# to Visual Basic converters. There are a few around and I have included the best I came across. However right now there is one clear winner if you want to work with the new language features introduced in Visual Studio 2008 – that is Instant VB from Tangible Software.

Notes:

• I have only had a quick play with these – enough to know they have a place in helping move code over from C#
• I have ruled out a few others I found as they looked very dated
• Most DO NOT understand the new language features (such as LINQ) included in .NET Framework 3.5
• Tangible Instant VB does understand the new language extensions. I am using the demo install with decent results
• I hope SharpDevelop 3 will also support the new language extensions
• IMHO – we should include a converter “in the box” integrated into the IDE … ho hum…
